Cypress Test Runner v5.3.0

Released 9.28.2020

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.

Cypress Test Runner v5.2.0

Released 9.15.2020

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.

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.

Now, installing Cypress pre-releases no longer requires setting thee CYPRESS_BINARY_INSTALL environment variable.

Bug Fixes and Improvements

As per usual, several bugs were fixed with this release. Here are the highlights.

You might have experienced a performance issue which led to CPU bottlenecking during Cypress runs. That has now been fixed.

There was an issue with test retries that caused Cypress to hang (as in to stop running tests) in run mode with certain assertions. This has been fixed.

There was an issue with cy.getCookie() where assertions would be called twice. That has now been fixed.

There were two bugs related to shadow DOM that have been fixed. One, where using cy.contains() within a shadow root wouldn't yield the correct element and one where wearying the shadow DOM in a cy.within() callback would throw the error root.getRootNode is not a function.

You may have noticed a bug when using cy.type() with the special characters {moveToStart}/{moveToEnd} wherein the cursor would move only the the start or end of the current line rather than of the entire text editable when typing in a contenteditable element. This has now been fixed.

Cypress Test Runner v5.1.0

Released 9.1.2020


Cypress 5.1.0 introduces 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.

Check out the cy.route2() docs for more info on how to enable this experiment.

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' })

Several bugs were fixed. Here are some of them (check the Changelog for the full list).

When a user exceeds the test limits of their free Cypress Dashboard plan, they’ll now see a warning message in the stdout.

You can now specify retries as a TestOptions type.

Types for specType field on Cypress.spec have been added.

There was a typo in the Typescript definitions where it said TestCptions rather than TestOptions (whoops) and now this has been fixed.

It was possible to run a never ending test accidentally when nesting hooks within other hooks and so now that has been fixed.

Cypress now resolves and loads tsconfig.json for TypeScript projects starting from the plugins directory.

There was an issue where, if npm config’s noproxy was set, unexpected behavior could occur. That has now been fixed.

There was an issue where test would unexpectedly fail with a “can’t resolve ‘async_hooks’” error. That has now been fixed.

There was an issue where return values from blob utils were mistaken for promises and could cause errors. That has now been fixed.

Now, cy.trigger() includes the view property in the event object when that is appropriate.

Cypress Test Runner v5.0.0

Released 8.18.2020

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.

Here are some of the breaking changes to be aware of:

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+

Bug Fixes and Improvements

If you’ve ever seen the error Cannot set property 'err' of undefined incorrectly when rerunning tests in the Test Runner, you won’t anymore because it is fixed. 

If you’ve ever seen the Cannot read property ‘isAttached’ of undefined error during cypress run on Firefox versions >= 75, you won’t anymore because it is fixed.

If you’ve ever seen the error Maximum call stack size exceeded when calling scrollIntoView on an element in the shadow dom you won’t anymore because it is fixed.

Cypress environment variables that accept arrays as their value will now properly evaluate as arrays. 

Elements that have display: inline will no longer be considered hidden if they have child elements within them that are visible.

If a test fails in an afterEach or beforeEach hook after the hook has already passed, screenshots will now be correctly taken.

Speaking of screenshots, Cypress will no longer report screenshots overwritten in a cy.screenshot() onAfterScreenshot option as a unique screenshot. 

Additionally, taking screenshots will no longer fail when the screenshot names are too long for the filesystem to accept. Go ahead, go crazy with those screenshot names. 

Now Cypress will correctly remember the “last used browser” during cypress open if a non-default-channel browser was selected.

reporterStats will now correctly show the number of passed and failed tests when a test passes but the afterEach fails. 

The Developer Tools menu will now always display in Electron when switching focus from Specs to the Test Runner.
