/cs-tests — Generate Tests from Code Paths

Auto-generate unit tests by analyzing execution paths through a function. Finds edge cases, branches, and error conditions automatically.

Usage

/cs-tests src/utils.py function calculate_tax
/cs-tests src/validation.py function validate_email
/cs-tests src/api.py function handle_request

How It Works

Extract — Get the function you want to test
Symbolic Execute — Run the code symbolically to explore all branches
- Finds path conditions (if/else, loops, exceptions)
- Identifies edge cases and dead code
Generate Tests — Create pytest test cases for each path
- Happy path (normal inputs)
- Error cases (invalid inputs)
- Edge cases (boundary values)
- Dead code detection

What You Get

A test file with:

✅ One test per execution path
✅ Different input types (valid, invalid, boundary)
✅ Exception handling tests
✅ pytest or unittest format (you choose)

Test Generation Framework

Supports:

pytest (recommended, modern)
unittest (legacy, standard library)

Example Output

def test_calculate_tax_normal():
    assert calculate_tax(100) == 10.0

def test_calculate_tax_zero():
    assert calculate_tax(0) == 0.0

def test_calculate_tax_negative_raises():
    with pytest.raises(ValueError):
        calculate_tax(-100)

Next Steps

Review the generated tests
Run them: pytest test_*.py
Adjust assertions if needed
Commit to your test suite

Pro Tip

Generate tests BEFORE refactoring to create a safety baseline:

/cs-tests src/legacy_code.py function complex_function
# Now safe to refactor—tests will catch breakage
/cs-refactor src/legacy_code.py function complex_function

See CLAUDE.md for the full test generation workflow.
