How do we generate DTAC Domain 3 test evidence with Playwright?

NHS DTAC Domain 3 test evidence from Playwright: (1) Playwright Trace Viewer (trace: on-first-retry) — captures full test execution video, network requests, console logs, and screenshots at each step. DTAC assessors can review exactly what the test tested. (2) axe-playwright accessibility scan — inject axe-core into every Playwright test page, automatically report WCAG 2.1 AA violations with specific element reference. (3) GitHub Actions artefact — upload Playwright HTML report (include traces and screenshots) as CI/CD artefact, retained 90 days — DTAC assessors can access. (4) Test naming convention — each E2E test named after the user story or DCB0129 mitigation it validates ('SR-045: dose calculator prevents overdose') — traceability to IEC 62304 requirements. ClickMasters generates DTAC Domain 3 test evidence pack from Playwright artefacts automatically.

Should UK projects test with Firefox and Safari as well as Chrome?

Yes — for UK regulated applications. WCAG 2.1 AA (NHS DTAC Domain 5, PSBAR): "must work for all users" includes users on Safari (iOS — 20% of UK mobile traffic) and Firefox (5% of UK desktop). Playwright multi-browser: test critical user journeys in Chromium, Firefox, and WebKit (Safari) in CI/CD. NHS NHS Design System: NHSUK Frontend tests in all 3 browsers — some CSS rendering differences in Safari require specific fixes. GOV.UK Design System: GDS tests in all major browsers — including iOS Safari (elderly population uses iPhones heavily — government digital services must work on iOS). ClickMasters CI/CD: Playwright runs Chromium in every PR (fast feedback), Firefox and WebKit in nightly scheduled runs (slower — catches browser-specific issues before they reach production).

Direct Answer

Playwright is ClickMasters' default for E2E testing in 2026: multi-browser (Chromium, Firefox, WebKit — Cypress is Chromium-only), faster execution (parallel tests across browsers), and NHS DTAC-compatible (Playwright Trace Viewer generates detailed test evidence). Cypress is right for component testing within React (Cypress Component Testing is genuinely excellent — better than Playwright for isolated React component tests). Selenium is legacy — new UK projects should use Playwright. E2E testing framework choice affects NHS DTAC Domain 3 test evidence quality, Cyber Essentials Annex A2 patch verification, and WCAG 2.1 AA automated accessibility testing.

Factor	Playwright	Cypress	Selenium WebDriver
Multi-browser (UK WCAG compliance)	✅ Chromium + Firefox + WebKit (Safari)	Chromium only — not Firefox/Safari	✅ All browsers — via WebDriver
NHS DTAC test evidence	✅ Playwright Trace Viewer — video + network + console	Cypress Dashboard — good evidence	Selenium Grid reports — verbose
WCAG automated testing in E2E	✅ axe-playwright (axe-core via Playwright)	✅ cypress-axe — good	axe-selenium — available
GOV.UK / NHS Design System testing	✅ Test at component level via Playwright fixtures	Cypress Component Test — good	Verbose setup required
CI/CD integration (GitHub Actions)	✅ Official Docker image + GitHub Action	✅ Official Docker image + GitHub Action	Docker image available — slower
Parallel test execution	✅ Native sharding — fast CI/CD	Cypress Parallelisation (paid plan)	Selenium Grid — complex setup
Component testing (React)	Playwright Component Test — available	✅ Best — Cypress Component Testing
ClickMasters default	✅ All E2E, API, and accessibility testing	React component unit/integration tests	Legacy projects only
