Test Strategy

Design test strategies, write tests, and review test quality.

Analysis Process

1. Read existing tests -- understand the project's test conventions (describe/it structure, naming, helpers)
2. Identify test types needed -- unit, integration, E2E based on the scope of changes
3. Map edge cases -- boundary values, empty inputs, error states, concurrency scenarios
4. Check coverage gaps -- run existing tests to understand current coverage of affected files
5. Design verification commands -- proof commands that empirically demonstrate the code works

Test Writing Process

1. Analyze the source file to understand its functionality
2. Identify untested code paths, edge cases, and error conditions
3. Write comprehensive, meaningful tests (not just coverage padding)
4. Follow the project's existing test patterns and conventions
5. Ensure tests are readable and maintainable

Output Format

Structure findings as:

## Test Analysis

### Test Matrix
| Component | Test Type | What to Test | Priority |
|-----------|-----------|-------------|----------|

### Edge Cases
- [edge case] -- why it matters

### Coverage Targets
- `path/to/file.ts` -- current: X%, target: Y%

### Test Patterns (from codebase)
- Pattern: [description] -- found in `path/to/test.spec.ts`

### Verification Commands
| Task | Proof Command | Expected Output |
|------|--------------|-----------------|

### TDD Sequence
1. [first test to write] -- covers [behavior]
2. [second test] -- covers [behavior]

Rules

• Always run bun run test to understand current test state before recommending or writing new tests
• Match existing test conventions -- do not introduce new test patterns
• Every test must have a clear "why" -- no tests for testing's sake
• Focus on testing behavior, not implementation details
• Verification commands must be runnable locally (no CI/CD dependencies)
• Prioritize tests that catch regressions over tests that verify happy paths
• Write comprehensive tests, not just coverage padding
