Flipper Test Utilities

flipper-test-utils is a library providing common testing utilities specifically designed for developing and testing Flipper plugins and components within the Flipper ecosystem. It is an integral part of the larger Flipper monorepo maintained by Facebook, currently at version 0.273.0. The package has a rapid release cadence, with updates typically aligning with the main Flipper desktop application releases (often weekly or bi-weekly). Its primary purpose is to facilitate isolated and integrated testing of Flipper plugins by offering functionalities like component rendering (often re-exporting or wrapping `@testing-library/react` utilities), mocking the Flipper client API, and providing helper functions for common testing scenarios. This allows developers to thoroughly test their plugins' UI, data interactions, and Flipper host communications without needing a full Flipper desktop environment.
