JUnit 5 @Suite classes do not update status icons in Test Explorer

[Biyakuga]

Description

When running a JUnit 5 Test Suite (using @suite and @SelectPackages), the tests execute successfully, but the VS Code Test Explorer UI and Test Results panel do not update to show the "Passed" state (green checkmarks). The Suite class often remains in a "running" or "unknown" state visually or does not expand to show the tests being run, even though the Output console confirms execution.

Reproduce

Steps to reproduce the behavior:

1. Create a simple JUnit 5 project with junit-platform-suite.
2. Create a Suite class:
   @Suite @SelectPackages("com.example.tests") public class MyTestSuite { }
3. Click the "Run Test" (Play icon) next to the MyTestSuite class in the Test Explorer.
4. Observe that the tests run (output is generated), but the UI does not show checkmarks for the Suite.

Expected behavior

The Test Explorer should visually reflect that the Suite and its contained tests have passed (green checkmarks), similar to how individual @test classes behave.

Current behavior

• The tests execute (verified via console output).
• The Test Explorer sidebar does not show checkmarks for the Suite.
• The Output tab ("Test Output") shows raw Eclipse protocol messages (e.g., %TSTTREE, %TESTS, %TESTE) instead of a clean summary or UI update.

Image for visualization:

As you can see in the Test Results Panel" no checkmark ✅ icon or fail icon only grey arrow the same behavior happens in the "Test Explorer Sidebar"

Sample Output (Raw Protocol seen in Output tab)
%TSTTREE54,com.example.MyTest,true,2,false,3,MyTest,,[engine:junit-jupiter]/[class:com.example.MyTest] %TESTS 61,shouldDoSomething(com.example.MyTest) %TESTE 61,shouldDoSomething(com.example.MyTest)

Environment

VS Code Version 1.108.1
Windows 11 latest stable version

Hi @Biyakuga, 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.

The VS Code Java Test Runner currently doesn’t fully update Test Explorer status for JUnit 5 @suite classes. You can try the following workarounds:

• Add the JUnit Platform Suite Engine to your classpath so the suite container reports results properly:

  <dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-suite-engine</artifactId>
    <version>1.14.2</version>
  </dependency>

• Update to the latest Test Runner for Java extension in VS Code (check for updates in the Extensions view).
• Enable debug logging for the test runner to inspect protocol messages:

  // settings.json
  "java.test.logLevel": "debug"

• If the issue persists after the above, please file a new bug on the Java Test Runner repo: https://github.com/microsoft/vscode-java-test/issues/new?template=bug_report.md

The team will respond to your issue shortly. I hope these suggestions are helpful in the meantime. If this comment helped you, please give it a 👍. If the suggestion was not helpful or incorrect, please give it a 👎. Your feedback helps us improve!

I mistakenly closed the issue, but the problem is still occurring. I have verified this across several environments and observed the same result. There is no indication of whether the test suite has passed or failed.

In IntelliJ, however, it displays a checkmark (✅).
