How to simultaneously run all JUnit tests for a Eclipse Java project without Maven?

Question

I have a small Java project in Eclipse. I have a class of JUnit tests for each class in the project. I'm using JUnit 4, and this is not a maven project.

Is there an easy way to tell Eclipse to run all tests in all test classes at once?

Answer 1

Select the source directory containing all test classes, right-click, select "Run as..." and select JUnit test.

Answer 2

Right click on a source folder then Run As… > JUnit Test.
