Automated tests
This document describes how to run the automated tests and what the different tests cover.
Unit tests
All packages in packages/
have unit tests. To run them:
npm run test
The main test runner is Vitest. vscode-css-languageservice
uses Mocha.
Unit tests typically cover either a utility function or a language feature such as doHover
. For language features the tests are typically split in several files, each focusing on part of the functionality of the language feature.
End-to-end tests
The Visual Studio Code extension includes end-to-end tests. To run them:
npm run test:e2e
It also includes end-to-end tests for the web extension. To run them:
npm run test:web
The end-to-end tests have some overlap with the unit tests for language features, but are useful to confirm the communication between client and server works as expected.
Run all tests
A convenience script lets you run all unit tests and end-to-end tests:
npm run test:all
