React Test Renderer versions 1.1.0 and 1.0.0 offer lightweight solutions for testing fully rendered React components, enabling developers to easily assert on the output of their components in a simulated environment. Both versions share a similar core purpose, providing an abstraction layer over React's rendering process specifically designed for testing. Key dependencies like object-assign for object manipulation remain consistent.
However, a notable difference lies in the supported React versions and the corresponding test utilities. Version 1.1.0 broadens compatibility by supporting React versions ^0.14.0 || ^15.0.0 and includes react-addons-test-utils with the same version range. This allows developers using older React versions to leverage the test renderer. In contrast, version 1.0.0 focuses exclusively on React 15.0.2 and its matching react-addons-test-utils version 15.0.2, offering a more targeted support for this specific React iteration.
The devDependencies are identical, using jsdom for emulating a browser environment and mocha for test execution. The updates made on 1.1.0 make it a better choice if you are on an older version of react, consider the differences in supported React versions when choosing the appropriate version for your project. Developers benefit from using react-test-renderer because it allows them to snapshot the state of the component and compare the output between different builds, this is extremely valuable during refactors and component updates.
