Using Cypress

How do I get an element's text contents?

Cypress commands yield jQuery objects, so you can call methods on them.

If you're trying to assert on an element's text content:

cy.get('div').should('have.text', 'foobarbaz')

If the text contains a non-breaking space entity   then use the Unicode character \u00a0 instead of  .

cy.get('div').should('have.text', 'Hello\u00a0world')

You can also use the cy.contains command which handles the non-breaking space entities

cy.contains('div', 'Hello world')

Tip: watch the Confirming the text with non breaking space entity video.

If you'd like to work with the text prior to an assertion:

cy.get('div').should(($div) => {
  const text = $div.text()


If you need to convert text to a number before checking if it is greater than 10:

cy.get('div').invoke('text').then(parseFloat).should('', 10)

If you need to hold a reference or compare values of text:

  .then((text1) => {
    // do more work here

    // click the button which changes the div's text

    // grab the div again and compare its previous text
    // to the current text
      .should((text2) => {

jQuery's .text() method automatically calls elem.textContent under the hood. If you'd like to instead use innerText you can do the following:

cy.get('div').should(($div) => {
  // access the native DOM element

This is the equivalent of Selenium's getText() method, which returns the innerText of a visible element.

How do I get an input's value?

Cypress yields you jQuery objects, so you can call methods on them.

If you're trying to assert on an input's value:

// make an assertion on the value
cy.get('input').should('have.value', 'abc')

If you'd like to massage or work with the text prior to an assertion:

cy.get('input').should(($input) => {
  const val = $input.val()


If you need to hold a reference or compare values of text:

  .then((val1) => {
    // do more work here

    // click the button which changes the input's value

    // grab the input again and compare its previous value
    // to the current value
      .should((val2) => {

How do I compare the value or state of one thing to another?

Our Variables and Aliases guide gives you examples of doing exactly that.

Can I store an attribute's value in a constant or a variable for later use?

Yes, and there are a couple of ways to do this. One way to hold a value or reference is with closures. Commonly, users believe they have a need to store a value in a const, var, or let. Cypress recommends doing this only when dealing with mutable objects (that change state).

For examples how to do this, please read our Variables and Aliases guide.

How do I get the native DOM reference of an element found using Cypress?

Cypress wraps elements in jQuery so you'd get the native element from there within a .then() command.

cy.get('button').then(($el) => {

How do I do something different if an element doesn't exist?

What you're asking about is conditional testing and control flow.

Please read our extensive Conditional Testing Guide which explains this in detail.

How can I make Cypress wait until something is visible in the DOM?

Cypress offers you many robust ways to query the DOM, all wrapped with retry-and-timeout logic.

Other ways to wait for an element's presence in the DOM is through timeouts. Cypress commands have a default timeout of 4 seconds, however, most Cypress commands have customizable timeout options. Timeouts can be configured globally or on a per-command basis.

In some cases, your DOM element will not be actionable. Cypress gives you a powerful {force:true} option you can pass to most action commands.

Please read our Core Concepts Introduction to Cypress. This is the single most important guide for understanding how to test with Cypress.

How do I wait for my application to load?

We have seen many different iterations of this question. The answers can be varied depending on how your application behaves and the circumstances under which you are testing it. Here are a few of the most common versions of this question.

How do I know if my page is done loading?

When you load your application using cy.visit(), Cypress will wait for the load event to fire. The cy.visit() command loads a remote page and does not resolve until all of the external resources complete their loading phase. Because we expect your applications to observe differing load times, this command's default timeout is set to 60000ms. If you visit an invalid url or a second unique domain, Cypress will log a verbose yet friendly error message.

In CI, how do I make sure my server has started?

We recommend these great modules for this use case:

How can I wait for my requests to be complete?

The prescribed way to do this is to define your routes using cy.intercept(), create aliases for these routes prior to the visit, and then you can explicitly tell Cypress which routes you want to wait on using cy.wait(). There is no magical way to wait for all of your XHRs or Ajax requests. Because of the asynchronous nature of these requests, Cypress cannot intuitively know to wait for them. You must define these routes and be able to unambiguously tell Cypress which requests you want to wait on.

Can I test the HTML <head> element?

Yes, you sure can. While executing tests in the Test Runner, you can view the entire window.document object in your open console using cy.document(). You can even make assertions on the <head> element. Check out this example.

