Test Planning Strategy
Test Scenario Matrix
| Type | Description | Example |
|---|---|---|
| Happy Path | Normal expected usage | Parse valid 80-byte record |
| Boundary Values | Edge of valid range | Balance = 0.00 and 99999.99 |
| Invalid Input | Outside valid range | Record length ≠ 80 |
| Error Conditions | Exceptions and errors | File not found, null input |
| Integration | Component interactions | Psam1 calls Psam2 |
Test Pyramid
code
/\ E2E (3-5 tests)
/ \ Integration (10-20 tests)
/ \ Unit (40-60 tests, fast & focused)
Coverage Goals by Component
| Priority | Component | Coverage | Test Types |
|---|---|---|---|
| P0 | Business Logic | 90%+ | Unit + Integration |
| P0 | Data Models | 95%+ | Unit |
| P1 | I/O Operations | 80%+ | Integration |
| P2 | Utilities | 70%+ | Unit |
Planning Checklist
- • List all public methods and classes
- • Identify happy path scenarios
- • List boundary values
- • Plan error scenarios
- • Determine what needs mocks vs real components
- • Estimate test count per component
- • Implement critical tests first
