Test Strategy Planning

Test Strategy Planning

When to Use This Skill

Use this skill when:

• Test Strategy Planning tasks - Working on create comprehensive test strategy documents following ieee 829 structure. plan test approach, scope, resources, and success criteria for software projects
• Planning or design - Need guidance on Test Strategy Planning approaches
• Best practices - Want to follow established patterns and standards

Overview

A test strategy defines the overall approach to testing a software system. It establishes the scope, objectives, resources, schedule, and success criteria for testing activities before development begins.

### 3.3 Risk-Based Prioritization

| Risk Area | Likelihood | Impact | Test Priority |
|-----------|------------|--------|---------------|
| [Payment processing] | Medium | High | P1 - Extensive |
| [User authentication] | Low | High | P1 - Extensive |
| [Reporting] | Low | Medium | P2 - Standard |
| [Admin settings] | Low | Low | P3 - Basic |

## 4. Test Environment

### 4.1 Environment Strategy

| Environment | Purpose | Data | Refresh Cycle |
|-------------|---------|------|---------------|
| Dev | Developer testing | Synthetic | On-demand |
| QA | Functional testing | Masked production | Weekly |
| Staging | Pre-prod validation | Production clone | Before release |
| Performance | Load testing | Scaled synthetic | Before release |

### 4.2 Infrastructure Requirements
- [Server specifications]
- [Network requirements]
- [Third-party service access]

## 5. Test Data

### 5.1 Data Strategy
- **Synthetic data**: Generated for unit/integration tests
- **Masked production data**: For realistic QA testing
- **Performance data**: Scaled to production volumes

### 5.2 Data Privacy
- [Anonymization requirements]
- [PII handling procedures]
- [Data retention policies]

## 6. Entry and Exit Criteria

### 6.1 Entry Criteria
- [ ] Requirements reviewed and approved
- [ ] Test environment available
- [ ] Test data prepared
- [ ] Test cases reviewed
- [ ] Build deployed to test environment

### 6.2 Exit Criteria
- [ ] All P1 test cases executed
- [ ] No critical defects open
- [ ] Code coverage ≥ 80%
- [ ] Performance targets met
- [ ] Security scan passed

## 7. Defect Management

### 7.1 Severity Levels

| Severity | Description | Resolution Time |
|----------|-------------|-----------------|
| Critical | System unusable | 4 hours |
| High | Major feature broken | 1 day |
| Medium | Feature degraded | 1 week |
| Low | Minor issue | Next release |

### 7.2 Defect Workflow
1. Tester logs defect with reproduction steps
2. Dev lead triages and assigns
3. Developer fixes and unit tests
4. Tester verifies fix
5. Defect closed or reopened

## 8. Test Deliverables

| Deliverable | Audience | Frequency |
|-------------|----------|-----------|
| Daily Test Status | Dev team | Daily |
| Test Summary Report | Management | Per sprint |
| Defect Metrics | All stakeholders | Weekly |
| Release Test Report | Release team | Per release |

## 9. Roles and Responsibilities

| Role | Responsibilities |
|------|------------------|
| Test Lead | Strategy, planning, reporting |
| QA Engineer | Test design, execution, defects |
| Developer | Unit tests, test support |
| Product Owner | Acceptance criteria, UAT |

## 10. Schedule

| Phase | Start | End | Milestone |
|-------|-------|-----|-----------|
| Test Planning | [Date] | [Date] | Strategy approved |
| Test Design | [Date] | [Date] | Test cases ready |
| Test Execution | [Date] | [Date] | All tests run |
| UAT | [Date] | [Date] | Sign-off |

## 11. Risks and Mitigations

| Risk | Probability | Impact | Mitigation |
|------|-------------|--------|------------|
| Environment unavailable | Medium | High | Backup environment ready |
| Resource shortage | Low | Medium | Cross-training |
| Requirement changes | High | Medium | Change control process |

Test Approach Patterns

Risk-Based Testing

Prioritize testing based on:

1. Business criticality: Revenue-impacting features first
2. Technical complexity: Complex components need more testing
3. Change frequency: Frequently changed areas need regression focus
4. Defect history: Bug-prone areas need more attention

Shift-Left Testing

Move testing earlier in the SDLC:

• Requirements testing (review for testability)
• Design testing (architecture review, threat modeling)
• Static analysis (before code review)
• Unit testing (during development)

Continuous Testing

Integrate testing into CI/CD:

• Pre-commit: Linting, unit tests
• PR: Integration tests, code coverage
• Merge: Full regression, security scan
• Deploy: Smoke tests, synthetic monitoring

Quality Metrics

Coverage Metrics

Execution Metrics

.NET Example: Test Strategy Configuration

// Directory.Build.props - Shared test configuration
<Project>
  <PropertyGroup>
    <TreatWarningsAsErrors>true</TreatWarningsAsErrors>
    <CollectCoverage>true</CollectCoverage>
    <CoverletOutputFormat>cobertura</CoverletOutputFormat>
    <Threshold>80</Threshold>
  </PropertyGroup>
</Project>

Integration Points

Inputs from:

• Requirements documents → Test scope
• Architecture documents → Test levels
• Risk assessments → Test prioritization

Outputs to:

• test-pyramid-design skill → Pyramid ratios
• test-case-design skill → Test techniques
• CI/CD pipeline → Automation scope
