    Web Test Runner

    Test runner for web applications.

    👉   Headless browsers with Puppeteer, Playwright, or Selenium.
    🚧   Reports logs, 404s, and errors from the browser.
    🔍   Debug opens a real browser window with devtools.
    📦   Mock es modules using Import Maps.
    🔧   Exposes browser properties like viewport size and dark mode.
      Runs tests in parallel and isolation.
    👀   Interactive watch mode.
    🏃   Fast development by rerunning only changed tests.
    🚀   Powered by esbuild and rollup plugins

    See our website for full documentation.

    Installation

    Install the web test runner:

    npm i --save-dev @web/test-runner
    

    Basic commands

    Do a single test run:

    web-test-runner test/**/*.test.js --node-resolve
    wtr test/**/*.test.js --node-resolve
    

    Run in watch mode, reloading on file changes:

    web-test-runner test/**/*.test.js --node-resolve --watch
    wtr test/**/*.test.js --node-resolve --watch
    

    Run with code coverage profiling (this is slower):

    web-test-runner test/**/*.test.js --node-resolve --coverage
    wtr test/**/*.test.js --node-resolve --coverage
    

    Transform JS to a compatible syntax based on user agent:

    web-test-runner test/**/*.test.js --node-resolve --esbuild-target auto
    wtr test/**/*.test.js --node-resolve --esbuild-target auto
