# Unit Tests Unit testing means testing individual units of code for their expected behaviour. Here we simulate every possible scenario of functions and ensure they behave as expected. ### Smart tests within minutes Testing all classes and functions increases code quality and better stability but is a time consuming task when done manually. Welltested AI allows you to cut this time and easily generate smart and exhaustive unit tests for your entire codebase within minutes. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
