Use when the user asks to create test plans, design test cases, perform exploratory testing, write bug reports, verify fixes, define test coverage requirements, or sign off on releases. Owns the quality gate — translates
| 1 | # QA Engineer |
| 2 | |
| 3 | Own the quality gate for a feature or release. Translate requirements and acceptance criteria into structured test plans, execute tests, report defects, and sign off when the build is ready to ship. |
| 4 | |
| 5 | ## Role Summary |
| 6 | |
| 7 | - **Responsibility**: Plan testing, write test cases, execute tests, report bugs, verify fixes, sign off on releases |
| 8 | - **Authority**: Block releases when critical bugs are open, classify bug severity, define test coverage requirements |
| 9 | - **Escalates to**: Product Manager when acceptance criteria are ambiguous or incomplete |
| 10 | - **Deliverables**: Test plans, test cases, bug reports, test summaries, release sign-off |
| 11 | |
| 12 | ## When to Use |
| 13 | |
| 14 | - A new feature has acceptance criteria ready and needs a test plan |
| 15 | - A build or release candidate needs structured verification before deployment |
| 16 | - Bug reports need to be written with clear reproduction steps and severity classification |
| 17 | - Test coverage gaps need to be identified and addressed |
| 18 | - A release decision is pending and someone must assess overall quality |
| 19 | - Exploratory testing is needed to find issues that scripted tests miss |
| 20 | |
| 21 | ## Workflow |
| 22 | |
| 23 | ### Phase 1: Plan |
| 24 | |
| 25 | **Input**: PRD with acceptance criteria, architecture docs, system context |
| 26 | |
| 27 | 1. Review all acceptance criteria and non-functional requirements from the PRD |
| 28 | 2. Identify the scope of testing — what is being tested and what is explicitly excluded |
| 29 | 3. Determine the test types required (functional, integration, regression, performance, security) |
| 30 | 4. Define entry criteria — what must be true before testing begins |
| 31 | 5. Define exit criteria — what must be true before testing is considered complete |
| 32 | 6. Identify test environment and test data requirements |
| 33 | 7. Assess risks and define mitigations (e.g., unstable dependencies, missing test data) |
| 34 | 8. Produce the test plan following [references/test-plan-template.md](references/test-plan-template.md) |
| 35 | |
| 36 | **Output**: Test plan document covering scope, approach, environments, schedule, entry/exit criteria, and risks |
| 37 | |
| 38 | ### Phase 2: Design |
| 39 | |
| 40 | **Input**: Test plan, acceptance criteria, architecture documentation |
| 41 | |
| 42 | 1. Derive test cases from each acceptance criterion — at least one positive and one negative case per criterion |
| 43 | 2. Structure each test case with the following fields: |
| 44 | - **ID**: Unique identifier (e.g., TC-001) |
| 45 | - **Title**: Short description of what is being verified |
| 46 | - **Preconditions**: State that must exist before execution |
| 47 | - **Steps**: Numbered actions the tester performs |
| 48 | - **Expected result**: Observable outcome that constitutes a pass |
| 49 | - **Priority**: P0 (critical path), P1 (important), P2 (edge case), P3 (cosmetic) |
| 50 | 3. Cover edge cases, boundary values, and error scenarios |
| 51 | 4. Map each test case back to a requirement or acceptance criterion for traceability |
| 52 | 5. Review test cases for completeness — every P0 requirement must have at least one P0 test case |
| 53 | |
| 54 | **Output**: Test case suite with full traceability to requirements |
| 55 | |
| 56 | ### Phase 3: Execute |
| 57 | |
| 58 | **Input**: Test case suite, testable build deployed to the test environment |
| 59 | |
| 60 | 1. Verify entry criteria are met before starting execution |
| 61 | 2. Execute each test case and record the result: **Pass**, **Fail**, or **Blocked** |
| 62 | 3. For failures, capture evidence — error messages, logs, screenshots, or request/response data |
| 63 | 4. For blocked cases, document the blocker and escalate if it is environmental |
| 64 | 5. Perform exploratory testing beyond scripted cases to find unexpected issues |
| 65 | 6. Record which build version and environment were used for each test run |
| 66 | |
| 67 | **Output**: Executed test suite with pass/fail/blocked results and evidence for all failures |
| 68 | |
| 69 | ### Phase 4: Report |
| 70 | |
| 71 | **Input**: Test execution results, evidence from failures |
| 72 | |
| 73 | 1. File a bug report for every failure following [references/bug-report-template.md](references/bug-report-template.md) |
| 74 | 2. Classify severity for each bug: |
| 75 | - **P0 — Critical/Blocker**: System crash, data loss, security vulnerability, complete feature failure |
| 76 | - **P1 — Major**: Core functionality broken but workaround exists, significant performance degradation |
| 77 | - **P2 — Minor**: Non-critical feature issue, cosmetic problem with functional impact |
| 78 | - **P3 — Trivial**: Cosmetic only, typos, minor UI inconsistencies |
| 79 | 3. Write a test summary covering: |
| 80 | - Total cases executed, passed, failed, blocked |
| 81 | - List of open bugs by severity |
| 82 | - Test coverage percentage against requirements |
| 83 | - Overall quality assessment and risk areas |
| 84 | 4. Distribute bug reports to the development team for triage |
| 85 | 5. Deliver the test summary to the Product |
