name	generate-tests
description	Generate comprehensive test cases (dual-view) for a given backend or frontend file.

🎯 Generate Tests Skill

When to use: When the user asks you to "write tests for X" or during the implementation phase of a feature, to automatically generate rigorous dual-view tests based on .agent/rules/testing_guidelines.md.

📚 Skill Assets (Three-Layer Model)

1. Domain Library (library/)

• testing-standards.md: 测试规范（Mocking 准则、覆盖率要求、命名建议）。

2. Templates (prompts/)

• test-template.j2: Pytest 异步/同步测试模板。支持自动生成 Arrange-Act-Assert 结构。

3. Scripts (scripts/)

• test-runner.py: 自动化的单元测试运行器。生成测试代码后，务必运行此脚本进行闭环验证。

📝 Execution Steps (Enhanced)

Step 1: Analyze & Context Ingestion

• Identify if the file is a Python Backend Service, an API Route, or a React Frontend Component.
• Read library/testing-standards.md to ensure mock strategy aligns with project rules.

Step 2: Determine Mocking Strategy

• Apply the rules from the library to decide what dependencies to mock.
• Identify LLM calls, DB sessions, and External APIs.

Step 3: Generation via Template

• Fill the variables for prompts/test-template.j2.
• Create the test file at the mirror location (e.g., backend/tests/unit/...).

Step 4: Closed-loop Verification

• Run python .agent/skills/generate-tests/scripts/test-runner.py <path_to_test_file>.
• If tests fail, analyze output, fix the generated code, and re-run until passing.

Step 5: Final Output

• Provide the final test code along with a summary of covered cases.
