pytest Test Framework
Purpose
Provide pytest test execution and generation for Python projects, supporting:
- Test file generation from templates
- Test execution with structured output
- Fixtures and parametrized tests
- Mock and monkeypatch support
Usage
Generate Test File
python generate-test.py \
--source src/calculator.py \
--output tests/test_calculator.py \
--type unit \
--description "Calculator fails to handle division by zero"
Execute Tests
python run-test.py \
--file tests/test_calculator.py \
--config pytest.ini
Output Format
Test Generation
{
"success": true,
"testFile": "tests/test_calculator.py",
"testCount": 3,
"template": "unit-test"
}
Test Execution
{
"success": false,
"passed": 2,
"failed": 1,
"total": 3,
"duration": 0.234,
"failures": [
{
"test": "test_divide_by_zero",
"error": "AssertionError: Expected ZeroDivisionError",
"file": "tests/test_calculator.py",
"line": 15
}
]
}
Integration
Used by deep-debugger for Python project testing:
- Invoke test-detector to identify pytest
- Invoke generate-test.py to create failing test
- Invoke run-test.py to validate test fails
- Re-run after fix to verify passing
