Mock @prisma/client globally in bun-setup.ts to allow unit tests to run
without requiring the generated Prisma client. This improves test isolation
and allows tests to pass even when prisma generate hasn't been run.
Add afterEach hook to clear document.body.innerHTML between tests.
This prevents test pollution where elements from previous tests
interfere with subsequent test queries.
- Update all test files to use named mock variables instead of inline mocks
- Clear mock history in beforeEach instead of using mock.restore()
- Add default mock implementations stored at module level
- Document that tests should not use --randomize flag due to mock.module() limitations
- All 89 unit tests pass consistently without randomization
- Install Bun via mise
- Update package.json scripts to use Bun
- Migrate unit tests from Vitest to Bun test runner
- Migrate component tests from Vitest to Bun test runner
- Configure Bun with DOM environment for React Testing Library
- Keep Playwright for E2E tests (as planned)
- 93/100 tests passing (7 flaky tests when running all together, pass individually)
