♿

Accessibility Testing

Make sure the product works for people using a keyboard, a screen reader or a magnifier — and prove it, which is increasingly a legal requirement rather than a kindness.

  • WCAG 2.2: A and AA criteria, and the ones that actually fail
  • Automated Scans: axe-core, Pa11y and Lighthouse in the pipeline
  • Keyboard Paths: Focus order, focus traps and skip links
  • Screen Readers: NVDA, VoiceOver, and what they announce
  • Colour & Contrast: Ratios, state, and signals that do not rely on colour
  • Where Tools Stop: The roughly two thirds no scanner can see
⚙️

CI/CD & Test Infrastructure

Where the suite runs, how long it takes and whether anyone still trusts it — the part of automation that decides if the rest gets used.

  • Pipeline Stages: What runs on commit, on merge, and nightly
  • Parallel Execution: Sharding, workers and wall-clock time
  • Flaky Tests: Quarantine, retry policy and root-cause triage
  • Containers: Reproducible browsers, services and seed data
  • Failure Artefacts: Traces, videos and screenshots worth reading
  • Environments: Ephemeral stacks and the cost of keeping them

🎯 QA Best Practices & Methodologies

AI-Augmented Test Design

Use LLMs to generate test cases, edge cases, and boundary conditions from requirements or existing code — dramatically cutting authoring time.

Agentic Test Orchestration

Deploy autonomous AI agents that can plan, execute, and triage test runs end-to-end without human intervention, surfacing only what needs review.

Self-Healing Automation

Adopt frameworks that detect broken locators or changed layouts and automatically update tests, reducing maintenance burden by over 60%.

Shift-Left with AI Assistance

Combine shift-left principles with AI code review and inline test suggestions to catch defects at the earliest possible stage in the dev cycle.

Continuous Intelligence in CI/CD

Embed AI-powered flakiness detection, failure classification, and risk scoring into CI pipelines for smarter, faster quality gates.

Human-in-the-Loop Review

Keep engineers in control by routing AI-generated tests and agent findings through a review step before they gate deployments or close tickets.
