Eclipse JUnit - possible causes of seeing “initializationError” in Eclipse window

Question

I know this question is pretty general but I haven\'t found any hints on why this error may show up. What are possible causes of seeing initalizationError in Eclips

Answer 1

In my case, I had the following import in my test case:

import org.junit.jupiter.api.Test;

The correct import is:

import org.junit.Test;

Don't just import any old Test type from junit, make sure you pick the correct one.
