@nathanielfinkgapmaps Thanks for reporting this.
This should be fixed by Test Runner for Java
0.46.0. Please update Test Runner for Java to0.46.0or newer together withredhat.java1.55.0or newer.I verified this combination with a plain Eclipse Java project using
junit-platform-console-standalone-1.13.4.jar: tests are discovered correctly and classified as JUnit 5.albertodlc commentedon Jun 30, 2026
This fix works. Just to take into account, if you are using VScodium with a non Microsoft marketplace the last version of the Test runner is 0.45 BUT the
Language Support for Java(TM) by Red Hatis the last one (1.55.0). So you must update the Java Test runner version manually or just revert to the previous version and wait until both are updated.mdakash472452-afk commentedon Jul 8, 2026

@datho7561 This has been fixed in Test Runner for Java
0.46.0. The reporter's scenario works withredhat.java1.55.0or newer together withvscjava.vscode-java-test0.46.0or newer, and another user has confirmed the fix as well.The remaining concern mentioned above was that some non-Microsoft marketplaces, such as Open VSX, were still serving Test Runner
0.45.0; users on those marketplaces need to update the test extension manually or temporarily roll backredhat.javauntil both versions are available.I think we can close this issue as completed.