<!DOCTYPE html>
    <meta charset="utf-8" />
    <meta http-equiv="Content-Security-Policy" content="default-src 'self'" />
    <meta name="description" content="This description is so meta" />
    <title>Test the HEAD content</title>
    <meta name="viewport" content="width=device-width, initial-scale=1" />
describe('The Document Metadata', () => {
  beforeEach(() => {

  it('looks inside the head content using `cy.document()`', () => {
    // this will yield the entire window.document object
    // if you click on DOCUMENT from the command log,
    // it will output the entire #document to the console

  // or make assertions on any of the metadata in the head element

  it('looks inside <title> tag', () => {
    cy.get('head title').should('contain', 'Test the HEAD content')

  it('looks inside <meta> tag for description', () => {
    cy.get('head meta[name="description"]').should(
      'This description is so meta'

Can I check that a form's HTML form validation is shown when an input is invalid?

You certainly can.

Test default validation error

  <input type="text" id="name" name="name" required />
  <button type="submit">Submit</button>
cy.get('input:invalid').should('have.length', 1)
cy.get('#name').then(($input) => {
  expect($input[0].validationMessage).to.eq('Please fill out this field.')

Test custom validation error

    <input type="email" id="email" name="email" />
    <button type="submit">Submit</button>
    const email = document.getElementById('email')

    email.addEventListener('input', function (event) {
      if (email.validity.typeMismatch) {
        email.setCustomValidity('I expect an email!')
      } else {
cy.get('input:invalid').should('have.length', 0)
cy.get('input:invalid').should('have.length', 1)
cy.get('[type="email"]').then(($input) => {
  expect($input[0].validationMessage).to.eq('I expect an email!')

For more examples, read the blog post HTML Form Validation in Cypress.

Can I throttle network speeds using Cypress?

You can throttle your network connection by accessing your Developer Tools Network panel. Additionally, you can add your own custom presets by selecting Custom > Add from the Network Conditions drawer.

We do not currently offer any options to simulate this during cypress run.

Can I use the new ES7 async / await syntax?

No. The Command API is not designed in a way that makes this possible. This is not a limitation of Cypress - it is a very conscious and important design decision.

Async / await is sugar around promises and Cypress commands are a mixture of both promises and streams.

If you're curious please read:

How do I select or query for elements if my application uses dynamic classes or dynamic IDs?

Don't use classes or ID's. You add data-* attributes to your elements and target them that way.

Read more about the best practices for selecting elements here.

I want to run tests only within one specific folder. How do I do this?

You can specify which test files to run during cypress run by passing a glob to the --spec flag matching the files you want to run. You should be able to pass a glob matching the specific folder where the tests are you want to run.

This feature is not available when using cypress open however.

Is there a suggested way or best practice for how I should target elements or write element selectors?

Yes. Read more about the best practices for selecting elements here.

Can I prevent Cypress from failing my test when my application throws an uncaught exception error?


By default Cypress will automatically fail tests whenever an uncaught exception bubbles up out of your app.

Cypress exposes an event for this (amongst many others) that you can listen for to either:

  • Debug the error instance itself
  • Prevent Cypress from failing the test

This is documented in detail on the Catalog Of Events page and the recipe Handling errors.

Will Cypress fail the test when an application has unhandled rejected promise?

By default no, Cypress does not listen to the unhandled promise rejection event in your application, and thus does not fail the test. You can set up your own listener though and fail the test, see our recipe Handling errors:

// register listener during cy.visit
it('fails on unhandled rejection', () => {
  cy.visit('/', {
    onBeforeLoad(win) {
      win.addEventListener('unhandledrejection', (event) => {
        const msg = `UNHANDLED PROMISE REJECTION: ${event.reason}`

        // fail the test
        throw new Error(msg)

// ALTERNATIVE: register listener for this test
it('fails on unhandled rejection', () => {
  cy.on('window:before:load', (win) => {
    win.addEventListener('unhandledrejection', (event) => {
      const msg = `UNHANDLED PROMISE REJECTION: ${event.reason}`

      // fail the test
      throw new Error(msg)


// ALTERNATIVE: register listener in every test
before(() => {
  Cypress.on('window:before:load', (win) => {
    win.addEventListener('unhandledrejection', (event) => {
      const msg = `UNHANDLED PROMISE REJECTION: ${event.reason}`

      // fail the test
      throw new Error(msg)

it('fails on unhandled rejection', () => {

Can I override environment variables or create configuration for different environments?

Yes, you can pass configuration to Cypress via environment variables, CLI arguments, JSON files and other means.

Read the Environment Variables guide.

