Gary Parker
Quality engineering for teams shipping with AI: I build open-source Playwright tooling and write up experiments with measured results.
writing
view all →- ARIA Snapshots: The Assertion Layer Your Locators Are MissingFour suites, three rounds of UI drift, five invisible accessibility regressions. The suite that survived best noticed least — and ARIA snapshots were the only assertions that caught everything.
- Self-Healing Tests: What the Vendors Aren't Telling YouI broke a test suite twice and let Playwright's healer agent fix it. It repaired everything, fast and correctly — and that's exactly the problem with the sales pitch.
- Your AI's Tests Pass. Here's What They Don't CheckAn agent wrote a module and its own tests: 100% line coverage, 90.67% mutation score. What the seven surviving mutants reveal about verifying AI-written code.
- Hands-On with Playwright Test Agents: Planner, Generator, Healer — MeasuredPlaywright's official test agents evaluated properly: generated suite quality vs a baseline, the 43-minute agentic tax, and why the healer should never run unsupervised.
- Ship One Test a DaySmall, consistent progress beats big-bang automation projects. The compound effect of daily test commits.
experiments
- poc-playwright-test-agentsMeasured evaluation of Playwright Test Agents (planner/generator/healer) against a one-pass baseline suite.
- poc-ai-code-test-coverageAn agent's own tests reached 100% line coverage and a 90.67% mutation score.
- poc-self-healing-selectorsOver two drift releases the healer made 14 repairs on a CSS-selector suite, 2 on ARIA, 1 on test IDs.
- poc-aria-snapshot-assertionsTest-ID assertions caught 0 of 5 seeded accessibility regressions; ARIA snapshots caught 5 of 5.
speaking
view all →- AI vs testers? Friend or foe?The conversation covered the integration of AI into testing workflows, the necessity for testers to adapt and acquire new skills, and the potential for AI to automate repetitive tasks, allowing human testers to focus on more complex, value-driven activities.
- Changing Role of Quality Engineering in the Age of AIDiscover the transformative impact of Artificial Intelligence on Quality Engineering (QE) in this panel discussion ‘Changing Role of Quality Engineering in the Age of AI’. The panel discussion brings together QE leaders who will explore the impact of AI in testing and software development roles.
- Creating Reliable and Scalable Test Automation FrameworksIn this XP Webinar, you'll explore best practices for building reliable and scalable test automation frameworks, ensuring faster development cycles, enhanced code quality, and improved test coverage across diverse platforms and applications.
