QE Test Generation Skill

QE Test Generation

Purpose

Guide the use of v3's AI-powered test generation capabilities including pattern-based test synthesis, multi-framework support, and intelligent test case derivation from code analysis.

Activation

When generating tests for new code
When improving test coverage
When migrating tests between frameworks
When applying TDD patterns
When generating edge case tests

Quick Start

# Generate unit tests for a file
aqe test generate --file src/services/UserService.ts --framework jest

# Generate tests with coverage target
aqe test generate --scope src/api/ --coverage 90 --type unit

# Generate integration tests
aqe test generate --file src/controllers/AuthController.ts --type integration

# Generate from patterns
aqe test generate --pattern repository --target src/repositories/

Agent Workflow

// Spawn test generation agents
Task("Generate unit tests", `
  Analyze src/services/PaymentService.ts and generate comprehensive Jest tests.
  Include:
  - Happy path tests for all public methods
  - Edge cases and boundary conditions
  - Error handling scenarios
  - Mock external dependencies
  Output to tests/unit/services/PaymentService.test.ts
`, "qe-test-generator")

// Pattern-based generation
Task("Apply test patterns", `
  Scan src/repositories/ and apply repository test pattern:
  - CRUD operation tests
  - Query builder tests
  - Transaction tests
  - Connection error handling
`, "qe-pattern-matcher")

Test Generation Strategies

1. Code Analysis Based

await testGenerator.analyzeAndGenerate({
  source: 'src/services/OrderService.ts',
  analysis: {
    methods: true,
    branches: true,
    dependencies: true,
    errorPaths: true
  },
  output: {
    framework: 'jest',
    style: 'describe-it',
    assertions: 'expect'
  }
});

2. Pattern-Based Generation

await testGenerator.applyPattern({
  pattern: 'service-layer',
  targets: ['src/services/*.ts'],
  customizations: {
    mockStrategy: 'jest.mock',
    asyncHandling: 'async-await',
    errorAssertion: 'toThrow'
  }
});

3. Coverage-Driven Generation

await testGenerator.fillCoverageGaps({
  coverageReport: 'coverage/lcov.info',
  targetCoverage: 90,
  prioritize: ['uncovered-branches', 'error-paths'],
  maxTests: 50
});

Framework Support

| Framework | Unit | Integration | E2E | Mocking | |-----------|------|-------------|-----|---------| | Jest | ✅ | ✅ | ⚠️ | jest.mock | | Vitest | ✅ | ✅ | ⚠️ | vi.mock | | Mocha | ✅ | ✅ | ❌ | sinon | | Pytest | ✅ | ✅ | ❌ | pytest-mock | | JUnit | ✅ | ✅ | ❌ | Mockito |

Test Quality Checks

quality_checks:
  assertions:
    minimum_per_test: 1
    meaningful: true

  isolation:
    no_shared_state: true
    proper_setup_teardown: true

  naming:
    descriptive: true
    follows_convention: true

  coverage:
    branches: 80
    statements: 85
