Cypress - End to End Testing Framework

Cypress is the new kid in the front-end testing market which is gaining popularity amongst testers and developers alike. It can test anything that runs in a browser. Cypress is open source and its community is very active. Cypress tests are written in JavaScript but let that not scare you, in case you are unfamiliar with JavaScript, majority of the time you would be working with cypress commands which are pretty intuitive to work with.

But having an understanding of JavaScript would be really beneficial.. and so I have written a blog and created a YouTube series: JS for Testers to help you with that as well.

Cypress could be used for:

  • Unit Testing
  • Integration Testing
  • End-to-End Testing

These are some of the outstanding features that Cypress boasts of:
CypressFeatures

We will be discussing all of them as we explore cypress and reap the benefits.

Cypress and Selenium

Cypress and Selenium exist to serve a very similar purpose but they are as different as they can be. If you are familiar with Selenium, you will be amazed by how simple setting up and getting things running in Cypress is.

Installation is hassle free, writing test is easy, tests are not flaky and tests run really fast.

All of this has been possible because Cypress isn't built on top of Selenium unlike most end-to-end testing tools. In fact, Cypress' architecture is very different from that of Selenium. Selenium executes remote commands through the network, whereas Cypress runs in the same run-loop as your application.

Cypress Installation

Cypress is all in one. Perhaps this will help you understand:

Cypress Installation

And cypress installs all of this with a single command:

CypressInstallCommand

Let's setup the IDE, create a project and install cypress.

Install IDE

It's a good idea to have an IDE. Visual Studio Code is the preferred IDE for Cypress projects.
You can download Visual Studio Code from here: https://code.visualstudio.com/download

Install Node.js

We need to install Node.js because we need to use npm and npx which get downloaded along with node.js.
You can download node.js from here: https://nodejs.org/en/download/
Once download is complete, launch and run through the installer.
To verify successful installation check the version:



   node -v
   npm -v


Enter fullscreen mode Exit fullscreen mode

Create Project

  1. Create a project folder.
  2. In the terminal go to the project directory and run the following command:

    
    
    npm init
    
    This will create a package.json file inside your project folder.
3. You can open this project in Visual Studio Code.


###Install Cypress

As promised, Cypress will install in a single command: 
Enter fullscreen mode Exit fullscreen mode

npm install cypress --save-dev


This will install Cypress desktop app and Cypress CLI. Cypress desktop app is GUI that can be used to run the test in browser. Cypress CLI helps you run cypress tests headlessly.


###Launch Cypress 

To launch the Cypress desktop app (GUI), run the following command:
Enter fullscreen mode Exit fullscreen mode

npx cypress open


![Cypress GUI](https://dev-to-uploads.s3.amazonaws.com/i/lau3k7ea0n53sb0w3coh.png)

The .js files that you see under examples folder are sample cypress tests downloaded to give you a jump start in the world of Cypress.

#Commands <a name="Commands"></a>

Now, I have been saying Cypress is easy but I don't want you to take my word for it. See for yourself. Read the below code line by line and see if it makes sense to you.


![Cypress Basic Test](https://dev-to-uploads.s3.amazonaws.com/i/brt6f8gonu0h76yz1s4o.png)

Cypress is intuitive because its English-like.

**describe** and **it** come from [Mocha] (https://mochajs.org/), which is a JavaScript test framework.

In the above code we are performing four operations that are most common and would be used in almost all the tests that you write. These are:
1. Visit a page
1. Query for an element
1. Perform an action on the element
1. Make an assertion

Now let's dive deep and explore the different commands cypress provides to perform these four tasks.




[Back to table of contents](#toc)

