   Hi TU-Zhong, I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

   Issue: System.out.println output does not appear in the Test Results panel when running tests, only in the Debug Console.

   Workarounds & Suggestions

   • Update to the latest Java Test Runner extension (problems with stdout in panel were reported in v0.24.2).
   • Open the Test Runner output channel:
     1. View → Output
     2. Select “Test Runner” (or “Java Test Runner”) from the dropdown. Your println statements are logged there, not in the Test Results UI.
   • Consider using a logging framework (e.g. SLF4J/log4j) instead of System.out.println, which integrates better with VS Code’s test output.
