Role in this project:Mobile Developer (iOS)
Mobile Developer (iOS)Contributions:5 commits, 1 PR, 3 comments in 1 day
Contributions summary:John's contributions focus on adapting the RxSwift library's testing framework to incorporate the new `DispatchQueueSchedulerQOS` enum introduced in the project. Their work involves modifying existing tests, specifically within the `Observable+BlockingTest`, `Observable+TimeTest`, and `Observable+ConcurrencyTest` files, to utilize and test the new QOS-based scheduling approach. They also updated `Driver+Test` and made the necessary changes to adopt the updated QOS mechanisms. This demonstrates a clear effort to align the test suite with the latest features and best practices of the library, including deprecation warnings for prior scheduling mechanisms.
