End to End Testing with Cypress - Beginners tutorial

youtube what's going on man listen i have uploaded a lot of videos but this one is absolutely special we're going to talk about end-to-end testing cipress and at a very beginner level that you can understand easily and then apply on your react projects angular projects view projects it doesn't matter you can just apply this everywhere on every web application so watch the video till the end where we go through an entire application and we kind of write end-to-end test cases just like you would implement in a real world application now i have said this before but i'm gonna say this once again like the video and subscribe to the channel because it's free and just this action done by you can promote this video to thousands of developers for free and a lot of beginners would get to learn new content from my site so today we are going to talk about angular and cypress and basically cipress and how we can test different web application with cyprus and the beauty of zippress is that you can use it with any framework whether be it react angular vue.js or even an application that has no framework at all so you just need a website that you can test your code at so essentially it's really easy to use and one of the reasons that we write e2e tests is sometimes we want to test out complete flows for instance a user goes to this page tries out this button and then does this action and then this should be the expected scenario so as we know we have two kind of tests right now uh or maybe more even but there are two main kinds one is the unit test and the second one is the e2e test or the end-to-end test here we are going to talk about end-to-end tests which are also sometimes called integration test in which we have an entire flow and then we expect things to be done after performing a certain action why cyprus and why not something else that is also one of the questions for instance angular comes up with protractor and by default when you when you have an angular application for instance this is the code that i'm going to be using right now um so essentially when you have an angular application you do have some config for protector for instance if you go to the e2e folder on a fresh angular application you will find protractor.con.js and you can basically run e2e test out of the box with protector the reason why we use cyprus is that the api of cyprus is so easy to implement that almost anyone can do it even qas can do it even business analysts can do it after some some efforts and obviously some learning but essentially it's really easy to learn so today what we are going to do is that we are going to try out a simple angular application um if you want to follow through you can do it right now in the project we have mainly two branches one is um one is the main branch and the other one is i believe the start here branch yes so you would want to go to start here if you're watching this video even in the future because we would have a final branch as well in which we will have the final code or it might be the case that we have the final code in the main branch but essentially go to the start here branch what i've done so far is that i've just um just cloned this repository so if you're familiar with git obviously what you would do is you would run git clone and then this url and then it will clone into a folder named ngc press starter once you are in there you can open it into your favorite editor for this video i'm using code because i use vs code all the time and then you can just cd into it and then run npm install which will install all the package dependencies for this project once you are done with this we are ready to go and this is what the code looks like then so essentially what we want to do as a first step when we are working with zippres is we need to install zippres into our project so if i go to cypress.com and show you this uh really cool uh headline you do it just like this npm install cyprus now um since we have this project or this package cyprus only as a dev dependency and it shouldn't go to production for instance where we deploy our code in the end we can install this as a dev dependency before doing so uh i just noticed that we are in the main branch so what i'm going to do is i'm going to check out the starter branch or start here branch i'm going to zoom in a bit so everyone can see this if you have any questions make sure to type in the chat and i can follow through so you will do a get check out start here and this should check out the branch for you and then you'll do a npm install dash d and then cipress this should install the suppress package in your local repository or in your machine for this particular project once you are done with this we will have to create kind of a script that we can run for starting cipress so let's quickly wait for this to be done in the meantime we are going to go into the package.json and here we have already a lot of scripts like ng uh start build so we are going to just create a script called start suppress and essentially here we'll say press open this is the command that we will run to just start the cyprus now in order to just run the project what i need to do is i need to do npm run start or npm start however you would want to call it so i would just say npm start and essentially this command runs ng-serve so let's have a quick look into the application itself while we have the suppress being downloaded all right so this is the application that we have right now uh it's really simple application but with a couple of cool functionalities for instance this is a chat application so what we have is a seed um or how would we call the initial messages that we get when we open the application so you can see that we have different images just ignore this but we have the same message when we open the application these are just dummy messages and then i can just say let's say hello world and then this message will be added i can add more things here and then all of those things would be added uh in the chat um what i can do is that i can delete a message from here for instance i could press delete here and you can see that it's gone i can also click an item and go to its detail page so obviously a good user experience to show a highlighted background and this uh this pointy cursor when an item is clickable so when you click on this you go here and you see the message here and then what i can do is that i can also press