Is this skill specific to Python?

While the pattern is inspired by Python 'pytudes', the logic of using input/output pairs for specification is applicable to any programming language.

When should I avoid using this testing pattern?

Avoid this pattern when behavior is too complex to represent as simple pairs or when property-based testing is required to cover an exhaustive range of values.

What is the benefit of the example-driven testing pattern?

It treats examples as both formal specifications and executable tests, making the expected behavior of code clear, readable, and easy to verify.

How does this help with regression testing?

By maintaining a list of past inputs and their confirmed outputs, you can quickly re-verify function behavior after making changes to the codebase.

Security & Testing

Implements example-driven development by defining clear input-output pairs for robust unit testing and documentation.

Inspired by Peter Norvig's coding style, this skill equips Claude with patterns for example-driven development (EDD). It focuses on using concise test cases as specifications, representing inputs and expected outputs as data structures to ensure code clarity and reliability. This approach is particularly effective for documenting complex behavior, identifying edge cases, and creating regression tests for functions with discrete input/output relationships, ultimately making codebases more readable and pedagogical.
