What is the primary benefit of inline testing?

Inline testing keeps tests close to the implementation, making them easier to maintain and ensuring they serve as live documentation for how the code functions.

When should I avoid using this skill?

Avoid inline tests for large-scale production suites that require strict test isolation or when your CI/CD environment expects tests in a specific directory like /tests.

Does this skill only work for Python?

The pattern provided is optimized for Python using the main block idiom, but the general philosophy of co-locating tests for documentation can be adapted to other languages.

How does this improve Claude's output?

It encourages Claude to think about edge cases and structural integrity immediately after writing logic, leading to more robust and self-verifying code.

セキュリティとテスト

Implements Norvig-style inline testing patterns to co-locate tests with code for instant verification and documentation.

This skill guides Claude to follow the Norvig 'verify-with-inline-tests' pattern, where unit tests and structural invariants are placed directly within the source file. By using the 'if __name__ == "__main__":' idiom, tests serve as executable documentation and self-contained validation for single-file modules or utility scripts. This approach is ideal for rapid development, algorithmic challenges, and small libraries where maintaining a separate test suite would add unnecessary friction or overhead.