delete and go back to the previous page now let's delete this perfectly fine message so i if i go back you can see that the message is gone okay so this is the entire functionality that we have right now we have two different pages chat and messages and then we have this functionality of adding a chat message and deleting a message now that we have cpres uh installed in our system we can quickly go here and we can add a new tab in which we'll run the command for start ciprus we can also do it in the terminal as well but i'm i'm going to run it here so npm run start suppress this should uh this should give you this message if you are installing or if you are running say press the first time and the good thing about zippers is that you have this browser window that you can you can see you can interact with and you can follow all your tests through it so the good thing about installing zippers into any new project is that when you do it suppress already creates a bunch of tests for you to work with and you can you can easily see those tests and how how they work and then you can start copying even copy pasting code from there and then kind of following through it for instance we have these example tests right now i can go to this one actions.spec.js and if i go here okay i need to allow access let's do it real quick this is what you get so you see it's a really good ui and in this ui we will have our tests loaded uh the first time and then we'll have them running one by one and then we can see what is the outcome of those tests so we have this these tests for type so what it's doing right now is it goes to this url and then it performs a bunch of actions and then it asserts or checks if a thing is valid or not you can see that on the left side we have these stick marks if there was any test that would have failed we would get a red light here now one really cool thing about cypress is that if i open a particular test i can follow through all the actions performed one by one so it's sort of a time travel debugger that you can work with for instance in this test you can see that it first did get action email which kind of got this input the email and then it did a typing or on this email called fake gmail.com so you can see on the right side exactly on the input it is changing the content to before and after so before it was nothing and after it it wrote fake at gmail.com or email.com and then it asserted if this was true or not but i'm not going to go into a lot of details here rather we'll just go ahead with creating our own test for our own application so i'm going to close this one now and you can see that there are a lot of tests that we already have right now so what cypress did for us is it created this folder as you can see it's green uh so that means we have added this so we have this folder created and we have this file created as well which is press.json and this file is right now um an empty file what we can do is that we can ignore all of the tests in the in the integration example folder so there this is the examples folder that we have so what i'm going to do is that i can try um do uh insert snippet and see why cpus config and here we have something um for us so what this configuration does or suppress.json does is that it tells suppress what to do and what not to do based on certain variables for instance i'm telling cyprus to ignore all of the files in the example folder so if i go back to uh my c press you can see that it says no files found note has found so it's ignoring all the examples uh tests and the next thing that we need to do is uh provide a base url since we know that our tests would be running at localhost 4200 i could change it to the production url as well uh it depends on what we are trying to test or what url we are trying to test so what this helps me in ciprus is that when i write tests i can provide relative urls rather than writing https localhost 4200 every time everywhere so i can just use for instance in the test i would just use slash chat and then that should be enough so i'm providing a base url for this test now that we have done this we need to write our first test i'm going to create a new file inside the integration folder so we are going to call this app.spec.js so the first thing that you need to know about um about zippers is that what is a context and then how we write tests so i'm going to copy paste this really quick uh because that's so much fun uh let's see so um what we have here is these uh type references for surprise the context is basically the suit or the context that you are testing in for instance i'm writing this test for app so i'm going to write app level test on this context now what i want to do in this test is just visit uh the slash url which is the root of our application so what i'm going to do is that i'm going to just run one dig integration spec click here and then it will load our test and then finally it will do what we want to do it says no test found because we haven't written any test we have just written a command that you should go and visit a slash so to write a test we use the it method and then the convention that we use for writing a test is something like it should do blah blah something so essentially what i want to test right now in our application is uh this has a title that says ng suppresses starter and title is something that is bound to an html for instance you can see installing cprs documentation this is something that you see on on your browser's tab bar this text is not related to title this is a different thing and this title is a different thing so what i want to test is what is the value of this title here so what i can do uh is i can go and um basically start writing this test and it takes the string as the first argument which is the description of the text so i can say it should have the title uh the value of which was ng um what was that suppress starter let's make a mistake here and to see what what happens if we make a mistake and this is really handy in some sort of or in all sorts of test driven development so i'm going to close this a bit so we can see more code and what we want to do here is that we want to check the value of the title so we have to use this cy this is how you start writing tests and then it has a lot of utility functions one of which is title so i can simply say c y dot title dot and then i can say should and then i can provide this an operator and then the expected value so the operator