## 1. Launching / Navigating the application <a name="Command_1"></a>

###<mark>visit

**Purpose:** Visit a URL.

**Syntax:**
   * <code>cy.visit(url)</code>
   * <code>cy.visit(url,options)</code>
   * <code>cy.visit(options)</code>

**Examples:**

```js


// Visit a local server running on http://localhost:8000/
cy.visit('http://localhost:8000/')    

// Visit an application
cy.visit('https://www.acme.com/')  

// Visit an application and wait for 30 seconds for the application to launch
cy.visit('https://www.acme.com/', { timeout: 30000 })

// Submit a form
cy.visit({            
   url: 'http://localhost:3000/cgi-bin/newsletterSignup',
   method: 'POST',
   body: {
      name: 'George Burdell',
      email: 'burdell@microsoft.com'
   }
})


Enter fullscreen mode Exit fullscreen mode

url

Purpose: Get the current URL of the active page.

Syntax:

  • cy.url()
  • cy.url(options)

Examples:



// Yield the current URL as a string
cy.url()

// verifies the curent url is equal to the given string
cy.url().should('eq', 'http://localhost:3000/cgi-bin/newsletterSignup')    

// verifies the current url includes the given string
cy.url().should('include', '/newsletterSignup')


Enter fullscreen mode Exit fullscreen mode

go

Purpose: Navigate back or forward to the previous or next URL in the browser’s history.

Syntax:

  • cy.go(direction)
  • cy.go(direction, options)

Examples:



// Go back in browser’s history
cy.go('back')
cy.go(-1)

// Go forward in browser’s history
cy.go('forward')
cy.go(1)


Enter fullscreen mode Exit fullscreen mode

reload

Purpose: Reload the page.

Syntax:

  • cy.reload()
  • cy.reload(forceReload)
  • cy.reload(options)
  • cy.reload(forceReload, options)

forceReload: Whether to reload the current page without using the cache. 'true' forces the reload without cache.

Examples:



// Reload the page as if the user clicked ‘Refresh’
cy.visit('http://localhost:3000/admin')
cy.get('#undo-btn').click().should('not.be.visible')
cy.reload()
cy.get('#undo-btn').click().should('not.be.visible')

// Reload the page without using the cache
cy.visit('http://localhost:3000/admin')
cy.reload(true)


Enter fullscreen mode Exit fullscreen mode

2. Accessing UI Elements

get

Purpose: Get one or more DOM elements.

Syntax:

  • cy.get(selector)
  • cy.get(alias)
  • cy.get(selector, options)
  • cy.get(alias, options)

Selector: property of an element like id, class etc to filter matching DOM elements.
Alias: giving DOM element a name by which it could be referred later. Defined using the .as() command and referenced with the @ character and the name of the alias.

Examples:



// Find the dropdown-menu with the given class name
cy.get('.dropdown-menu')

// Find element(s) with the given data attribute
cy.get('[data-test-id="test-example"]')

// Create and use an alias
cy.get('button[type=submit]').as('submitBtn')
//...hack hack hack...
cy.get('@submitBtn')     // later retrieve the submitBtn


Enter fullscreen mode Exit fullscreen mode

contains

Purpose: Get the DOM element containing the text.

Syntax:

  • .contains(content)
  • .contains(content, options)
  • .contains(selector, content)
  • .contains(selector, content, options)

Things to note:

  • contains() could start a series of commands or could be chained to an existing series of command
  • content could be: String, Number, RegExp

Examples:



<ul>
    <li>apples</li>
    <li>oranges</li>
    <li>bananas</li>
</ul>


Enter fullscreen mode Exit fullscreen mode


// Find the first element containing some text
cy.contains('apples')       // yields <li>apples</li>

// Find the first element with text matching the regular expression
cy.contains(/^b\w+/)       // yields <li>bananas</li>

// Specify a selector to return a specific element
cy.contains('ul', 'apples')       // yields <ul>...</ul>

// When chained to an existing series of commands
cy.get('#checkout-container').contains('Buy Now')
//This will query inside of the <#checkout-container> element.


Enter fullscreen mode Exit fullscreen mode

Access element by index

You can get the first, last or an element at a specific index in an array of elements using first(), last() and eq() respectively.

Examples:



<ul>
    <li>one</li>
    <li>two</li>
    <li>three</li>
    <li>four</li>
    <li>five</li>
</ul>


Enter fullscreen mode Exit fullscreen mode


// Get the first element
cy.get('li').first()      // yield <li>one</li>

// Get the last element
cy.get('li').last()      // yield <li>five</li>

// Get the second element
cy.get('li').eq(1)      // yield <li>two</li>

// Get the second last element
cy.get('li').eq(-2)      // yields <li>four</li>


Enter fullscreen mode Exit fullscreen mode

Access element by relation

4. Assertions

Before we dive in and see what different cammads are there for assertions, there is a good news - many commands have a default, built-in assertion, or rather have requirements that may cause it to fail without needing an explicit assertion you’ve added.

