Eslint-plugin-jest version 21.0.2 is a minor patch release subsequent to version 21.0.0, both designed to enhance Jest testing within ESLint environments. Targeting developers seeking efficient and consistent Javascript and Typescript testing, these plugins provide rules specifically tailored for Jest's assertion library and testing structure.
The core functionality remains consistent between the two versions, offering a suite of linting rules aiding in writing cleaner, more maintainable Jest tests. This includes rules around consistent test descriptions, proper assertion usage, and avoiding common anti-patterns in Jest code. Both versions share the same peer dependency requirement of ESLint version 3.6 or higher, ensuring compatibility with established ESLint setups. They also operate under the BSD-3-Clause license, promoting open-source usage and contribution.
The primary difference lies in the release date and potentially bug fixes or minor rule adjustments. Version 21.0.2 was released on September 8, 2017, subsequent to version 21.0.0's release on September 4, 2017. Users migrating to version 21.0.2 can anticipate the same core linting capabilities as version 21.0.0, alongside increased stability. Because of the close release dates and the nature of semantic versioning, developers may find the upgrade valuable in guaranteeing a more dependable testing environment. For comprehensive details regarding the changes incorporated in version 21.0.2, consulting the project's commit history or release notes on the Jest GitHub repository (where the code of this plugin is hosted) is highly recommended.
