JUnit's error "No tests found with Test runner JUnit4" and "the input type of the launch configuration does not exist"

"Foreword" uncomfortable ...

Eclipse always error: No tests found with Test runner JUnit4

First, here are a few points

1 Have you imported the JUnit package (which you brought in eclipse) if you used the spring test class to import the Spring-test package

2 Whether your package version is too low

3 have not used @testcase annotation

4 has not inherited TestCase class or related test parent class (as if Spring-test does not need)

5 Quote TestCase?

——————————————————

And then I did it. and reported the input type of the launch configuration does not exist error

Workaround:

If you are are getting the above error message in the Eclipse IDE, while running your test case, just make sure so you have the Test class as a part of the "Eclipse source folder" definition. Easiest way. Right click on the folder–> build Path–>use as source folder is done.

Click on your package right click BuildPath dot use as source folder done.
