Testing

Running tests

Before running make sure to compile tests with compile or watch scripts.

To run tests on theia run:

npm run test

This will run all CI enabled tests.

If you want to run all tests for a particular Theia extension, execute the following command from the root:

npx lerna run test --scope @theia/extension-name

Add the following npm script to the package.json of the desired Theia extension, if you would like to enable the watch mode for the tests.

  "test:watch": "theiaext test:watch"

After editing the package.json you can run the tests in watch mode with:

npx lerna run test:watch --scope @theia/extension-name

The test directory structure is as follows:

src/node/foo.ts: Code to be tested.
src/node/foo.spec.ts: Unit tests for foo.ts.
src/node/test/test-helper.ts: Any mocks, fixture or utility test code goes here.
src/node/foo.slow-spec.ts: Any slow running tests such as integration tests should be labeled as such so that they can be excluded.
src/browser/foo.ui-spec.ts: UI tests.
test-resources: Any resources needed for the tests like configuration files or scripts.
test-resources/ui: Resources for UI testing.
test-resources/slow: Resources for slow running tests.

Unit tests named as foo.spec.ts will be published since they're also for documentation purposes.
