Answer 1

After googled some answers. I found there's an issue talked about this case as below: https://github.com/junit-team/junit4/issues/1277 (FilterRequest may hide the real failure cause(exception) of a test) Here're the steps I tried:
1. don't select the testing function alone, while select "Run all the tests in the selected project" option on the Test Tab, when select the Junit project name after click on Run->"Run(Debug) Configuration"
2. You can get the details of the error as follows:

initializationError(com.company.product.api.web.rest.HostControllerTest)
java.lang.Exception: Method testSetDBConfiguration should have no parameters
    at org.junit.runners.model.FrameworkMethod.validatePublicVoidNoArg(FrameworkMethod.java:76)
    at org.junit.runners.ParentRunner.validatePublicVoidNoArgMethods(ParentRunner.java:155)

3.according to the details given by eclipse above, I removed the argument of that function, the initializedError just disappeared.

So this issue rises due to the new added testing function has unnecessary input argument. The incorrect code :

@Test
public void testSetDBConfiguration(String name) throws Exception {

Changed to

@Test
public void testSetDBConfiguration() throws Exception {

I have found the below solution which worked for me.

your Application @SpringBootApplication package name and Test package name should be same .

see if it helps. Happy coding.
