Context

Part of Epic #402 — Pre-flight. This is TEST-2: rewrite every test that TEST-1 (#403) flagged as NOT DETECTED (tautological — passes regardless of whether the code under test works).

Per the Legibility Rubric, this addresses C8.1 (Critical).

Inputs

The NOT DETECTED register from docs/audits/test-mutation-report.md (produced by TEST-1, #403)

Method

For each tautological test:

Read the test and the service method it claims to test
Identify what the test is REALLY asserting (often: that the mock was called)
Replace the assertion with one that would FAIL if the service implementation were broken
Re-run the original mutation from TEST-1 and confirm the test now FAILS

Common patterns to fix:

Mock-only assertion — verify(repo).save(any()) with no assertion on what was saved → assert on the saved object's fields
Echo assertion — service returns dto and test asserts result == dto → assert on the dto's fields, including any field the service is supposed to populate
Empty happy path — test sets up minimal data and asserts no exception thrown → add assertions on returned object state
Stubbed dependencies hide behavior — service calls multiple collaborators but test only verifies one → assert on the orchestration outcome end-to-end

Acceptance criteria

Every test flagged as NOT DETECTED in TEST-1's (#403) report has been rewritten
Each rewritten test has been re-mutation-tested and now correctly FAILS on its mutation
docs/audits/test-mutation-report.md is updated with the new DETECTED results
Per-domain pass-rate after this issue closes is ≥90% on the sampled tests
Full backend test suite passes (./mvnw test green)
PR opened (adding rewritten tests + updated report) and merged before this issue is closed

Dependency

Hard dependency on TEST-1 (#403) completion (need its NOT DETECTED register to know what to fix).

Definition of Done

PR merged; closing comment lists how many tests were rewritten per domain and the final pass-rate.

Dispatch

Best done by an agent with full file-edit access. Memory: red-green TDD applies — run the failing mutation BEFORE rewriting the test, then rewrite, then verify.

👩‍💻 Felix Brandt — Senior Fullstack Developer

Observations

The four tautological patterns listed in the issue body are accurate and match what I found in the codebase. The most common offenders in the existing test suite are:
- verify(annotationRepository).save(any()) with no assertion on what was saved (e.g. AnnotationServiceTest.createAnnotation_savesAnnotation() — the result is asserted equal to the mocked return value, not to fields the service is supposed to populate)
- verify(blockRepository).save(any()) in TranscriptionServiceGuidedTest — two tests (upsertGuidedBlock_createsNewBlock_whenAnnotationHasNoBlock and upsertGuidedBlock_updatesExistingOcrBlock_whenAnnotationHasOcrBlock) add a bare verify alongside meaningful field assertions; the verify line is redundant noise but the field assertions are real
- verify(tokenRepository).save(any()) in PasswordResetServiceTest lines 161 and 176 — only interaction-verified, no saved object state asserted
The echo assertion pattern shows up in TagServiceTest.findOrCreate_createsNew_whenNameNotFound() — the service returns saved (the mocked return) and the test asserts result.isEqualTo(saved). If the service were changed to return null, or to return a differently-constructed object, this test still passes. The field-level assertion (result.getName().isEqualTo("Krieg")) is what needs to be there instead.
TranscriptionServiceGuidedTest actually has mostly good assertions — result.getText(), result.getSource(), result.getAnnotationId() are all field-level. These will survive mutations correctly. The bare verify(blockRepository).save(any()) at the end of those tests is noise, not tautology.
The hard dependency on #403 not being complete yet is the real gating issue. The NOT DETECTED register doesn't exist — there is no docs/audits/test-mutation-report.md. The issue's "Method" section says to read that file first. Without it, an agent picking up this ticket would either need to re-run the mutation pass itself or wait for #403 to land.

Recommendations

Before touching a single test: either confirm #403 is complete and the report exists, or fold the mutation-pass step into the scope of this issue explicitly. Right now the issue inherits a hard-blocked input.
For every tautological test rewritten, use thenAnswer(inv -> inv.getArgument(0)) on the save() stub so the service's mutations are visible in the result object, then assert individual fields — not the object identity.
Specifically for echo assertions like assertThat(result).isEqualTo(saved) — replace with at minimum two field assertions: one on the identity field the service is supposed to set, one on a business field. That way a missing setter causes a failure.
Red-green check: before each rewrite, run the mutation that exposed the tautology and confirm the current test passes. Then rewrite the assertion so it fails. Then revert the mutation and confirm it goes green. Three commands, every time.
The mutation report update (acceptance criterion 3) is the artifact that closes the loop — don't skip it.