that we can use is eq which means equal to and this is an assertion that we are trying to uh trying to work with so we are saying hey the title should be ng suppress starter okay so we save this go back to our zippers which i can do easily here and then click here i think i already have opened them here yes i have so if i refresh you see that it visited and then it it is trying to do something and then it fills with an error and the test clearly says that expected ngx suppress starter to equal and g suppress starters with the z this equal or the thing after equal is what we were expecting and this is what the actual value was okay so you can see all of the steps in here and it also tells what test is failing or which assertion basically is failing and you can also view this track trace from here as well but i know where the problem is so i can just go here and then i can press save and then this assertion is working fine so we have our first suppress test working yay now to the actual job this wasn't anything the next thing that we want to do is we want to make sure that we get the initial set of messages right away when we open the application so so to say the seed messages so what i'm going to do is that i'm going to create a new file here and then i'm going to call it um chat.spec.js in here i'm going to do a really quick copy paste i'm going to change the context to chat and then before each visit we need to go to slash or by default if you if you notice the url the default url when we land is redirected to chat because chat is the main page that we land on but it doesn't matter so i'm gonna just put it uh here now uh instead of this test what i want to check is to be able to uh see if we have messages or not so in order to do so what i can quickly do is that i can say it should have the initial dummy messages and the second argument is as i mentioned the the callback function which basically defines our test or the logic within the test and then what i need to do is to be able to check if we have the list available um or not so in order to do so what i can do is i can first try to see what is the uh what is the selector of this particular element so if i go and check the message list you see that we have um i should bring this to sides to look at better edit so we have this messages list element which is basically a div so it has a class message list then we have inside a div which has a class message item so what i would want to do is to get all the items you can quickly try to do it in the console as well doing a document.query selector all and inside you can just put this and this so you see that we got a node list of four items uh if i hover on off all of them you can see that they are targeting these now what i want to check is are there four messages on the view when i open this um this application awesome so what we need to do is we need to go to the code and then we will do a cy.get this get method accepts a selector which is equal to the css selector that that we use so in order to do so i could directly write message item but i'm uh i'm a big fan of writing uh kind of hierarchical selectors which makes it more robust so what i can say is that i we have messages list and then messages item so i can do a dot message list and message item and once we have this then we have to check what is the length of these values so right now what i can do is that i can say expect something something for instance i essentially i should do something like hey messages to have length 4 something like this okay but the thing is that this this doesn't return the list of item although what we can do is that we can use a should method here and inside we can provide a callback function just like this this callback function essentially gets the div elements or the dom elements so i can name this let's say messages list and then here i can expect the messages list to have length four let's make it a three to see this failing so i'm going to go back to my zippers on exactly to the browser and then we are going to refresh so let's see we went to the home page and then it's trying to do something and then it says timed out returning after 4000 milliseconds too many elements found found four and expected three so we wrote in our code to expect three items but actually it should be four since we have four messages and this should essentially fix our test so if you go here you can see that it tries to get so it first goes to the url and then it goes to the messages which it finds using the selector and you can hover over it and check it out and then it expects things to be working fine which it does so you can see how easy it is to work with cipres to write e2e tests because you can work with the selectors and you can also then assert different things based on your your business logic so now that we have uh written this test the next thing that we need to do is to make sure hey what if i type something and then click this button should it actually add the item so in order to do so we'll we'll do some some more magic um let's quickly try to write a new test so what i'm going to do is that i'm going to go to here and then i'm going to say one question that zweig is asking we can only get chats via elements id or class or we have more methods to get really good question one of the things is that this cy dot get is uses a selector so it's a css selector now you can use by id you can use by classes you can use by attribute names it doesn't matter it depends on you how you want to achieve different things in the book that i'm writing i have used um a pretty complex query as well which includes things like how you would find an element that has an attribute that starts with a particular word so you can also write complex queries uh for cy.get now jumping onto the next task which is or the next test which is it should basically add a new message to the list so it should add a new message to the list um one of the things that i would like you to focus on is the naming of the test which is really important anyone that opens this file should be able to easily understand what this test is about and what it should do and then obviously you should also be able to understand what you're writing so the first thing that we need to do is we need to write into the text area so i'm going to go back to my my app and try to find out what is the selector of this text area so this is a text area and we need to type into this text area so in order to do