[feature]: Add Playwright E2E Testing Infrastructure

[YadavAkhileshh]

Overview

RUXAILAB currently has no automated E2E tests, so regressions in critical flows can go undetected. This issue proposes adding Playwright as the testing framework to fix that.

Problem

• No automated test coverage exists
• PRs rely entirely on manual review
• New contributors have no test baseline to work from

What I Plan to Add

• playwright.config.js — base configuration
• tests/auth.spec.js — auth flow tests
• .github/workflows/playwright.yml — runs tests on every PR

Test Coverage (Phase 1)

• Login page loads correctly
• Login form has email and password fields
• Error shown on invalid credentials

Roadmap

• tests/test-creation.spec.js — usability test creation flow
• tests/heuristic-evaluation.spec.js — heuristic evaluation forms
• tests/dashboard.spec.js — analytics and results views
• Accessibility testing with @axe-core/playwright

Note

I'm a GSoC 2026 contributor for the Playwright Testing project. Already on Discord and set up locally happy to adjust scope based on feedback before submitting the PR.
