Does the input change by reference or just mutation? + - Is `markForCheck()` or `detectChanges()` missing after an async operation? + - Is the component using signals? Check that computed signals depend on the right reactive sources. + + **Dependency Injection:** + - Trace the provider tree. Is the service provided at the right level (`root`, component, module)? + - Is there an unexpected singleton vs. per-component instance? + - Is a `providedIn: 'root'` service being accidentally overridden by a module provider? + + **Lifecycle Hooks:** + - `ngOnInit` fires after first `detectChanges()`. Don't access DOM here. + - `ngAfterViewInit` fires after child views initialize. `@ViewChild` is `undefined` before this. + - `ngOnChanges` fires before `ngOnInit` and on every input change. + + **Zone.js:** + - Is the code running outside NgZone (e.g., third-party callback, `requestAnimationFrame`, WebSocket)? + - Does wrapping in `NgZone.run()` fix it? + + **Harness Environment:** + - For overlay-based components (modals, flyouts, popovers), use `TestbedHarnessEnvironment.documentRootLoader(fixture)` not `.loader(fixture)`. + - Harness methods are async — are you awaiting them? + + See `references/angular-debugging.md` in this directory for detailed guidance. + +### Phase 2: Pattern Analysis + +**Find the pattern before fixing:** + +1. **Find Working Examples** + - Locate similar working code in same codebase + - In this monorepo, search `libs/components/` for a working component similar to yours + - Harness tests in `*/testing/src/` demonstrate the canonical interaction pattern + +2. **Compare Against References** + - If implementing pattern, read reference implementation COMPLETELY + - Read the corresponding harness class to understand what DOM structure the component exposes for testing + - Don't skim — read every line + - Understand the pattern fully before applying + +3. **Identify Differences** + - What's different between working and broken? + - List every difference, however small + - Pay attention to: standalone vs. non-standalone components, module imports vs. standalone imports, `data-sky-id` attribute presence + - Don't assume "that can't matter" + +4. **Understand Dependencies** + - What other components does this need? + - Check if the component requires a service, an overlay container, or specific module imports + - What settings, config, environment? + - What assumptions does it make? + +### Phase 3: Hypothesis and Testing + +**Scientific method:** + +1. **Form Single Hypothesis** + - State clearly: "I think X is the root cause because Y" + - Write it down + - Be specific, not vague + +2. **Test Minimally** + - Make the SMALLEST possible change to test hypothesis + - One variable at a time + - Don't fix multiple things at once + +3. **Angular Isolation Techniques** + - Use `TestBed.configureTestingModule()` to create a minimal reproduction with only the modules/components needed + - For change detection hypotheses: toggle between `ChangeDetectionStrategy.Default` and `OnPush` in the test component + - For DI hypotheses: provide a spy service to verify calls + - For timing hypotheses: use `fakeAsync`/`tick` to control time precisely + - For harness hypotheses: verify harness finds the element with `loader.getHarness()` before testing behavior + +4. **Verify Before Continuing** + - Did it work? Yes → Phase 4 + - Didn't work? Form NEW hypothesis + - DON'T add more fixes on top + +5. **When You Don't Know** + - Say "I don't understand X" + - Don't pretend to know + - Ask for help + - Research more + +### Phase 4: Implementation + +**Fix the root cause, not the symptom:** + +1. **Create Failing Test Case** + - Use component harnesses for the regression test: + 1. Set up `TestBed` with the component under test + 2. Create harness loader: `TestbedHarnessEnvironment.loader(fixture)` (or `documentRootLoader` for overlays) + 3. Get the harness: `const harness = await loader.getHarness(SkyXxxHarness)` + 4. Write the assertion that fails: `await expectAsync(harness.getSomething()).toBeResolvedTo(expected)` + 5. Watch the test fail + - Use the `skyux-test-driven-development` skill for writing proper failing tests + +2. **Implement Single Fix** + - Address the root cause identified + - ONE change at a time + - No "while I'm here" improvements + - No bundled refactoring + +3. **Verify Fix** + - Test passes now? + - No other tests broken? + - Issue actually resolved? + +4. **If Fix Doesn't Work** + - STOP + - Count: How many fixes have you tried? + - If < 3: Return to Phase 1, re-analyze with new information + - **If ≥ 3: STOP and question the architecture (step 5 below)** + - DON'T attempt Fix #4 without architectural discussion + +5. **If 3+ Fixes Failed: Question Architecture** + + **Pattern indicating architectural problem:** + - Each fix reveals new shared state/coupling/problem in different place + - Fixes require "massive refactoring" to implement + - Each fix creates new symptoms elsewhere + + **STOP and question fundamentals:** + - Is this pattern fundamentally sound? + - Are we "sticking with it through sheer inertia"? + - Should we refactor architecture vs. continue fixing symptoms? + + **Discuss with your human partner before attempting more fixes** + + This is NOT a failed hypothesis — this is a wrong architecture. + +## Red Flags - STOP and Follow Process + +If you catch yourself thinking: + +- "Quick fix for now, investigate later" +- "Just try changing X and see if it works" +- "Add multiple changes, run tests" +- "Skip the test, I'll manually verify" +- "It's probably X, let me fix that" +- "I don't fully understand but this might work" +- "Pattern says X but I'll adapt it differently" +- "Here are the main problems: [lists fixes without investigation]" +- Proposing solutions before tracing data flow +- **"One more fix attempt" (when already tried 2+)** +- **Each fix reveals new problem in different place** + +**ALL of these mean: STOP.

