自动化代码质量测试

🇨🇳中文介绍

TDD 指南

用于生成测试、分析覆盖率，并指导 Jest、Pytest、JUnit 和 Vitest 的红-绿-重构工作流的测试驱动开发技能。

能力

能力	描述
测试生成	将需求或代码转换为具有适当结构的测试用例
覆盖率分析	解析 LCOV/JSON/XML 报告，识别缺口，确定修复优先级
TDD 工作流	通过验证指导红-绿-重构循环
框架适配器	为 Jest、Pytest、JUnit、Vitest、Mocha 生成测试
质量评分	评估测试隔离性、断言、命名，检测测试异味
夹具生成	创建真实的测试数据、模拟对象和工厂

工作流

从代码生成测试

提供源代码（TypeScript、JavaScript、Python、Java）
指定目标框架（Jest、Pytest、JUnit、Vitest）
使用需求运行 test_generator.py

工具	用途	用法
`test_generator.py`	从代码/需求生成测试用例	`python scripts/test_generator.py --input source.py --framework pytest`
`coverage_analyzer.py`	解析和分析覆盖率报告	`python scripts/coverage_analyzer.py --report lcov.info --threshold 80`
`tdd_workflow.py`	指导红-绿-重构循环	`python scripts/tdd_workflow.py --phase red --test test_auth.py`
`framework_adapter.py`	在框架之间转换测试	`python scripts/framework_adapter.py --from jest --to pytest`
`fixture_generator.py`	生成测试数据和模拟对象	`python scripts/fixture_generator.py --entity User --count 5`
`metrics_calculator.py`	计算测试质量指标	`python scripts/metrics_calculator.py --tests tests/`
`format_detector.py`	检测语言和框架	`python scripts/format_detector.py --file source.ts`
`output_formatter.py`	为 CLI/桌面/CI 格式化输出	`python scripts/output_formatter.py --format markdown`

范围	详情
单元测试焦点	集成测试和端到端测试需要不同的模式
静态分析	无法执行测试或测量运行时行为
语言支持	最适合 TypeScript、JavaScript、Python、Java
报告格式	仅限 LCOV、JSON、XML；其他格式需要转换
生成的测试	提供脚手架；复杂逻辑需要人工审查

TDD Guide

Test-driven development skill for generating tests, analyzing coverage, and guiding red-green-refactor workflows across Jest, Pytest, JUnit, and Vitest.

Capabilities

Tools
Input Requirements
Limitations

Capabilities

Capability	Description
Test Generation	Convert requirements or code into test cases with proper structure
Coverage Analysis	Parse LCOV/JSON/XML reports, identify gaps, prioritize fixes
TDD Workflow	Guide red-green-refactor cycles with validation
Framework Adapters	Generate tests for Jest, Pytest, JUnit, Vitest, Mocha
Quality Scoring	Assess test isolation, assertions, naming, detect test smells
Fixture Generation	Create realistic test data, mocks, and factories

Workflows

Generate Tests from Code

Provide source code (TypeScript, JavaScript, Python, Java)
Specify target framework (Jest, Pytest, JUnit, Vitest)
Run test_generator.py with requirements
Review generated test stubs
Validation: Tests compile and cover happy path, error cases, edge cases

Analyze Coverage Gaps

Generate coverage report from test runner (npm test -- --coverage)
Run coverage_analyzer.py on LCOV/JSON/XML report
Review prioritized gaps (P0/P1/P2)
Generate missing tests for uncovered paths
Validation: Coverage meets target threshold (typically 80%+)

TDD New Feature

Write failing test first (RED)
Run tdd_workflow.py --phase red to validate
Implement minimal code to pass (GREEN)
Run tdd_workflow.py --phase green to validate
Refactor while keeping tests green (REFACTOR)
Validation: All tests pass after each cycle

Tools

Tool	Purpose	Usage
`test_generator.py`	Generate test cases from code/requirements	`python scripts/test_generator.py --input source.py --framework pytest`
`coverage_analyzer.py`	Parse and analyze coverage reports	`python scripts/coverage_analyzer.py --report lcov.info --threshold 80`
`tdd_workflow.py`	Guide red-green-refactor cycles	`python scripts/tdd_workflow.py --phase red --test test_auth.py`

Input Requirements

For Test Generation:

Source code (file path or pasted content)
Target framework (Jest, Pytest, JUnit, Vitest)
Coverage scope (unit, integration, edge cases)

For Coverage Analysis:

Coverage report file (LCOV, JSON, or XML format)
Optional: Source code for context
Optional: Target threshold percentage

For TDD Workflow:

Feature requirements or user story
Current phase (RED, GREEN, REFACTOR)
Test code and implementation status

Limitations

Scope	Details
Unit test focus	Integration and E2E tests require different patterns
Static analysis	Cannot execute tests or measure runtime behavior
Language support	Best for TypeScript, JavaScript, Python, Java
Report formats	LCOV, JSON, XML only; other formats need conversion
Generated tests	Provide scaffolding; require human review for complex logic

When to use other tools:

E2E testing: Playwright, Cypress, Selenium
Performance testing: k6, JMeter, Locust
Security testing: OWASP ZAP, Burp Suite