Can I override or change the default user agent the browser uses?

Yes. You can override this with userAgent in your configuration file (cypress.json by default).

Can I block traffic going to specific domains? I want to block Google Analytics or other providers.

Yes. You can set this with blockHosts in your configuration file (cypress.json by default).

Also, check out our Stubbing Google Analytics Recipe.

How can I verify that calls to analytics like Google Analytics are being made correct?

You can stub their functions and then ensure they're being called.

Check out our Stubbing Google Analytics Recipe.

I'm trying to test a chat application. Can I run more than one browser at a time with Cypress?

We've answered this question in detail here.

Can I test a chrome extension? How do I load my chrome extension?

Yes. You can test your extensions by loading them when we launch the browser..

How can I modify or pass arguments used to launch the browser?

You use the before:browser:launch plugin event.

Can I make cy.request() poll until a condition is met?

Yes. You do it the same way as any other recursive loop.

Can I use the Page Object pattern?


The page object pattern isn't actually anything "special". If you're coming from Selenium you may be accustomed to creating instances of classes, but this is completely unnecessary and irrelevant.

The "Page Object Pattern" should really be renamed to: "Using functions and creating custom commands".

If you're looking to abstract behavior or roll up a series of actions you can create reusable Custom Commands with our API. You can also use regular ol' JavaScript functions without any of the ceremony typical with "Page Objects".

For those wanting to use page objects, we've highlighted the best practices for replicating the page object pattern.

Why do my Cypress tests pass locally but not in CI?

There are many reasons why tests may fail in CI but pass locally. Some of these include:

  • There is a problem isolated to the Electron browser (cypress run by default runs in the Electron browser)
  • A test failure in CI could be highlighting a bug in your CI build process
  • Variability in timing when running your application in CI (For example, network requests that resolve within the timeout locally may take longer in CI)
  • Machine differences in CI versus your local machine -- CPU resources, environment variables, etc.

To troubleshoot why tests are failing in CI but passing locally, you can try these strategies:

  • Test locally with Electron to identify if the issue is specific to the browser.
  • You can also identify browser-specific issues by running in a different browser in CI with the --browser flag.
  • Review your CI build process to ensure nothing is changing with your application that would result in failing tests.
  • Remove time-sensitive variability in your tests. For example, ensure a network request has finished before looking for the DOM element that relies on the data from that network request. You can leverage aliasing for this.
  • Ensure video recording and/or screenshots are enabled for the CI run and compare the recording to the Command Log when running the test locally.

Why are my video recordings freezing or dropping frames when running in CI?

Videos recorded on Continuous Integration may have frozen or dropped frames if there are not enough resources available when running the tests in your CI container. Like with any application, there needs to be the required CPU to run Cypress and record video. You can run your tests with memory and CPU logs enabled to identify and evaluate the resource utilization within your CI.

If you are experiencing this issue, we recommend switching to a more powerful CI container or provider.

What can I do if my tests crash or hang on CI?

As some users have noted, a longer test has a higher chance of hanging or even crashing when running on CI. When a test runs for a long period of time, its commands and the application itself might allocate more memory than available, causing the crash. The exact risk of crashing depends on the application and the available hardware resources. While there is no single time limit that would solve this problem, in general we recommend splitting spec files to run in under one minute each. You can read the blog post Make Cypress Run Faster by Splitting Specs to learn how to split a spec file.

You can further split individual long-running tests. For example, you can verify parts of the longer user feature in the separate tests as described in Split a very long Cypress test into shorter ones using App Actions.

How can I parallelize my runs?

You can read more about parallelization here.

Can I run a single test or group of tests?

You can run a group of tests or a single test by placing an .only on a test suite or specific test.

You can run a single test file or group of tests by passing the --spec flag to cypress run.

How do I test uploading a file?

It is possible to upload files in your application but it's different based on how you've written your own upload code. Many people had success by using the community plugin cypress-file-upload. This plugin adds a custom child command .attachFile that you call from the test.

// attaches the file cypress/fixtures/data.json

You can read more about uploading files in this issue.

What is the projectId for?

The projectId is a 6 character string that helps identify your project once you've set up your tests to record. It's generated by Cypress and typically is found in your configuration file (cypress.json by default) file.

  "projectId": "a7bq2k"

For further detail see the Identification section of the Dashboard Service docs.

What is a Record Key?

A Record Key is a GUID that's generated automatically by Cypress once you've set up your tests to record. It helps identify your project and authenticate that your project is even allowed to record tests.