🏗️ Markus Keller — Senior Application Architect

Observations

This is pure test hygiene work within the existing service layer. No architectural changes are implied, which is appropriate — fixing a tautological test does not require touching production code.
The scope is intentionally narrow: rewrite flawed assertions, re-run a targeted mutation, update a report. The method is well-defined. I have no structural objections.
One architectural signal worth noting: the mock-only assertion pattern (verify(repo).save(any())) is a symptom of testing the interaction contract rather than the behavioral contract. This is a valid distinction architecturally — some tests should verify that a downstream collaborator was called (interaction testing), while others should verify what state resulted (state testing). The issue correctly identifies the tests that need to shift from interaction to state testing. The fix is test-side only.
The four tautological patterns listed are all service-layer unit tests using @ExtendWith(MockitoExtension.class) with @InjectMocks. That's the correct setup — no architectural change needed there.
The acceptance criterion "per-domain pass-rate ≥ 90%" is a reasonable target for service unit tests. It implicitly acknowledges that some interaction-only assertions (like "save was never called on the not-found path") are legitimately correct and should remain.

Recommendations

Keep the scope discipline: this issue fixes assertions only. If a test requires structural changes to the service to become testable (e.g., a static call that can't be observed), that is a separate refactoring issue. Don't mix refactoring and test-fixing in the same PR.
The docs/audits/test-mutation-report.md artifact is a valuable architectural decision log. Store it permanently in the repo, not as a temp file. This is the kind of evidence that prevents future developers from regressing the same tests.
The PR description should list the exact tests rewritten and their before/after assertion shape. Future reviewers need to be able to verify the fix was meaningful without re-running the mutations themselves.

🛡️ Nora "NullX" Steiner — Application Security Engineer

Observations

This issue's scope is test quality, not security functionality. I scanned the tautological patterns described for security implications and found one worth flagging:
- The permission boundary tests in GeschichteControllerTest and similar controller tests use @WithMockUser + status().isUnauthorized() patterns — those are real assertion-based tests, not mock-only. They would catch mutations. No concern there.
- The service tests being fixed here (document, person, tag, user) don't directly test security logic, so a tautological test that fails to detect a mutation in DocumentService.updateDocument() or TagService.update() could mask a subtle authorization gap. Specifically, if the service is supposed to enforce a field-level permission check before persisting, a verify(repo).save(any()) test never proves that check ran.
I found no verify(repo).save(any()) calls in the security-adjacent code paths — UserService tests use ArgumentCaptor and argThat patterns properly. That's good.
The AnnotationServiceTest.createAnnotation_savesAnnotation() test asserts result.isEqualTo(saved) where saved is the mocked return. If the service is modified to drop the createdBy field (setting it to null instead of the authenticated user), this test does not catch it. That field is a security-relevant audit trail — who created the annotation matters. This specific case is a security concern masked by the tautology.

Recommendations

When rewriting AnnotationServiceTest.createAnnotation_savesAnnotation(), add an explicit assertion: assertThat(result.getCreatedBy()).isEqualTo(userId). This guards the security-relevant audit field.
For any create* or update* service test that deals with user-owned entities, always include an assertion on the ownership/audit field (createdBy, authorId, modifiedBy). These fields are where authorization bypass would silently manifest.
The PasswordResetServiceTest lines 161/176 that only verify(tokenRepository).save(any()) should be updated to also assert that the saved token's user reference and expiry are correct. A mutation that sets the wrong user ID on a reset token would pass the current test — and that's a direct account takeover vector.

Open Decisions (none — all findings have concrete fixes)

🧪 Sara Holt — Senior QA Engineer

Observations

The issue is precisely scoped and the method is sound. The red-green verification step (run mutation → confirm test passes → rewrite → confirm test fails → revert → confirm test passes again) is the correct process. The issue explicitly notes this, which is reassuring.
The hard dependency on #403 is the biggest risk to this issue's execution. The docs/audits/test-mutation-report.md does not exist yet. If an agent picks up this issue before #403 lands, it will either produce a report with a different set of findings than #403 intended (de-synced audit trail) or be forced to re-do the mutation pass. The issue says "hard dependency" but doesn't block the issue state. Consider adding a Gitea blocked-by reference to make this machine-readable.
From my review of the codebase, the most concentrated tautological risk is in:
1. AnnotationServiceTest — multiple verify(annotationRepository).save(any()) calls with no ArgumentCaptor field inspection
2. TranscriptionServiceGuidedTest — good field assertions but redundant bare verify lines that will survive any mutation silently
3. PasswordResetServiceTest — verify(tokenRepository).save(any()) with no assertion on the saved object's token value, user reference, or expiry
The acceptance criterion "every test flagged as NOT DETECTED has been rewritten" depends entirely on #403's completeness and accuracy. If #403 sampled tests poorly, this issue would close with untouched tautologies in domains not covered by that sample.
The ≥90% pass-rate target is measurable and reasonable. Document the baseline from #403 and the after state explicitly in the closing comment — this creates an auditable before/after.