Return to Phase 1. + +## Common Rationalizations + +| Excuse | Reality | +| -------------------------------------------------------- | ----------------------------------------------------------------------------- | +| "Issue is simple, don't need process" | Simple issues have root causes too. Process is fast for simple bugs. | +| "Emergency, no time for process" | Systematic debugging is FASTER than guess-and-check thrashing. | +| "Just try this first, then investigate" | First fix sets the pattern. Do it right from the start. | +| "I'll write test after confirming fix works" | Untested fixes don't stick. Test first proves it. | +| "Multiple fixes at once saves time" | Can't isolate what worked. Causes new bugs. | +| "Reference too long, I'll adapt the pattern" | Partial understanding guarantees bugs. Read it completely. | +| "I see the problem, let me fix it" | Seeing symptoms ≠ understanding root cause. | +| "One more fix attempt" (after 2+ failures) | 3+ failures = architectural problem. Question pattern, don't fix again. | +| "ng-mocks makes setup easier" | It replaces Angular's real behavior with stubs. You end up testing a fiction. | +| "I'll query the DOM directly, harness is too much setup" | Harnesses are the contract. Direct DOM queries break on internal refactors. | + +## Quick Reference + +| Phase | Key Activities | Success Criteria | +| --------------------- | -------------------------------------------------------------------------------------- | --------------------------- | +| **1.

Test takes 30 seconds. | +| "I'll test after" | Tests passing immediately prove nothing. | +| "Tests after achieve same goals" | Tests-after = "what does this do?" Tests-first = "what should this do?" | +| "Already manually tested" | Ad-hoc ≠ systematic. No record, can't re-run. | +| "Deleting X hours is wasteful" | Sunk cost fallacy. Keeping unverified code is technical debt. | +| "Keep as reference, write tests first" | You'll adapt it. That's testing after. Delete means delete. | +| "Need to explore first" | Fine. Throw away exploration, start with TDD. | +| "Test hard = design unclear" | Listen to test. Hard to test = hard to use. | +| "TDD will slow me down" | TDD faster than debugging. Pragmatic = test-first. | +| "Manual test faster" | Manual doesn't prove edge cases. You'll re-test every change. | +| "Existing code has no tests" | You're improving it. Add tests for existing code. | +| "I'll just query the DOM directly" | Harnesses are the stable API. Internal CSS classes change without notice. | +| "ng-mocks makes setup easier" | It replaces Angular's real behavior with stubs. You end up testing a fiction. Use real components + jasmine spies. | + +## Red Flags - STOP and Start Over + +- Code before test +- Test after implementation +- Test passes immediately +- Can't explain why test failed +- Tests added "later" +- Rationalizing "just this once" +- "I already manually tested it" +- "Tests after achieve the same purpose" +- "It's about spirit not ritual" +- "Keep as reference" or "adapt existing code" +- "Already spent X hours, deleting is wasteful" +- "TDD is dogmatic, I'm being pragmatic" +- "This is different because..." +- Querying internal DOM classes when a harness exists +- Importing `ng-mocks` or `MockBuilder` +- Using deprecated `Sky*Fixture` classes instead of `Sky*Harness` +- Using deprecated `Sky*TestingModule` instead of `provide*Testing()` functions + +**All of these mean: Delete code.
