QA Lead Agent (Deprecated)

note

The qa-lead skill has been removed from the core plugin. Use testing:qa instead, which provides the same QA strategy and test coverage capabilities.

The QA Engineer Agent (testing:qa) is SpecWeave's AI-powered Quality Assurance specialist that handles test strategy, test case generation, and coverage validation.

What It Does

Key responsibilities:

• 🧪 Test strategy - Defines testing approach and coverage targets
• 📝 Test case generation - Creates comprehensive test cases
• 📊 Coverage validation - Ensures coverage targets are met
• ✅ Quality gates - Validates work meets quality standards
• 🔍 Edge case identification - Finds boundary conditions

Test Generation

The QA Lead Agent creates tests in BDD format:

## Test Cases for AuthService

### TC-001: Valid Login
**Given** a registered user with valid credentials
**When** they submit the login form
**Then** they receive a JWT token and are redirected to dashboard

### TC-002: Invalid Password
**Given** a registered user with invalid password
**When** they submit the login form
**Then** they see an error message "Invalid credentials"

### TC-003: Rate Limiting
**Given** a user who has failed login 5 times
**When** they try to login again
**Then** they see "Too many attempts, try again in 1 minute"

Coverage Targets

Default coverage targets by test type:

Test Type	Target	Purpose
Unit Tests	90%	Business logic
Integration Tests	85%	Component interaction
E2E Tests	100% critical paths	User flows

Commands

Check Test Coverage

npx vitest run 0001

Output:

📊 Test Coverage Report: 0001-user-authentication

Per-Task Coverage:
  T-001: AuthService      ✅ 95% (target: 90%)
  T-002: JWTManager       ✅ 92% (target: 90%)
  T-003: PasswordHasher   ⚠️ 85% (target: 90%)

AC-ID Coverage:
  AC-US1-01 ✅ Covered (auth.test.ts:42)
  AC-US1-02 ✅ Covered (auth.test.ts:78)
  AC-US1-03 ⚠️ Missing tests

Overall: 89% (target: 88%) ✅

Recommendations:
- Add tests for AC-US1-03 (remember me checkbox)
- Increase PasswordHasher coverage (+5%)

Test Pyramid Enforcement

The QA Lead Agent enforces the test pyramid:

        /\
       /  \     E2E Tests (few, slow, expensive)
      /----\
     /      \   Integration Tests (some)
    /--------\
   /          \  Unit Tests (many, fast, cheap)
  --------------

Guidance:

• Write many fast unit tests
• Write some integration tests
• Write few E2E tests (critical paths only)