so you see that in this text area we do have some classes like cdk text area blah blah uh the chat input so we can either get this chat input or we could use something like writebox change input it depends on you so what i'm going to do is that i can simply say cy.get and then i can try providing chat input for instance all right now the next thing that we need to do is to type into this uh this chat box so we have a method already that is called type and inside we can provide the string value that we want to try out with so we can say hello world and that should be it so we get the input we type a value inside it and then we see what happens so i'm going to go back to zippers and not suppress but here so we have this and what we have written so far is that we go to the url and then we find the chat input and then we type hello world so notice that how it it shows before and after so before it was nothing and now it is the value and now we have to press this button so let's go back to chrome and try to find out what is the selector of this button so it's called send button and inside we have a button now this button has button and button primary class which is what you get from bootstrap i would not recommend using these classes because they are bootstrap classes and you could have many buttons on the screen with these classes so you have to be specific about the selector that you're working with so i'm going to go ahead sorry i'm going to go ahead and do a cy.get or cy dot get and then i'm going to say send button and then the button inside now one important or one interesting thing about surprise is that i can i i do this like ci dot get all the time but i can actually chain all of these methods together just in one go something like this and this would still work so all these methods that we see they are chainable which means that i could do something like this and you will you will find a lot of examples from other projects that they do this so what this does is it's is that this means c by dot get this guy and then c by dot type in the element and then cy dot get this button and then do something else so inside here we are going to say click which means that we are going to find this button and then we are going to click on it um and then let's try this so we have this here and then what it happens is that it finds chat input types hello world then it goes to here and then it presses click so once it presses click you see that the item is already being added into the view so we have most of the work done for what we wanted to do and now we just have to check the length of the items so essentially before we had only five or sorry four items and now we have almost five items so we could do something like this and this and then we could say the length should be let's say five and if we save this go back to our code you see everything passes we have four elements in the beginning we went to chat input typed clicked the button and then we checked out the list and then the list had five items super awesome one of the things that i would do when writing this for an actual project would be to kind of make this thing a utility function so i don't have to repeat this all the time for instance i have copied this here and then here and then here so yeah it's not a really good idea to copy things over and over but for the sake of just learning i think this is fine we can we can go with this all right so one more thing that we have done now the final thing that we need to do is we need to be able to delete a particular item so for this one we are going to pick let's say any item let's say this this item how are you doing and when we delete uh or even when we press the delete button we see this going away now one of the things that is really interesting is that this functionality is dependent upon a person hovering on the item which means that this item might be visible or might not be visible so first of all in order to click something you obviously have to have that on the view so you can perform the click on it how do we tell cyprus to click on an item that is not there initially so if i go to my surprise you see that there's nothing highlighted at the moment so one of the things that we can do that is really interesting it in cyprus is that we have a couple of ways to to do uh this which means if something is not visible make it visible and then click on it so first of all i'm gonna type the description of the text this is should remove a message when the delete button is clicked from the list and you don't have to worry about how long the description should be uh it's it's up to your choice um but yeah essentially i i like to have it as descriptive as possible now i'm gonna just bring it a bit down so i can see more things all right now what i need to do is i need to basically get all the items and then i need to select one item out of them and then i need to be able to click the delete button so in order to do so what i can actually do is that i can use this same method which brings all of the items now i have to select one of them okay there's something called dot eq method which gets a particular item from the list so i'm going to use this how are you doing which is uh at the index 2 since the indexes start from 0. so 0 1 2. so what i can do is that i can use the eq method here and then i can use 2 and then what i need to do is i need to be able to find this delete button inside this message so in terms of hierarchy what we have is that we have a message item inside we have this button so we need to be able to say to suppress hey find this message item or get this message item and then find this delete button inside the message item so we are going to go here in the code and then we are going to use a new method which is called find and then we should be able to provide a delete button here now one of the interesting question is why can't we use this get method and that would be a really good question the reason we are not able to use the get method is that every dot something something means c y dot get it doesn't mean what you found earlier dot find or dot get so if we do a get here we will end up in finding a lot of delete buttons because this will find all the delete buttons in the view and if i show it to you you can see it here so it found all the messages got the item at the index 2 and then it did a cy dot get delete button as you and you can see that on the right side we have four buttons highlighted so it