You can find your project's record key inside of the Settings tab in the Test Runner.

Record Key in Configuration Tab

For further detail see the Identification section of the Dashboard Service docs.

How do I check that an email was sent out?

  1. If your application is running locally and is sending the emails directly through an SMTP server, you can use a temporary local test SMTP server running inside Cypress Test Runner. Read the blog post "Testing HTML Emails using Cypress" for details.
  2. If your application is using a 3rd party email service, or you cannot stub the SMTP requests, you can use a test email inbox with an API access. Read the blog post "Full Testing of HTML Emails using SendGrid and Ethereal Accounts" for details.

Cypress can even load the received HTML email in its browser to verify the email's functionality and visual style:

The test finds and clicks the Confirm registration button
  1. You can use a 3rd party email service that provides temporary email addresses for testing. Some of these services even offer a Cypress plugin to access emails.

How do I wait for multiple requests to the same url?

You should set up an alias (using .as()) to a single cy.intercept() that matches all of the XHRs. You can then cy.wait() on it multiple times. Cypress keeps track of how many matching requests there are.

cy.wait('@getUsers') // Wait for first GET to /users/
cy.get('#list>li').should('have.length', 10)
cy.wait('@getUsers') // Wait for second GET to /users/
cy.get('#list>li').should('have.length', 20)

How do I seed / reset my database?

You can use cy.request(), cy.exec(), or cy.task() to talk to your back end to seed data.

You could also stub requests directly using cy.intercept() which avoids ever even needing to fuss with your database.

How do I test elements inside an iframe?

We have an open proposal to expand the APIs to support "switching into" an iframe and then back out of them.

How do I preserve cookies / localStorage in between my tests?

By default, Cypress automatically clears all cookies before each test to prevent state from building up.

You can preserve specific cookies across tests using the Cypress.Cookies api:

// now any cookie with the name 'session_id' will
// not be cleared before each test runs
  preserve: 'session_id',

You cannot currently preserve localStorage across tests and can read more in this issue.

Some of my elements animate in; how do I work around that?

Oftentimes you can usually account for animation by asserting .should('be.visible') or another assertion on one of the elements you expect to be animated in.

// assuming a click event causes the animation
cy.get('.element').click().should('not.have.class', 'animating')

If the animation is especially long, you could extend the time Cypress waits for the assertion to pass by increasing the timeout of the previous command before the assertion.

cy.get('button', { timeout: 10000 }) // wait up to 10 seconds for this 'button' to exist
  .should('be.visible') // and to be visible

  .click({ timeout: 10000 })
  .should('not.have.class', 'animating')
// wait up to 10 seconds for the .element to not have 'animating' class

However, most of the time you don't even have to worry about animations. Why not? Cypress will automatically wait for elements to stop animating prior to interacting with them via action commands like .click() or .type().

Cypress does not and may never have multi-tab support for various reasons.

Luckily there are lots of clear and safe workarounds that enable you to test this behavior in your application.

Read through the recipe on tab handling and links to see how to test anchor links.

Can I dynamically test multiple viewports?

Yes, you can. We provide an example here.

Can I run the same tests on multiple subdomains?

Yes. In this example, we loop through an array of urls and make assertions on the logo.

const urls = ['', '']

describe('Logo', () => {
  urls.forEach((url) => {
    it(`Should display logo on ${url}`, () => {
      cy.get('#logo img').should('have.attr', 'src').and('include', 'logo')
Command Log multiple urls

How do I require or import node modules in Cypress?

The code you write in Cypress is executed in the browser, so you can import or require JS modules, but only those that work in a browser.

You can require or import them as you're accustomed to. We preprocess your spec files with webpack and Babel.

We recommend utilizing one of the following to execute code outside of the browser. Furthermore, you can use your own Node version during code excecution by setting the nodeVersion in your configuration.

Check out the "Node Modules" example recipe.

Is there a way to give a proper SSL certificate to your proxy so the page doesn't show up as "not secure"?

No, Cypress modifies network traffic in real time and therefore must sit between your server and the browser. There is no other way for us to achieve that.

Is there any way to detect if my app is running under Cypress?

You can check for the existence of window.Cypress, in your application code.

Here's an example:

if (window.Cypress) {
  // we are running in Cypress
  // so do something different here
  window.env = 'test'
} else {
  // we are running in a regular ol' browser

Do you allow before, beforeEach, after, or afterEach hooks?

Yes. You can read more here.

