What's New

Turn off the Command Log in the Test Runner when debugging performance issues. The Command Log can be hidden by passing the CYPRESS_NO_COMMAND_LOG=1 environmental variable during cypress open or cypress run to be used as a tool to debug performance issues.

As always, bug fixes and improvements were made. View the full list in the 5.4.0 changelog.

What’s New

Firefox support is out of beta! Firefox 80 and newer are officially stable when used with Cypress. The firefoxGcInterval workaround is no longer needed unless testing versions of Firefox older than 80.

As always, bug fixes and improvements were made, including a few fixes to experimental network stubbing. View the full list in the 5.3.0 changelog.

New Features:

Support for shadow DOM is no longer experimental (which also means that we've removed the experimentalShadowDomSupport configuration flag). Now, by using the configuration option includeShadowDOM to enable shadow DOM, you'll be able to query globally, per-suite, per-test, or programmatically.

Ensure redirects are followed with experimental network stubbing. We recently introduced experimental network stubbing via cy.route2(). Now, we've added a followRedirect option that will ensure redirects are followed before resolving the req.reply callback. Additionally, we've added the capability to specify delayMs and throttleKbps when stubbing static responses.

As always, bug fixes and improvements were made and you can see the full list in the 5.2.0 changelog.

However, if you happened to experience the issue with test retries that caused Cypress to hang in run mode with certain assertions, that has been fixed.

And if you experienced a performance issue which led to CPU bottlenecking during Cypress runs, that too has now been fixed.

What's New

Introducing experimental full network stubbing support. When experimentalNetworkStubbing is enabled, the cy.route2 command is available. By using cy.route2(), your tests can intercept, modify, and wait on any type of HTTP request originating from your app, including XMLHttpRequests, fetch requests, beacons and subresources (like iframes and scripts).

Outgoing HTTP requests can be modified before reaching the destination server, and the HTTP response can be intercepted as well before it reaches the browser.

Get specific with your event triggers. cy.trigger() now accepts an eventConstructor option in case you want to specify the type of event that you want to trigger (e.g. MouseEvent or KeyboardEvent).

For example - cy.get('button').trigger('mouseover', { eventConstructor: 'MouseEvent' })

We also fixed several bugs and made a small handful of dependency updates. See the full changelog for 5.1.0 >

New Features

Cypress 5.0 has native support for test retries. Test retries are off by default. However, they can be configured using the new retries configuration option which allows you to set the number of times to retry a failing test.

We’ve improved clicking with modifiers. Now, .click(), .dblclick(), and .rightclick() accept options altKey, ctrlKey, metaKey, and shiftKey to hold down key combinations while clicking.

We now allow you to disable DOM snapshots for stubs and spies. You can chain .snapshot() off of cy.stub() and cy.spy() to disable snapshots during those commands. For example: cy.stub().snapshot(false).

Breaking Changes

Ready to upgrade? Cypress 5.0 contains some breaking changes. We put together a detailed Cypress 5.0 Migration Guide for a full breakdown on how to update your code to support 5.0.

We’ve renamed Cypress.Cookies.defaults() whitelist to preserve to better reflect its behavior. We also renamed the blacklistHosts configuration to blockHosts and cy.server() whitelist option to ignore for the same reason.

Because Cypress 5.0 has test retries built in natively (although they are disabled by default), we have deprecated the cypress-plugin-retries plugin. You will see an error message if you have the plugin still installed after upgrading to Cypress 5.0.

We made adding the sameSite property to objects yielded by cy.setCookie(), cy.getCookie(), and cy.getCookies() the default. As a result, the experimentalGetCookiesSameSite configuration has been removed.

If you have file paths with a question mark ? in them, Cypress no longer supports those.

Libgbm-dev is now a requirement to run Cypress on Linux.

Cypress now requires TypeScript 3.4+

Installing Cypress on your system now requires node.js 10+

Several bug fixes and improvements were made as well. See the full changelog for 5.0.0 >

New Features

• You can now control whether screenshots are automatically taken on test failure during  cypress run by setting screenshotOnRunFailure in your configuration.
• The pluginsFile now has access to a readonly version property within the config object that returns the current Cypress version being run. This will allow plugins to better target specific Cypress versions.
• During cypress open, you can now run a subset of all specs by entering a text search filter and clicking ‘Run n tests’.

What's New

Better time traveling with improvements to cy.clock(). If you've ever used cy.clock() to control the time of the world within your app, you know that historically you needed to provide an epoch time number (and you may have tried to pass a Date object and realized that we would just ignore it). But now, you can provide either a Date object or an epoch time number AND we won't just ignore it, we’ll convert it to the Number and it’ll work just fine.

Do or don’t ensureScrollability. We also made it so that you can now pass an ensureScrollability: false option to .scrollTo() to skip checking whether the element is scrollable.

We also fixed several bugs and made several (specifically 10) dependency updates. See the full changelog for 4.11.0 >

What’s New

Edit tests more easily with the Open in IDE button. Now, when hovering over a test in the Test Runner you’ll see the 'Open in IDE' link. Clicking it will open the spec in your code editor so you can edit your tests more easily.

Get better insight into the hooks running around your tests. If you’re using the before, beforeEach, after, and afterEach hook definitions to set conditions that you want to run before or after a set of tests (or before or after each test), those will now display separately in the Test Runner’s Command Log if they are defined in separate hook definitions.

And, if you need to open or edit those specs in your IDE you’ll see that ‘Open in IDE’ link when hovering, and you can click to open that spec file directly.

We also fixed several bugs and made some minor UI improvements to the Test Runner. See the full changelog for 4.10.0 >

The Cypress Real World App (RWA) is now available as an open-sourced project on Github. The RWA is a sample payment application that we have often used for demonstrating real world usage of Cypress testing methods, patterns, best practices and workflows.

Now anyone can use the Cypress Real World App to learn, experiment, tinker, train and practice testing with Cypress. Learn more >
