Summary of Changes

Hello @kabir, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves a NullPointerException that was occurring in a specific test case, JSONRPCHandlerTest.testOnMessageNewMessageSuccessMocks. The core issue was that a DoneCallback was not being correctly initialized when an EventConsumer was mocked, leading to the NPE. The fix involves explicitly instructing the mock to call the real method for creating this callback, thereby ensuring its proper instantiation. Additionally, a minor cleanup was performed by removing an unused import.

Highlights

  • Test Fix: Addressed a NullPointerException in the JSONRPCHandlerTest.testOnMessageNewMessageSuccessMocks test method by ensuring the DoneCallback is properly initialized during the mocking of EventConsumer.
  • Code Cleanup: Removed an unused java.util.ArrayList import from EnhancedRunnable.java.

Code Review

The pull request correctly addresses a NullPointerException in testOnMessageNewMessageSuccessMocks. I've added a suggestion to improve the formatting for readability.

Important: The same bug exists in other tests within JSONRPCHandlerTest.java which also use mockConstruction on EventConsumer but were not updated. To ensure test suite stability, please apply the same fix to testOnMessageNewMessageWithExistingTaskSuccessMocks, testOnMessageErrorMocks, testOnMessageStreamNewMessageSuccessMocks, and testOnMessageStreamNewMessageExistingTaskSuccessMocks.

The removal of the unused import in EnhancedRunnable.java is a good cleanup.

For better readability, it's good practice to format lambda bodies with multiple statements on separate lines with proper indentation. This makes the code easier to read and maintain.

                (mock, context) -> {
                    Mockito.doReturn(ZeroPublisher.fromItems(wrapEvent(MINIMAL_TASK))).when(mock).consumeAll();
                    Mockito.doCallRealMethod().when(mock).createAgentRunnableDoneCallback();
                })){
