This repository aims to bridge the gap between JUnit 5 and Robolectric, enabling developers to leverage the benefits of both frameworks for unit testing Android applications. While Robolectric currently lacks a dedicated JUnit 5 extension, this project proposes a community-driven solution to achieve seamless integration.

The newest version!
