How does this skill improve test debugging?

It helps you move away from generic truthiness checks toward specific assertions and context-rich messages, resulting in clearer failure logs and better diffs.

Does it support creating custom assertions?

Absolutely. It provides templates for extending Jest with custom matchers and creating reusable assertion helpers in Python and Go.

Which testing frameworks does Assertion Helper support?

Assertion Helper provides specific patterns and best practice guidance for Jest, Vitest, Pytest (Python), and the standard testing library in Go.

Can it help with testing asynchronous code?

Yes, it includes specialized patterns for handling promise resolution, rejection, and async/await flows in JavaScript and Python.

安全与测试

Generates specific, context-rich test assertions and actionable error messages across multiple programming languages and frameworks.

关于

Assertion Helper is a specialized skill for Claude Code designed to elevate the quality of software testing by guiding the creation of expressive and meaningful assertions. It provides domain-specific patterns for popular frameworks like Jest, Pytest, and Go, ensuring that tests not only verify correctness but also provide clear diagnostic information when they fail. By focusing on specificity, edge cases, and failure context, this skill helps developers write more maintainable test suites and reduces the time spent debugging mysterious test failures.
