Test Phase Documentation
What Happens in This Phase
The Test phase validates that software meets requirements and performs correctly under expected conditions. Documentation includes test plans, coverage reports, security test results, and performance baselines. AI generates test documentation from test code and execution results, with humans validating accuracy and completeness.
Note: For comprehensive guidance on AI-assisted testing practices, see the AI4SDLC Testing Play.
Where AI Helps
- Generating test coverage reports from test execution results
- Documenting test plans based on requirements and acceptance criteria
- Creating security test result summaries from SAST/DAST tool outputs
- Producing performance baseline documentation from load test results
- Identifying coverage gaps by analyzing requirements vs. test mappings
Example: Test Coverage Summary
This example demonstrates GenAI Generation—AI synthesizes structured test execution data into human-readable coverage documentation that requires validation but minimal rework.
Context Setup
Before prompting, the tester provided:
- pytest execution results (test_auth_results.xml)
- Requirements documents (REQ-AUTH-*.md files)
- Test type classifications (unit, integration, security)
- Coverage tool output with line and branch metrics
Prompt
"Generate a test coverage summary for the authentication module. Include: requirements covered, test types (unit, integration, security), pass/fail rates, and identified gaps. Base this on the pytest results in test_auth_results.xml and the requirements in REQ-AUTH-.md files."*
Output
# Authentication Module Test Coverage Summary
## Requirements Coverage
| Requirement | Unit | Integration | Security | Status |
|-------------|------|-------------|----------|--------|
| REQ-AUTH-001: Login | ✓ | ✓ | ✓ | Covered |
| REQ-AUTH-002: MFA | ✓ | ✓ | ✓ | Covered |
| REQ-AUTH-003: Session timeout | ✓ | - | - | Partial |
| REQ-AUTH-004: Password policy | ✓ | ✓ | ✓ | Covered |
## Execution Summary
- Total tests: 47
- Passed: 45 (96%)
- Failed: 2 (4%)
- Coverage: 87% line, 72% branch
## Identified Gaps
- REQ-AUTH-003: Missing integration test for session timeout across services
- No negative testing for brute-force prevention (REQ-AUTH-005)
What AI-Generated Test Documentation Often Misses
- Test quality vs. quantity - High coverage doesn't mean meaningful tests
- Environmental dependencies - Tests that pass locally but fail in CI/CD
- Flaky test patterns - Intermittent failures not reflected in summary
- Security test context - Whether findings are exploitable in deployment
- Requirements not yet testable - Deferred or blocked test scenarios
Human reviewers must validate that coverage reflects actual requirement validation.
Governance Checklist
Before accepting AI-assisted Test phase documentation:
- [ ] Test coverage traces to specific requirements
- [ ] Failed tests explained with remediation status
- [ ] Security test results reviewed by security team
- [ ] Performance baselines compared against SLAs
- [ ] Coverage gaps documented with mitigation plans
Brownfield Additions
For modernization efforts, Test phase requires additional focus:
- Legacy test coverage gap analysis - Compare existing test coverage against modernization requirements
- Regression test documentation - Ensure legacy behavior preserved where required
- Validation against original requirements - Verify modernized system meets original mission intent
