Automation Testing

sign in to track

Automation testing uses scripts and tools to execute test cases, compare actual outcomes with expected results, and report findings — without human intervention during execution. It is the engine behind continuous quality in modern CI/CD pipelines.

◈Key Points

  • Automate the repeatable, high-value, high-risk, and regression-prone scenarios first.
  • The Test Automation Pyramid: Unit tests (fast, cheap) → Integration → E2E (slow, expensive).
  • Key tools: Playwright, Cypress, Selenium for UI; RestAssured, Postman/Newman for API; JUnit/PyTest for unit.
  • Flaky tests are worse than no tests — invest heavily in test stability and determinism.
  • ROI of automation is only realised after multiple regression cycles — account for maintenance cost.
⚡ Expert Pro Tip

Never automate a test you haven't manually validated first. Automating a poorly understood scenario just makes the wrong thing run faster.