I tried to install Cypress in my CI, but I get the error: EACCES: permission denied.

First, make sure you have Node installed on your system. npm is a Node package that is installed globally by default when you install Node and is required to install our cypress npm package.

Next, you'd want to check that you have the proper permissions for installing on your system or you may need to run sudo npm install cypress.

Is there a way to test that a file got downloaded? I want to test that a button click triggers a download.

There are a lot of ways to test this, so it depends. You'll need to be aware of what actually causes the download, then think of a way to test that mechanism.

If your server sends specific disposition headers which cause a browser to prompt for download, you can figure out what URL this request is made to, and use cy.request() to hit that directly. Then you can test that the server send the right response headers.

If it's an anchor that initiates the download, you could test that it has the right href property. As long as you can verify that clicking the button is going to make the right HTTP request, that might be enough to test for.

Finally, if you want to really download the file and verify its contents, see our File download recipe.

In the end, it's up to you to know your implementation and to test enough to cover everything.

Is it possible to catch the promise chain in Cypress?

No. You cannot add a .catch error handler to a failed command. Read more about how the Cypress commands are not Promises

Is there a way to modify the screenshots/video resolution?

There is an open issue for more easily configuring this.

You can modify the screenshot and video size when running headlessly with this workaround.

Does Cypress support ES7?

Yes. You can customize how specs are processed by using one of our preprocessor plugins or by writing your own custom preprocessor.

Typically you'd reuse your existing Babel and webpack configurations.

How does one determine what the latest version of Cypress is?

There are a few ways.

  • The easiest way is probably to check our changelog.
  • You can also check the latest version here.
  • It's also always in our repo.

Is there an ESLint plugin for Cypress or a list of globals?

Yes! Check out our ESLint plugin. It will set up all the globals you need for running Cypress, including browser globals and Mocha globals.

When I visit my site directly, the certificate is verified, however the browser launched through Cypress is showing it as "Not Secure". Why?

When using Cypress to test an HTTPS site, you might see a browser warning next to the browser URL. This is normal. Cypress modifies the traffic between your server and the browser. The browser notices this and displays a certificate warning. However, this is purely cosmetic and does not alter the way your application under test runs in any way, so you can safely ignore this warning. The network traffic between Cypress and the backend server still happens via HTTPS.

See also the Web Security guide.

Is there an option to run Cypress in CI with Developer Tools open? We want to track network and console issues.

No. There is not currently a way to run Cypress in cypress run with Developer Tools open. Refer to this issue if you'd like this feature.

You may try running the tests locally and select the Electron browser, that is as close as you will get with Developer Tools open and replicating the environment that was run during cypress run.

How do I run the server and tests together and then shutdown the server?

To start the server, run the tests and then shutdown the server we recommend these npm tools.

Can I test my Electron app?

Testing your Electron app will not 'just work', as Cypress is designed to test anything that runs in a browser and Electron is a browser + Node.

That being said, we use Cypress to test our own Desktop app's front end - by stubbing events from Electron. These tests are open source so you can check them out here.

I found a bug! What do I do?

  • Search existing open issues, it may already be reported!
  • Update Cypress. Your issue may have already been fixed.
  • open an issue. Your best chance of getting a bug looked at quickly is to provide a repository with a reproducible bug that can be cloned and run.

What are your best practices for organizing tests?

We see organizations starting with Cypress by placing end-to-end tests in a separate repo. This is a great practice that allows someone on the team to prototype a few tests and evaluate Cypress within minutes. As the time passes and the number of tests grows, we strongly suggest moving end-to-end tests to live right alongside your front end code. This brings many benefits:

  • engages developers in writing end-to-end tests sooner
  • keeps tests and the features they test in sync
  • tests can be run every time the code changes
  • allows code sharing between the application code and the tests (like selectors)

What is the right balance between custom commands and utility functions?

There is already a great section in Custom Commands guide that talks about trade-offs between custom commands and utility functions. We feel reusable functions in general are a way to go. Plus they do not confuse IntelliSense like custom commands do.

Can I print the list of commands from a test in the terminal?

If a test fails, Cypress takes a screenshot image, but does not print the list of commands in the terminal, only the failed assertion. There is a user space plugin cypress-failed-log that saves a JSON file with all commands from a failed test.

Can my tests interact with Redux / Vuex data store?

Usually your end-to-end tests interact with the application through public browser APIs: DOM, network, storage, etc. But sometimes you might want to make assertions against the data held inside the application's data store. Cypress helps you do this. Tests run right in the same browser instance and can reach into the application's context using cy.window. By conditionally exposing the application reference and data store from the application's code, you can allow the tests to make assertions about the data store, and even drive the application via Redux actions.

