How it works

  1. 1

    Step 1: The exam

    20 questions drawn from 30, 30 minutes, pass mark 80%. Not the knowledge-check questions. Explanations after grading; retake after 24 hours, up to 3 attempts in 7 days.

  2. 2

    Step 2: Run a visual suite on TestingBot in two browsers

    4 passing browser tests in the build certificate-visual-regression-testing on 2 different browser configurations, in the last 30 days.

    How to run it

    Run a visual regression suite on the TestingBot grid in at least two browser configurations, for example Chrome on Windows 11 and Safari on macOS, and report every result to TestingBot.

    1. Use the grid setup from chapter 6: a testingbot.ts endpoint helper, a playwright.testingbot.config.ts with at least two projects on different browsers or operating systems, and a snapshotPathTemplate that stores one baseline per project.

    2. Write at least two visual tests with toHaveScreenshot() against a public page (the TodoMVC demo from the course works), with the stabilisation from chapter 2: element or viewport screenshots, and masks or a fixed clock for anything dynamic.

    3. Set the build name to certificate-visual-regression-testing in tb:options (in the course helper: TB_BUILD=certificate-visual-regression-testing).

    4. Report pass or fail for every session with the setSessionStatus fixture from chapter 6.

    5. Create and review the baselines (--update-snapshots=missing), then run the suite again so the comparisons pass:

      TB_BUILD=certificate-visual-regression-testing npx playwright test -c playwright.testingbot.config.ts

    The build needs at least four passed sessions across at least two browser configurations.
