CKEditor 5 testing environment

Testing environment for CKEditor 5. It's based on Karma and webpack and it's normally used in the CKEditor 5 development environment. Read more about CKEditor 5's testing environment.

More information about development tools packages can be found at the following URL: https://github.com/ckeditor/ckeditor5-dev.

Usage

First, you need to install the package:

npm i --save-dev @ckeditor/ckeditor5-dev-tests

An example npm task to test CKEditor 5 packages (used e.g. in https://github.com/ckeditor/ckeditor5) can look like this:

{
  "scripts": {
      "test": "node ./node_modules/.bin/ckeditor5-dev-tests-run-automated",
      "manual": "node ./node_modules/.bin/ckeditor5-dev-tests-run-manual"
  }
}

If you encounter problems with big test folders pass --max_old_space_size=4096 option to node runner:

{
  "scripts": {
      "test": "node --max_old_space_size=4096 ./node_modules/.bin/ckeditor5-dev-tests-run-automated"
  }
}

You can also use the bin script for testing a package:

# For running all the tests (for the current package and all dependencies).
./node_modules/.bin/ckeditor5-dev-tests --files=*

# For running tests in the current package.
./node_modules/.bin/ckeditor5-dev-tests

CLI options

• browsers - Browsers which will be used to run the tests. Also available as an alias: -b.
• coverage - Whether to generate code coverage. Also available as an alias: -c.
• debug - Allows specifying custom debug flags. For example, the --debug engine option uncomments the // @if CK_DEBUG_ENGINE // lines in the code. By default --debug is set to true even if you did not specify it. This enables the base set of debug logs (// @if CK_DEBUG //) which should always be enabled in the testing environment. You can completely turn off the debug mode by setting the --debug false option or --no-debug.
• files - Package names, directories or files to tests. Also available as an alias: -f. Read more about this option in the Rules for using the --files option section.
• language – Specifies a language that will be used while building tests. By default it is en.
• production - Run strictest set of checks. E.g. it fails test run when there are console calls or DOM leaks.
• repositories (-r) - Specifies names of repositories containing packages that should be tested. Those repositories should be cloned into the external/ directory in the root directory of the project. It's a shortcut of the --files option as these repository packages' names will be read by the tool automatically.
• reporter - Mocha reporter – either mocha (default) or dots (less verbose one).
• server - Whether to run the server without opening any browser.
• source-map - Whether to generate the source maps. Also available as an alias: -s.
• verbose - Whether to informs about Webpack's work. Also available as an alias: -v.
• watch - Whether to watch the files and executing tests whenever any file changes. Also available as an alias: -w.

Examples

Test the ckeditor5-enter and ckeditor5-paragraph packages and generate code coverage report:

$ npm t -- -c --files=enter,paragraph

Run tests/view/**/*.js tests from ckeditor5-engine and rerun them once any file change (the watch mode):

$ npm t -- -w --files=engine/view/

Test specified files in ckeditor5-basic-styles on two browsers (Chrome and Firefox):

$ npm t -- --browsers=Chrome,Firefox --files=basic-styles/bold,basic-styles/italic

Test all installed packages:

$ npm t -- --files=*

Test all installed packages except one (or more):

$ npm t -- --files='!(engine)'
$ npm t -- --files='!(engine|ui)'

IDE integrations

The CKEditor 5 can be integrated with IDEs via integrations.

Currently only the IntelliJ based IDEs are supported (WebStorm, PHPStorm, etc). Detailed information are provided in bin/intellijkarmarunner/README.md.