How do I spy on console.log?

To spy on console.log you should use cy.stub().

cy.visit('/', {
  onBeforeLoad(win) {
    cy.stub(win.console, 'log').as('consoleLog')

cy.get('@consoleLog').should('be.calledWith', 'Hello World!')

Also, check out our Stubbing console Receipe.

How do I use special characters with cy.get()?

Special characters like /, . are valid characters for ids according to the CSS spec.

To test elements with those characters in ids, they need to be escaped with CSS.escape or Cypress.$.escapeSelector.

<!DOCTYPE html>
<html lang="en">
    <div id="Configuration/Setup/">Hello World</div>
it('test', () => {
    'Hello World'

  ).contains('Hello World')

Note that cy.$$.escapeSelector() doesn't work. cy.$$ doesn't refer to jQuery. It only queries DOM. Learn more about why

Can I use Cypress to test charts and graphs?

Yes. You can leverage visual testing tools to test that charts and graphs are rendering as expected. For more information, check out the Visual Testing guide and the following blog posts.

Why doesn't the instanceof Event work?

It might be because of the 2 different windows in Cypress Test Runner. For more information, please check the note here.

Can I use Cucumber to write tests?

Yes, you can. You can write feature files containing Cucumber scenarios and then use Cypress to write your step definitions in your spec files. A special preprocessor then converts the scenarios and step definitions into "regular" JavaScript Cypress tests.

Can I test Next.js sites using Cypress?

Yes, absolutely. See an example in the next-and-cypress-example repository where we show how to instrument the application's source code to get code coverage from tests. You can learn how to set good Cypress tests for a Next.js application in this tutorial.

Can I test Gatsby.js sites using Cypress?

Yes, as you can read in the official Gatsby docs. You can also watch the "Cypress + Gatsby webinar" recording and browse the webinar's slides.

Can I test React applications using Cypress?

Yes, absolutely. A good example of a fully tested React application is our Cypress RealWorld App and TodoMVC Redux App. You can even use React DevTools while testing your application, read The easiest way to connect Cypress and React DevTools. If you really need to select React components by their name, props, or state, check out cypress-react-selector.

Finally, you might want to check out the React Component Testing adaptor that allows you to test your React components right inside Cypress.

Can I check the GraphQL network calls using Cypress?

Yes, by using the newer API command cy.intercept() as described in the Smart GraphQL Stubbing in Cypress post or by utilizing the cypress-graphql-mock plugin.

Can Cypress be used for model-based testing?

Yes, for example see this webinar hosted by Curiosity Software. In addition, since our Real World App (RWA) is implemented using XState model state library, we are looking for ways to make model-based testing simpler and more powerful. Read Access XState from Cypress Test for our start.

Can Cypress be used for performance testing?

Cypress is not built for performance testing. Because Cypress instruments the page under test, proxies the network requests, and tightly controls the test steps, the Test Runner adds its own overhead. Thus, the performance numbers you get from Cypress tests are slower than "normal" use. Still, you can access the native window.performance object and grab the page time measurements, see the Evaluate performance metrics recipe. You can also run Lighthouse audit straight from Cypress via cypress-audit community plugin.

Can Cypress test WASM code?

Yes, read the blog post Cypress WASM Example. We welcome more user feedback to make WASM testing simpler.

Can I use Cypress to document my application?

End-to-end tests are an excellent way to keep your application's documentation accurate and up-to-date. Read Cypress Book blog post, and take a look at cypress-movie project.

Can I use Jest snapshots?

While there is no built-in snapshot command in Cypress, you can make your own snapshot assertion command. Read how to do so in our blog post End-to-End Snapshot Testing. We recommend using the 3rd-party module cypress-plugin-snapshots. For other snapshot plugins, search the Plugins page.

Can I use Testing Library?

Absolutely! Feel free to add the @testing-library/cypress to your setup and use its methods like findByRole, findByLabelText, findByText, findByTestId, and others to find the DOM elements.

The following example comes from the Testing Library's documentation

cy.findByRole('button', { name: /Jackie Chan/i }).click()
cy.findByRole('button', { name: /Button Text/i }).should('exist')
cy.findByRole('button', { name: /Non-existing Button Text/i }).should(

cy.findByLabelText(/Label text/i, { timeout: 7000 }).should('exist')
