Which testing frameworks are supported by this skill?

Smart Assertion Helper currently supports Vitest, Jest, and Pytest, providing tailored templates for JavaScript, TypeScript, and Python environments.

Does it support testing for errors and exceptions?

Absolutely. It analyzes function logic to identify potential failure points and generates assertions for both synchronous exceptions and asynchronous rejections.

How does this help with boundary testing?

The skill automatically detects numeric and string constraints to suggest specific boundary value tests, ensuring your code handles minimum, maximum, and invalid inputs correctly.

Can it handle complex nested objects in tests?

Yes, the skill includes a recursive logic engine that generates deep object comparisons and partial matches for complex data structures.

Can this skill verify side effects like API calls or state changes?

Yes, it can generate assertions for various side effects including console output, event emitters, state modifications, and mock function calls.

Security & Testing

Analyzes code logic to automatically generate precise, multi-framework test assertions for unit and integration testing.

Smart Assertion Helper is a specialized Claude Code skill designed to streamline the testing process by analyzing function signatures, return values, and side effects. It intelligently constructs robust assertions across popular frameworks like Jest, Vitest, and Pytest. Whether you are dealing with complex nested objects, asynchronous operations, or verifying mock calls, this skill ensures your tests are accurate, maintainable, and cover critical boundary conditions without the manual overhead of writing boilerplate validation code.
