Error TestEngine with ID "junit-vintage" failed to discover tests when using Intellij

Question

I'm working on a group project and am trying to run a test. When running it I get the error in the file along with org.junit.platform.commons.util.PreconditionViolationException: Could not load class with name ...

I've tried invalidating caches and restarting and I've also tried re-importing the pom.xml file but I'm still getting the error when trying to run a test.

Any help would be much appreciated.

I'm using intellij IDEA 2019.2.4 (Community Edition)

Error that Intellij is showing

Answer 1

If you don't use 'junit-vintage' is better remove from the springboot dependency... in some version this module is not executing... For me resolved.

see this Question: spring-boot-starter-test with JUnit 5
