React Test Renderer versions 16.13.0 and 16.12.0 offer snapshot testing capabilities for React components, enabling developers to efficiently verify UI consistency across updates. While both share a common core purpose and several dependencies like react-is, prop-types, and object-assign, and peer dependency of react, there are subtle yet important distinctions.
The key difference lies in the scheduler dependency. Version 16.13.0 utilizes scheduler version ^0.19.0, a newer iteration compared to version 16.12.0, which relies on scheduler ^0.18.0. This upgrade to the scheduler likely incorporates performance improvements, bug fixes, and potentially new scheduling strategies that impact how React renders and updates components. Developers may experience smoother interactions and optimized rendering behavior with the newer version.
Another notable difference can be found in the unpackedSize. Version 16.13.0 has a smaller footprint (1351265) compared to 16.12.0 (1509211). Although it does not seem like the package size would have been significantly reduced, it is interesting to note that after 4 months of development, the package size was reduced.
Furthermore, version 16.13.0 was released on February 26, 2020, approximately four months after version 16.12.0, released on November 14, 2019. This temporal gap implies bug fixing and probably new React features from the core team. For developers, choosing 16.13.0 offers the benefit of the latest refinements and potential performance gains in the React rendering pipeline, contributing to a more robust and efficient testing process.
