verified May 27, 2026

setup-polly-jest provides a testing helper that integrates PollyJS, an HTTP recording, replaying, and stubbing tool, seamlessly into Jest and Jasmine test environments. It automatically manages the lifecycle of Polly instances for individual tests and suites, simplifying setup and teardown. The current stable version is 0.11.0, indicating it's actively maintained but pre-1.0, suggesting potential API changes. It differentiates itself by abstracting away much of the boilerplate associated with PollyJS in Jest, mirroring the convenience of built-in Mocha or QUnit PollyJS helpers. It also offers custom Jest environments (node and jsdom) to ensure compatibility with different Jest runner versions, particularly jest-circus, and handles recording name generation based on test structure.
