How does it handle edge cases?

The skill systematically analyzes inputs to identify boundary values, null/undefined cases, and invalid types to ensure your code is resilient against unexpected data.

Does it support Test-Driven Development (TDD)?

Absolutely. The skill is designed to follow TDD principles, helping you define test cases and expected outcomes before or alongside implementation.

Which programming languages are supported by this skill?

While the logic and principles are language-agnostic, the skill provides optimized patterns and examples for Python (pytest) and JavaScript (Vitest/Jest).

Can this skill help with mocking external APIs?

Yes, it includes specific strategies for mocking and stubbing external dependencies like databases, file systems, and third-party APIs to ensure tests remain fast and isolated.