Recommendations

Use ArgumentCaptor for every verify(repo).save(any()) conversion. Capture the saved entity and assert on its fields rather than just verifying the call happened. This is the mechanical fix for the mock-only assertion pattern:

ArgumentCaptor<InviteToken> captor = ArgumentCaptor.forClass(InviteToken.class);
verify(tokenRepository).save(captor.capture());
assertThat(captor.getValue().getUserId()).isEqualTo(expectedUserId);
assertThat(captor.getValue().getExpiresAt()).isAfter(LocalDateTime.now());

For echo assertions (assertThat(result).isEqualTo(savedMock)), replace with field-by-field assertions on at least the service-computed fields — fields the service sets, not fields passed directly from the DTO unchanged.
After all rewrites, run the full backend test suite (./mvnw test) once before opening the PR to catch any collateral failures from the assertion changes.

🚀 Tobias Wendt — DevOps & Platform Engineer

Observations

This is a pure backend Java test improvement — no infrastructure, Docker, CI configuration, or deployment changes are implied or needed. I have nothing structural to flag.
One CI-adjacent note: the acceptance criterion requires ./mvnw test to be green. The Gitea Actions CI pipeline already runs this. The PR will validate green automatically — no CI change needed for this issue.
The mutation testing approach described (Approach A — manual targeted mutation) does not require any tooling additions (no PIT plugin permanently in pom.xml). That's the right call for a cleanup issue — no infrastructure churn.
If Approach B (PIT) were used in the future as a recurring quality gate, I'd recommend a separate dev-profile-only addition to pom.xml with the PIT plugin pinned to a specific version, gated behind a -Ppitmutation Maven profile so it never runs in normal CI. That's a future consideration, not a blocker for this issue.

No concerns from my angle.

The issue is backend test code only. CI will validate the suite green automatically on the PR. No infrastructure, no secrets, no deployment artifacts involved.

📋 Elicit (Requirements) — Senior Requirements Engineer

Observations

The issue is unusually well-specified for a test quality task. It has a clear method, defined inputs, four concrete anti-pattern categories to fix, measurable acceptance criteria (≥90% pass-rate, every NOT DETECTED test rewritten), and a documented Definition of Done.
One requirement gap: the acceptance criterion "every test flagged as NOT DETECTED in TEST-1's report has been rewritten" creates an implicit completeness bound. If TEST-1 sampled only 5 tests per domain and missed a tautological test in the sample, this issue closes with a false sense of completeness. The requirement is bounded by the sample quality of #403, but that bound is not stated.
The "≥90% on the sampled tests" target is testable. The acceptance criterion is measurable. That is good requirements hygiene.
The hard dependency on #403 is stated but the issue doesn't specify what "completion" means for #403 — specifically, does #403's PR need to be merged (not just opened) before this issue can start? The issue says "Hard dependency on TEST-1 (#403) completion" but the DoD for #403 says "PR merged." I'd read this as: #403's PR must be merged before #404 can begin, which means the docs/audits/test-mutation-report.md must be in the main branch.
The "closing comment lists how many tests were rewritten per domain and the final pass-rate" DoD requirement is a good traceability anchor. It should reference the before-state pass-rates from #403's report so the delta is visible.

Recommendations

Add an explicit precondition to the issue: "Precondition: docs/audits/test-mutation-report.md exists in the repository (merged via #403)." This prevents premature execution.
Consider adding "per-domain baseline from #403" as a required input row in the closing comment format — so the DoD explicitly captures before/after rather than just after.
The scope boundary is clear: this issue modifies test files only, not production service code. That boundary should be stated explicitly to prevent an agent from "fixing" a tautology by simplifying the service under test instead of strengthening the assertion.

🎨 Leonie Voss — UX Designer & Accessibility Strategist

No concerns from my angle.

This issue is entirely backend Java test code with no frontend, UI, or accessibility surface area. I checked: the four anti-patterns described (mock-only assertions, echo assertions, empty happy paths, stubbed dependencies) are back-end unit testing concerns. No Svelte components, no accessibility implications, no visual regressions.

The only note I'd raise from a product perspective: if the legibility epic (#402) ultimately produces a significantly refactored backend, the E2E tests (Playwright) may need updates once the service behavior is better-specified by these strengthened unit tests. That is a future concern for a different issue.
