Jest-fetch-mock is a lightweight and useful library designed to simplify testing JavaScript code that relies on the fetch API within the Jest testing framework. Versions 1.1.1 and 1.2.0, while seemingly similar, offer distinct release timelines. Version 1.2.0 was released on July 5th, 2017, while version 1.1.1 precedes it, having been released on April 22nd, 2017. Both versions share the same core functionality of mocking the fetch API for Jest, allowing developers to simulate network requests and responses in a controlled environment during testing. This ensures predictable and reliable test outcomes without actually hitting external servers.
Both versions depend on whatwg-fetch version 1.0.0, indicating a shared foundation for implementing the fetch API. Developers can use jest-fetch-mock to isolate their code, verify request parameters, and mock successful or erroneous responses, improving test coverage and application robustness. The small update (minor version update) indicates that the newer version 1.2.0 should include several bug fixes and probably some small features, but without breaking backward compatibility or adding major new features. For developers using earlier versions, upgrading to 1.2.0 is thus recommended to benefit from the accumulated improvements and fixes. The library is licensed under the MIT license promoting open-source contributions and usage.
