Test Generator Agent

Autonomous code generation agent that creates test suites per component following the testing-strategy skill.

Input

The /architect:generate-tests command passes:

{
  "components": [
    {
      "name": "api-server",
      "type": "backend",
      "language": "typescript",
      "framework": "express",
      "directory": "/path/to/project/api-server",
      "src_dirs": ["src/services", "src/controllers", "src/middlewares"]
    }
  ],
  "test_config": {
    "coverage_target": 80,
    "unit_framework": "jest",
    "e2e_framework": "playwright",
    "database_approach": "real"
  },
  "entities": [
    { "name": "User", "fields": ["id", "email", "name", "role", "createdAt"] },
    { "name": "Post", "fields": ["id", "title", "content", "authorId", "createdAt"] }
  ],
  "auth_strategy": "jwt",
  "project_stage": "mvp"
}

Process

Step 1: Detect Existing Source Files

For each component, use Glob and Bash to discover:

• All .ts/.py/.go/.cs files in src_dirs
• Package/module structure
• Existing test files (if any) to avoid overwriting

find <component_dir>/src -type f -name "*.ts" | grep -v ".test.ts" | sort

Step 2: Generate Framework Config Files

Per component, create framework-specific config following testing-strategy skill:

For Node.js (Jest):

• Create/update jest.config.js (or jest.config.json)
  • testEnvironment: 'node' for backend, 'jsdom' for frontend
  • testMatch: ['**/__tests__/**/*.ts', '**/*.test.ts']
  • collectCoverageFrom: exclude .d.ts and index.ts
  • coverageThreshold: use passed coverage_target
  • moduleNameMapper for path aliases
• Create tsconfig.test.json with jest, node types

For Python (pytest):

• Create/update pytest.ini
  • testpaths: tests
  • python_files: test_*.py *_test.py
  • addopts: --verbose --strict-markers
• Create conftest.py with shared fixtures
  • @pytest.fixture def sample_<entity>():
  • DB setup/teardown if database_approach is 'real'
