Web Test Runner Core

Core package for Web Test Runner. Manages running the tests. Has a modular architecture, delegating most of the work to the separate parts and implementations.

See @web/test-runner for a default implementation and CLI for the test runner.

Browser launchers

Browser launchers boot up and control a browser instance. Implementations:

• @web/test-runner-chrome
• @web/test-runner-puppeteer
• @web/test-runner-playwright
• @web/test-runner-selenium
• @web/test-runner-browserstack

Read more here to learn about creating your own browser launcher.

Test frameworks

Test frameworks run the actual tests in the browser. Web test runner relies on existing test frameworks. Implementations:

• @web/test-runner-mocha

Read more here to learn more about setting up a custom test reporter.

Reporters

Reporters report test results and/or progress. The CLI ships a default reporter. Implementations:

• @web/test-runner-cli

Read more here to learn more about using the browser library without a testing framework, or to implement your own testing framework.

Servers

The server serves the test code and files and communicates with the browser, returning configuration and receiving test results. Implementations:

• @web/test-runner-server

Read more here to learn about creating your own test runner server.
