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 });