found all of them instead of this we need to use the find method and then we should be able to get the right element so if we use a find you can see get eq2 and then find and you see that the right button is highlighted at the moment what do we have to do now really simple we need to be able to click this and once we have clicked this then we have to check initially the elements were 4 now are the elements three so we do this we go back and then we wait and we see if everything works all right so it seems like um cy.click failed because the element is not visible awesome this is what we talked about the element is not visible and we need to be able to click it anyways one of the things that we could do with this click method is we can provide an object and say force and set it to true this way even if an element is not visible it is still clicked and now you can see all the test pass i'm going to reload it to show you one more time so it goes there finds it clicks the button and then you can see that the item disappears after it and then we try to get all the list of items which are three in number and then we assert that the length is three awesome source so one more test written one less thing to do all right now there's one more thing that we talked about is if i click on a particular item we should be able to go to the details page of this message so we should be able to go to this url and that should be it now just notice the sequence of tests that i'm writing i'm writing about all of all of the events that are possible or all of the actions that are possible on this particular page i'm not talking about hey what if i delete this button i'm not going to put that in the chat test i'm going to put that in the message test later on so from this page i can click on an item and i should be able to go to the url that of that item so in order to do so what we can do is that we can say that hey we have these four items let's take for instance the fourth item which has the eq 3 because of the indexes and then when we go to this page the url should be localhost 4200 slash messages or slash message slash three this is what we have to test and this is how we identify hey if i click this did i actually go to the message detail page how would you identify just like this another way would be to just check the message property or compare this uh message text but i think the easier way is to um just see the urls so in order to do so we'll go into the code and then we should just say that shirt navigate to the message page on list item click or i could say message item click and then we should be able to just write this code so we do a cy dot get let's let's copy paste with with pride so i'm gonna just go here do this instead of two i'm gonna press three y so we get the third um or the fourth element basically so number minus one is the eq now when we get this we need to be able to just click this item and that's all so when we click this the url should change and then we should be able to assert that the cy not cry the cy dot url is a method so i'm going to use the url method and then we do a should and then we since we are comparing we should use the eq operator again and then we provide it with a really solid value so let's test this out if i go here and then i go home page and then if i press the 4 button this is the url that i get so i'm gonna just copy this go here and paste this as it is and now if we save this go back to our test try to see what happens is everything works so we have the message list it got the fourth item it clicked on it the url changed from before to after okay and then the url changed and we saw the message and then we asserted that the url is what we expected and now we have a test now the good thing is that if any of these functionalities fail for any reason for any bad code for any weird release we should be able to just see that right out of the box now we are going to write the final test for this one and in order to do so we'll just create a new file and this is going to be our last test suit so i'm going to go here and say press and then i'm going to say hey um just create no not the same as but in the integration folder message.spec message.spec.js and here i'm going to quickly go to here copy call it message and then what we do is that in this particular case we should be able to actually use the url so what i'm going to use is instead of using slash i'm going to try this one out okay so slash message slash 3 which is the url for uh for a different thing uh i've got a question can we place the values dynamic like length of chat element index message user id yes we can do that as well what you would do in that particular case is that you should have a way to tell cyprus what is the id that needs to be clicked so in order to do so you would potentially go here and add an attribute to each of this div let's say an attribute that's that defines its id and then in the test you first get the id then you click and then you kind of identify that hey the url is this one what is the id after this url and then you can then check the user id so you would have to do some some efforts uh in keeping it dynamic i hope that answers the question if not uh do let me know all right um so back to messages so we are going to this particular url that's good and now we need to be able to see if we can delete a particular message for instance what would happen is that we will go to this page and then we'll click delete and then what happens is that it goes back to the previous url so the url changes that is the first assertion and then the second instruction is that the items should have reduced from four to three so let's write this code now um in order to do so we need to know what is the selector of this button so it is again button button danger not a really good class to work with i would rather go and do a card body and then button danger just to make sure that i don't um i don't mess anything up in in the entire page so in order to do so we'll just go here and then first let's let's write a good description of course should delete the message and go back to the previous url or go back to homepage i would say home page and first thing first we need to get the delete button so we'll do a cy.get and then here we say hey card card body delete oh no button button danger oh i also remembered one really cool thing and that is we can also say get a particular element by its text which is really easy so i can