Playwright Regression Testing (TypeScript)

Strategy and best practices for automated regression testing of web applications using Playwright with TypeScript.

Activation: This skill is triggered when working with regression test strategy, test suite selection, test prioritization, CI/CD pipeline testing, flaky test management, test sharding, or optimizing test execution for web applications using Playwright.

When to Use This Skill

• Plan regression suites with risk-based and change-based test selection
• Organize tests into tiers (smoke, sanity, selective, full regression)
• Optimize execution with parallelization, sharding, and time-budget strategies
• Integrate with CI/CD using GitHub Actions pipelines
• Manage flaky tests with quarantine, retry policies, and root cause tracking
• Monitor suite health with execution time, flake rate, and detection metrics
• Select tests after changes using git diff analysis and impact mapping