Here are some examples:

  • cy.visit() expects the page to send text/html content with a 200 status code.
  • cy.get() expects the element to eventually exist in the DOM.
  • cy.contains() expects the element with content to eventually exist in the DOM.
  • .click() expects the element to eventually be in an actionable state.

There are two ways to write assertions in Cypress:

  1. Implicit Subjects: Using .should() and .and()
  2. Explicit Subjects: Using expect

Points to note:

  • Cypress bundles Chai, Chai-jQuery, and Sinon-Chai to provide built-in assertions. You can see a comprehensive list of them here.
  • Using .should() and .and() is the preferred way of making assertions in Cypress.
  • Assertions are automatically retried until they pass or time out.
  • In most cases, .should() and .and() yields the same subject it was given from the previous command. However, some chainers change the subject. The chainers that come from Chai or Chai-jQuery will always document what they return and that will help you know what assertions change the subject and which keep it the same.

should

Purpose: Create an assertion.

Syntax:

  • .should(chainers)
  • .should(chainers, value)
  • .should(chainers, method, value)
  • .should(callbackFn)

Examples:



cy.get('nav').should('be.visible')

cy.get('nav').should('be.disabled')

cy.get('nav').should('have.class', 'active')

cy.get('nav').should('not.have.id', 'Dashbaord')

cy.get('nav').should('have.attr', 'href', '/users')

cy.get('nav').children().should('have.length', 8)


Enter fullscreen mode Exit fullscreen mode

Callback Function:
Say, we have to confirm the text inside each of the three items that appear. We can have 3 commands for 3 assertions:



cy.get('#app div:nth(0)').should('contain', 'first child')  
cy.get('#app div:nth(1)').should('contain', 'second child')  
cy.get('#app div:nth(2)').should('contain', 'third child')


Enter fullscreen mode Exit fullscreen mode

This could be done in a single assertion:



cy.get('#app div')
   .should(($div) => {
      expect($div.eq(0)).to.contain('first child')
      expect($div.eq(1)).to.contain('second child')
      expect($div.eq(2)).to.contain('third child')
   })


Enter fullscreen mode Exit fullscreen mode

and

Purpose: Create an assertion. An alias of .should()

Syntax:

  • .and(chainers)
  • .and(chainers, value)
  • .and(chainers, method, value)
  • .and(callbackFn)

Examples:



cy.get('nav')
    .should('be.visible')
    .and('be.disabled')
    .and('have.class', 'active')

cy.get('nav')
    .should('not.have.id', 'Dashbaord')
    .and('have.attr', 'href', '/users')

Executing Test

To run your tests you have got following options:

  • Test can be executed from GUI and from Command Line
  • Test can be executed in browser and in headless mode Also, the test runs automatically when you make some changes and save it. This comes handy when you are writing the test and want to execute it often to check. This is called 'Real time reloads'.

1. Running test from GUI

Running tests from GUI is easy.
First, let's launch the Cypress GUI using the following command:



npx cypress open


Enter fullscreen mode Exit fullscreen mode

This is how it looks:

Cypress GUI

All the .js files are the test files.

To run any test simply click on it. Cypress Test Runner will open and the test will run in it.

Cypress Test Runner

This test runner is very intuitive and very powerful. The Command Log lists all the commands that ran and when you tower over them, the App preview section would should you the application state when the command was executed. This is the much loved 'Time Travel' feature that cypress provides out of the box.

2. Running test from Command Line

Using command line, test can be execute in browser as well as in headless mode.

2.1. Headless Mode

Using command line, by default, tests are run in headless mode. Cypress wil record videos when running headlessly.

Run a single spec file



npx cypress run --spec "cypress/integration/examples/actions.spec.js"


Enter fullscreen mode Exit fullscreen mode

Run multiple spec files



npx cypress run --spec "cypress/integration/examples/actions.spec.js,
cypress/integration/examples/files.spec.js"


Enter fullscreen mode Exit fullscreen mode

Run all spec files in a folder



npx cypress run --spec "cypress/integration/examples/**/*"


Enter fullscreen mode Exit fullscreen mode

Run all the spec files in the project



npx cypress run


Enter fullscreen mode Exit fullscreen mode

2.2. In Browser

To execute tests in browser using command line, you simply need to add '--headed' (for electron browser) or '--browser browserName' for some other browser. The “browser” argument can be set to “chrome”, “canary”, “chromium”, or “electron” to launch a browser detected on your system. Cypress will attempt to automatically find the installed browser for you.