actually say get the delete button from the page in order to do so what i could do is i can get the card let's say just just get the card and then i could say contains and then i can provide the text value which is delete when i do this i should be able to actually get the delete button so in messages and also one more thing to uh to tell is that it's running all the specs but i can actually go and run a particular spec for instance you click here to run all the specs but if i just want to run message specs then i would just click message and then it would run only the message specs now you can see that it goes to message three and then it gets the card and then it contains delete so it actually gets the button just by its text so this is a really handy tool anyways we got the delete button then what we need to do is of course doing a click once we do this we can then assert the cy dot url then we say it should equal and then it should be the home page so the home page is essentially not http localhost 4200 why not because when we delete we go back to the home page which is the slash chat page so we need to assert this and not root so we are going to just paste it here and then finally we need to check the messages list that they should have reduced so if i see here the tests are passing you can see that when when we click the delete button then the new url changes and the url then becomes chat and you see that the um that the message is gone of course so the final test would be exactly the same i'm gonna go here copy the code come back here paste it right away and then i would expect the length to have reduced to three now i save this and if i go back to cyprus you see that all the tests are passing we have get click then url changes then we assert then we get the messages list and then we assert the item's length to be three and that is it now i could be um i could be a noob and i could just write all of these tests under one file with all the flow or even in one test why not but that's a really bad idea and each test should be absolutely isolated from each other and we should have a context of each test so we know which tests are failing and this time travel debug is is something really awesome because anyone can identify where things are going wrong for instance if i change the text of this delete button to say delete message so i'm going to go and go to the message and i'm going to just say delete message and as soon as i do it i go back here i try it out so it tries to find the delete with delete oh awesome so it's using a regex although if i had changed this to something else maybe called remove then obviously this would fail and one one really interesting thing is that you would know something is failing if it takes a lot of time otherwise it's super super fast you see it kind of waits for 4 000 milliseconds like four seconds and tries to do the same thing again so you can see the delete wasn't found we found the card but this is what we failed with and it also gives you the line number where it failed so it couldn't find anything but delete and now we have to update our test as well i'm gonna put this back here and now we are as good as new and that's pretty much it for the session now i can look at the questions how we can tell the order of spec files to be executed the order of the spec files do not matter because we don't we should not write them in a way that they should be executed in in a sequence so every test that we write should be absolutely isolated by that i mean every context should be completely isolated which means that the app context should not be dependent upon chat similarly even within one context all of the tests should be completely isolated and they essentially are isolated for instance you see that we run these tests like um for the chat right so if i go back to the test can i go from here yes i can so even for the tests for chat you see that we run initial dummy messages then we add a message which essentially in the end becomes five messages but then when the next test starts you see that we go and visit the page again so each of the tests is essentially not linked to any anything else for each test we navigate to the page so it starts from the beginning then we get some data and then we perform some actions if you want to do something in sequence you have to write that in a single test to be able to execute all of the things at once but it's it's quite a rare case but it's possible that you have a case to work with uh cancerpress test network calls as well yes really good question cyprus can can intercept network calls and you can actually mock the network calls as well if you don't want to [Music] have your application hitting your server time and again or in fact to get data for instance um you can definitely mock data with uh with zippers uh this is some some of the things that i have uh planned to write in my book as well so stay tuned for that or you can google and you will find uh certain information on that as well but yes uh cbs can test network calls or an intercept network it can test network calls as well it can also intercept network calls now it depends on what you mean by testing network calls do you do you mean that you do a network call and check what data came uh came back because that is potentially not the use case for um for e2e test for web application that is more of a use case for back-end end-to-end tests so if you're talking about checking the network called data then uh then that's not something that cppress is perhaps more suitable for although um the e2e test that you would write would be hey i do a network call i get back data then what do i show on the ui do you have do i have something changed for instance i did a login and submitted a form then there should be a network call gone to the server uh something should have come back uh and do we show a toast of success if we show a toast of success that means that the network call was successful right or it could be your mock call but but then essentially we are interested in what happens in the in the ui for the user so if suppress is most uh suitable for that kind of use cases it's your front-end end-to-end testing tool i really hope that you like the video if you did press the thumbs up button and also subscribe to the channel so this content can reach thousands of developers as i said before as well happy coding take care of yourself take care of each other and i'm gonna see you in the next video you
