Document the Issue +In the regression test file, add a new `describe` block with: +```typescript +describe("Regression: Issue #XXX - [Issue Title]", () => { + // Bug description + // Fix description + // Related files/PRs +}); +``` + +### 2. Write Regression Tests +Add tests that verify the fix remains in place: +```typescript +it("should prevent [specific bug from reoccurring]", () => { + // Test implementation +}); + +it("should maintain [specific fix behavior]", () => { + // Test implementation +}); +``` + +### 3. Consider Dedicated Test Files +For complex fixes, create a dedicated test file instead of adding to the main regression suite: +- If the fix involves multiple components or complex logic +- If the test suite would be large (>50 lines) +- If the fix is security-critical or high-risk + +### 4. Update CI Configuration +If the regression test is in a separate file, ensure it's covered by the existing test command. The main regression suite is explicitly run in CI via: +```yaml +- name: Run regression tests + run: pnpm test -- src/test/regression.test.ts +``` + +### 5. Update Documentation +- Add the issue to the "Currently Tracked Issues" section in this file +- Reference any related documentation files +- Note the test locations + +## Running Regression Tests + +### Run all regression tests: +```bash +cd frontend +pnpm test -- src/test/regression.test.ts +``` + +### Run specific regression suite: +```bash +cd frontend +pnpm test -- src/test/regression.test.ts -t "Issue #82" +``` + +### Run all tests (includes regression): +```bash +cd frontend +pnpm test +``` + +## CI Integration + +Regression tests are automatically run in CI via `.github/workflows/frontend-ci.yml`: +1. **Unit and E2E tests**: Runs all tests including regression tests +2. **Regression tests**: Explicitly runs the main regression suite for visibility + +Both steps must pass for a PR to merge (assuming branch protection is configured). + +## Best Practices + +### DO: +- Add regression tests for every bug fix +- Reference the specific issue number in test descriptions +- Document what the bug was and how it was fixed +- Keep regression tests focused on preventing the specific bug +- Update this documentation when adding new regression tests + +### DON'T: +- Add regression tests for features that haven't had bugs +- Remove regression tests without a compelling reason +- Make regression tests overly complex +- Forget to update CI if adding new regression test files + +## Maintenance + +### When to Remove Regression Tests +Regression tests should generally remain indefinitely.