# for electron browser
npx cypress run --headed

# for specifying your prefered browser: chrome, canary, chromium, or electron
cypress run --browser chrome

I use Cypress now for all my projects and combined with Typescript it’s the only testing I do. No unit or component testing as I find this combination catch’s the majority of issues and it’s it’s fast to develop and maintain.

Good, through run though thanks for sharing

For those using cypress for E2E testing do you simply mock all your API calls?

Has anyone found a testing strategy similar to how RoR does it? Specifically, a test database that gets reset after every run?

I just hate mocking every single endpoint in JS projects that heavily rely on multiple microservices. It becomes an exercise in tedium.

In rails you normally can use FactoryBot through middleware on server side and commands to clean/setup specs in cypress. Doing calls to your real app makes everything updated, no need to write mocks, especially it can be a problem for websocket apps (not enough tools for now to mock websocket). So in other words you are doing integration testing, which is higher level, with easiness of unit testing - which is absolutely great and fast enough.

One of the solutions: github.com/shakacode/cypress-on-rails

I do also like to test the middle-ware directly.

It forces you to keep all the logic away from client code.

If someone implements part of the business logic with a javascript in the browser ... that is not secure and might not end well in some cases.

My opinion is that the browser code should be used only for usability requirements. And those use cases need also test, so +1 for cypress for helping on that.

Nevertheless the middleware / APIs should be tested directly, also for preventing those invalid input cases that the interface might never send, but that might break everything.

Do you define all your interfaces by hand ?

In the case of REST endpoints, the same code generator (Ex: openapi-generator) that generate the endpoints from the API specs (Ex: OpenAPI) might generate the client library with basic unit tests.

I recommend using Cypress Testing Library to extend the commands cypress can use. I very rarely use cy.get and instead use the commands that Cypress Testing Library gives you.

You can do things like cy.findByPlaceholderText, cy.findByText, or cy.findByTestId for hard to grab elements. And retries are built in if I remember correctly.

If you have more than one element that matches you can just add All after the find, for example cy.findAllByText and if you want to grab the first you'd do cy.findAllByText("hello button").eq(0).click()

Hi Bushra,
Thank you for the very good article. I am new to cypress and javascript. please help me with below code. trying to get latest string value and compare it in while loop. but in while loop it keeps picking up old string value.
Thanking you in advance. Really appreciate your help.

allOpenCases.getCurrentSystemStep().then(($currentStep)=>
{
return $currentStep.text()

}).as('CSS')

cy.get('@CSS').then((cStep)=>{
let count = 1
while(cStep!==targetSystemStep && count < 50)
{
allOpenCases.getSearchButton().click()
cy.wait(3000)

allOpenCases.getCurrentSystemStep().then(function($currentStep)
{
let cStep = $currentStep.text() //latest text

})

count ++
}

})

Uh, using Cypress is such a bad experience.
I tried it because a colleague heard about the hype.
All your posts seem to be related to Cypress.
Why is that?

I just finished figuring out how use Cypress combined with XState for auto-generated model based tests. I also wanted to mock API responses a little differently than Cypress suppports out-of-the-box currently but I was able to make it work. I really like that I can review the test at each stage with Cypress. Anyways I posted about my experience here: dev.to/rjdestigter/model-based-ui-...

Agree Cypress is evolving however it can be fit everywhere. Not sure but it does not provide a free hand in using all the JS capabilities like in wdio. working with nested iframes is a pain. I don't want to change/manipulate the dom just to handle the new window opened by a link.

Also, on the architecture, I am not able to launch the url hubspot.com/ in Cypress but in wdio or playwright that's not a issue

We've been using Cypress for now one and a half year. It's very good and easy to use

Awesome! Thank you so much for sharing. I'm trying to implement Cypress in our React App.

There are just few things I don't get... should we use our real graphql service (in my case) to test the data or it's better to mock the graphql requests??

If we should mock the service data.. it's not complicated to maintain the tests every time the requirements changes? Thanks in advance!
