Jest-when is a powerful library that enhances Jest's mocking capabilities by allowing developers to define complex mock behavior with ease. It provides a fluent API for setting up mock responses based on specific input parameters, making it ideal for testing scenarios where mocking behavior needs to be dynamic and conditional. Jest-when simplifies the process of creating mock functions with precise control over return values and behaviors.

Compared to traditional Jest mocking methods, Jest-when offers a more intuitive and declarative approach, reducing the boilerplate code required for setting up mock responses. It is actively maintained and recommended for Jest users looking to streamline their mocking setup.
