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

For me it was a silly mistake. I inadvertently set the test as private instead of public:

@Test
private void thisTestWasCausingProblems() {
...
}

it should have been

@Test
public void thisTestIsOK() {
...
}
