IntelliJ Cypress integration plugin

Integrates Cypress.io under the common Intellij test framework.

Compatibility

As the plugin depends on JavaLanguage and NodeJS plugins, so it requires a commercial version of IDEA (Ultimate, WebStorm etc)

Install

Plugin can be installed from the Jetbrains Marketplace. Open 'Settings/Preferences -> Plugins' menu item and type 'Cypress' in the search bar. See here for details. Please note that base and Pro versions are not expected to run together so you should disable or uninstall one of them to use the other.

Usage

Brief video overview: https://www.youtube.com/watch?v=1gjjy0RQeBw

Test run configurations

Plugin introduces a dedicated Cypress run configuration type You can create a run config from either file view (directory, spec file) or directly from the code

file view code view

Notice that cypress-intellij-reporter introduces mocha dependency that enables the mocha test framework in IDEA automatically. So please do not confuse Cypress and Mocha run types:

Running tests

Simply start your configuration and take a deep breath. You can watch test status live on the corresponding tab:

You can navigate from a test entry in the test tab to the source code of this test just by clicking on it.

Pro version also supports running Cucumber-Cypress tests.

Runner limitations:

  1. No rerun failed tests only feature because Cypress is unable to run tests defined by a grep pattern
  2. Run a single test feature is implemented by modifying the sources on the fly and mark the test with .only modifier automatically. So it may work incorrectly when a test spec already contains '.only' tests

Debugging tests (Pro version only)

Cypress Support Pro plugin is able to debug Cypress test execution.

Video overview: https://www.youtube.com/watch?v=FIo62E1OMO0

It supports all the common IDE debug features: step-by-step execution, run to cursor, variable examining, expression evaluation, breakpoints (including conditional), etc.
It works for both headed and headless modes as well as in the interactive mode

Debugger limitations:

  1. Firefox is not currently supported.
  2. In some rare cases IDE can't map sources correctly so breakpoints will not hit in this case. Use debugger statement to suspend the execution
  3. IDE need some time (usually less than a second) to attach breakpoints to Chrome. So your breakpotins could not be hit when test case executed fast.
  4. Ansynchronous Cypress commands cannot be debugged as they would be synchrounous. See here for details and workarounds.

Built-In test recorder (Pro version only)

Cypress Support Pro v. 1.5+ can record UI actions and insert generated code directly into the testcase. At the Cypress Runner side, the recorder UI looks like this:

A video overview: https://youtu.be/FgnHYwmguFI

It has pluggable architecture, so the user can upload her own recorder plugin for the event capturing and code generation. Refer to this wiki page for more information about Recorder API

By default, it uses the plugin available here: script/recorder.js. Feel free to copy it localy and modify for your needs.

Fast test restart (Pro version only)

Starting version 1.2.1, plugin is able to reuse a running Cypress instance to restart the test fast.
First, you need to start test either with --no-exit option or in the interactive mode. Subsequent test runs will reuse the running browser instance.
Uncheck 'Allow parallel run' box in the run configuration to disable this feature.

Fast test restart limitations:

Cypress does not reflect code changes when run in non-interactive mode by design, see here

Autocomplete and navigation to the source (Pro version only)

Plugin adds autocomplete contribution for the following elements:

  1. Alias references inside cy.get() and cy.wait()
  2. Fixture references inside cy.fixture() and cy.route(..., 'fx:')
  3. Custom cy commands (in JS code only, use type definitions for TypeScript)

Also, all of those elements support navigation to the source by clicking on a reference

See it in action: https://youtu.be/WR5ywX01YbQ

Autocomplete background and limitations

  1. Suggested alias references are not guaranteed to be available in runtime due to the dynamic nature of JS language.
  2. Plugin searches available fixtures using settings from the cypress.json configuration. Default values are used if no configuration file found.
  3. Plugin makes a list of available custom cy commands by looking for Cypress.Commands.add function references within the project

Opening test screenshot from the test tree view

Plugin has a shortcut action to open test screenshot from the test tree view:

If a test holds screenshots in the folder, action will either suggest selecting from the list or pick up the latest screenshot.

This behavior can be configured in the settings:

Running Cucumber-Cypress tests (Pro version only)

Starting from version 1.6, the plugin can start a cucumber test.

The exectuion depends on the cypress-cucumber-preprocessor so you need to add the following dependency to your project:

npm install --save-dev cypress-cucumber-preprocessor

To start a single scenario, the plugin will automatically add (and remove at the end) a @focus tag.
