Jest JUnit Reporter (Legacy)

This entry describes `jest-junit-reporter` version 1.1.0, a utility for generating JUnit XML test reports from Jest test results. Published 9 years ago, this specific package is effectively abandoned and is no longer maintained. It leverages Jest's `testResultsProcessor` configuration option to intercept test outcomes and format them into a `test-results.xml` file. For any new projects or migrations, the actively maintained and recommended alternative is `jest-junit` (currently at version 16.0.0), which offers more features, better compatibility with modern Jest versions, and uses the `reporters` array configuration (as `testResultsProcessor` is deprecated by Jest itself). This legacy reporter's configuration is limited to environment variables like `TEST_REPORT_PATH` and `TEST_REPORT_FILENAME` for output location and filename. Due to its age, it may have compatibility issues with newer Node.js or Jest versions.
