AI Unit Test Generator

Paste a function or class and I'll generate unit tests for it. Mention your testing framework (pytest, Jest, JUnit) if you have a preference.

Design useful tests

Provide the implementation, expected behavior and test framework. Include a failure case you want to prevent.

Example prompt and checks

Try this prompt

Using pytest, propose boundary and error tests for a function that rejects negative quantities. Explain what each test protects.

Check the answer

Run the tests and confirm that a deliberately broken implementation fails. Mock external services; avoid tests that merely repeat the code.

Prepared by the AskAI Editorial Team (see About AskAI.free). These examples illustrate how to ask a question; they are not records of a measured model test.
