How do I install test coverage for Playwright, Selenium, or Cypress?
Install the TestMap agent npm package for your framework: @appsurify-testmap/rrweb-playwright-plugin, rrweb-selenium-plugin, or rrweb-cypress-plugin. Initialize the agent in a beforeEach/afterEach hook. Run your suite. Upload the coverage JSON to app.testmap.io via dashboard or CI (GitHub Action: appsurify/testmap-upload-action@v1). The heatmap renders in under 10 minutes.
