Test Strategy Design

Purpose

Create a comprehensive test strategy that defines testing objectives, scope, types, tools, environments, and success criteria aligned with project requirements and quality goals.

When to Use

• Project initiation
• Major release planning
• Test approach changes
• Quality gate definition

Prerequisites

• Requirements documented
• NFRs defined
• Architecture understood
• Risk assessment available

Process

Step 1: Define Test Objectives

Objectives:
- Quality goals
- Risk mitigation
- Compliance requirements
- Coverage targets

Step 2: Determine Test Scope

In scope:
- Features to test
- Test types required
- Environments needed

Out of scope:
- Explicitly excluded items
- Deferred testing

Step 3: Select Test Types

Test pyramid:
- Unit tests (70%)
- Integration tests (20%)
- E2E tests (10%)

Additional:
- Security testing
- Performance testing
- Accessibility testing
- Compatibility testing

Step 4: Define Test Environment

Environments:
- Local development
- CI/CD pipeline
- Staging
- Production smoke

Step 5: Create Strategy Document

Document includes:
- Objectives and scope
- Test types and coverage
- Tools and frameworks
- Environment strategy
- Success criteria
- Roles and responsibilities

StudyAbroad-Specific Considerations

• GDPR compliance testing required
• External API mocking essential
• OAuth2 flow testing
• Multi-step form testing
• Document upload testing

Integration Points

• Orchestrator: Gate validation input
• Developer Agent: Test implementation coordination
• Security Agent: Security test planning

Examples

Test Strategy - StudyAbroad-v1

1. OBJECTIVES
   - Ensure 80% code coverage minimum
   - Zero critical/high severity bugs in production
   - GDPR compliance verification
   - Performance meets NFRs (page load <3s, API <500ms)
   - Accessibility WCAG 2.1 AA compliance

2. TEST SCOPE

   In Scope:
   - All user-facing features
   - API endpoints
   - Database operations
   - Authentication flows
   - External API integrations
   - GDPR features
   
   Out of Scope:
   - Third-party library internals
   - External API internal behavior
   - Admin features (Phase 2)

3. TEST TYPES

   Test Pyramid:
   ┌─────────────┐
   │    E2E     │ 10% - Critical user journeys
   │    (10)    │
   ├─────────────┤
   │ Integration │ 20% - API, database, services
   │    (50)     │
   ├─────────────┤
   │    Unit     │ 70% - Components, functions
   │   (200+)    │
   └─────────────┘

   Additional Testing:
   - Security: OWASP Top 10, auth testing
   - Performance: Load testing (10K concurrent)
   - Accessibility: Automated + manual audit
   - Compatibility: Chrome, Firefox, Safari, Edge

4. TEST TOOLS

   | Type | Tool | Purpose |
   |------|------|---------|
   | Unit | Jest | JS/TS unit tests |
   | Component | Testing Library | React components |
   | Integration | Supertest | API testing |
   | E2E | Playwright | Browser automation |
   | Security | OWASP ZAP | Security scanning |
   | Performance | k6 | Load testing |
   | Accessibility | axe-core | A11y testing |
   | Mocking | MSW | API mocking |

5. ENVIRONMENTS

   | Env | Purpose | Data |
   |-----|---------|------|
   | Local | Development | Fixtures |
   | CI | Automated tests | Fixtures |
   | Staging | Integration | Anonymized |
   | Prod | Smoke tests | Production |

6. SUCCESS CRITERIA

   Gate Requirements:
   - GATE-5: 80% unit coverage, all unit tests pass
   - GATE-6: All integration/E2E pass, security scan clean
   - GATE-7: Performance NFRs met, accessibility audit pass

7. ROLES

   - Test Manager: Strategy, planning, reporting
   - Developer Agent: Unit tests, integration tests
   - Security Agent: Security test execution
   - DevOps Agent: CI/CD test integration

Validation

• All requirements have test approach
• Coverage targets defined
• Tools selected and justified
• Environments specified
• Success criteria measurable
