Missing run test Icon [No tests found in this file]

I have been using VScode to Code Spring Boot for the past few weeks, before that I was running the test normally but now I can't find a way to run the test anymore?

I tried to create a new project but still no run test Button to click

Hi Ha Tung (@Hatung69), 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.

Suggestions to restore the Run Test icon and discover your Spring Boot tests:

• Ensure the Java Test Runner extension is active
– Run Developer: Show Running Extensions and look for vscjava.vscode-java-test. If it’s greyed-out or not running, completely uninstall (delete its folder under ~/.vscode/extensions/vscjava.vscode-java-test-*) and reinstall.
Reference: microsoft/vscode-java-pack#948 (microsoft/vscode-java-pack#948 (comment))

• Enable Java Tests in the Testing view
– Open the TESTING sidebar. If you see “No tests have been found in this workspace yet,” click Enable Java Tests and reload.
Reference: #1498 (#1498)

• Verify project layout and dependencies
– Test classes must live under src/test/java.
– Make sure your pom.xml includes the JUnit 5 engine (e.g., via spring-boot-starter-test).

• Restart the Java language server and check logs
– Command Java: Restart Language Server, then open the Java Test Runner output channel for any errors.

Other references with low confidence

• microsoft/vscode-java#2297 – tests not discovered when testSourceDirectory isn’t set to src/test/java; ensures correct Maven layout (redhat-developer/vscode-java#2297)

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 have the same problem. I updated Visual Studio Code and reinstalled the extensions. When I start it, I get the following message in the output window:

HI
I have kinda same issue and copilot said:
In short, the reason is found: JDT Language Server does not load Test Runner / Jacoco bundles because you have a version conflict with the ASM library. The log shows:

org.jacoco.core (in Test Runner) requires org.objectweb.asm ver "[9.8.0,9.9.0)"
from the Red Hat extension redhat.java is set to asm 9.9.0 - 9.9.0 is no longer in the range (the upper limit is excluded), so Jacoco does not resolve → JDT LS crashes → tests are not detected in VS Code.

I switched back to 1.46.0 for Red Hat and now i have a buttons but it's not working properly anyway i'm trying to figure it out T.T
UPD: Yes it works with 1.46.0 fine i'm just dumb.

Thanks Akiko-QA, the workaround works.

It looks like this is similar to this issue,
#1802

Thank you, guys. So this problem is Red Hat version conflict. Try to update the extension
