+## Step 5: Test Specifications
+
+**Role**: Professional Quality Assurance Engineer
+
+**Goal**: Write test specs for each component achieving minimum 75% acceptance criteria coverage
+
+**Constraints**: Test specs only — no test code. Each test must trace to an acceptance criterion.
+
+1. For each component, write tests using `templates/test-spec.md` as structure
+2. Cover all 4 types: integration, performance, security, acceptance
+3. Include test data management (setup, teardown, isolation)
+4. Verify traceability: every acceptance criterion from `acceptance_criteria.md` must be covered by at least one test
+
+**Self-verification**:
+- [ ] Every acceptance criterion has at least one test covering it
+- [ ] Test inputs are realistic and well-defined
+- [ ] Expected results are specific and measurable
+- [ ] No component is left without tests
+
+**Save action**: Write each `components/[##]_[name]/tests.md`
