tsds-web-test-runner

This package is an internal command adapter for running browser tests through ts-dev-stack, not a standalone end-user command.

Install the parent CLI and this adapter locally so browser installation uses the adapter's resolved Playwright version.

The default configuration runs Chromium, Firefox and WebKit. Their matching Playwright binaries and OS dependencies must be installed before running tests. The browser installation step below uses the locally installed Playwright CLI. Provide browser tests using Mocha's describe and it under test/**/*.test.{ts,tsx,jsx,mjs} before running the test command.

npm install --save-dev ts-dev-stack tsds-web-test-runner
npm exec --no -- playwright install --with-deps
npm exec --no -- tsds test:browser

Repeat browser installation after changing the resolved Playwright version. If you set PLAYWRIGHT_BROWSERS_PATH, use the same absolute path for installation and execution. See Playwright browser management and repository test setup.

Pass the Web Test Runner arguments after test:browser, for example npm exec --no -- tsds test:browser --config wtr.config.mjs.

Without an explicit test path, it runs test/**/*.test.{ts,tsx,jsx,mjs}. Add --dry-run to check command selection without opening a browser.

Starting with the planned 1.21.0 release, the adapter attempts to restore its temporary installation link after setup or test failure. A sole operation or restoration failure is reported directly. If both fail, the callback receives an Error whose errors array contains the operation error first and the restoration error second.
