Common Mistakes to Avoid

Misalignment between the chosen tool and the UI volatility or debugging needs causes repeated maintenance and slower failure recovery.

  • Choosing a code-only approach without a plan for UI-change maintenance

    Selenium automation can become flaky without disciplined waits and synchronization, and UI test maintenance requires ongoing locator and interaction refactoring. Tools like mabl and Testim are designed to reduce breakage using AI-assisted maintenance and self-healing locators.

  • Ignoring visual regression needs when pixel-level UI correctness matters

    DOM assertions alone can miss UI differences caused by layout changes, and large UI surfaces can create noise without disciplined baselining. Applitools Eyes is built for AI image comparison with baselining and review workflows that connect pixel diffs to triage.

  • Underestimating debugging workflow requirements for fast triage in CI

    When failures are frequent or asynchronous, teams lose time if they do not have replayable artifacts for investigation. Playwright’s Trace viewer and Cypress time-travel debugging both provide step-by-step replay evidence with DOM snapshots or command logs.

  • Using an automation framework without proper orchestration and dependencies for large suites

    Large Java automation suites can become brittle if dependency ordering and lifecycle structure are not enforced. TestNG provides dependency-based execution via dependsOnMethods and groups plus lifecycle hooks for structured setup and teardown.
