How to get JUnit tests annotated with @Tag to be executed in suite that has @IncludeTags?

问题

I have the following code:

Test class:

@Tag("foo")
class SomeIT
{

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

}

Suite class:

@RunWith(JUnitPlatform.class)
@IncludeTags({"foo"})
//@SelectPackages("org.foo")
public class SomeITSuite
{
}

My pom.xml:

This executes the suite with 0 tests in both Idea and a console (using mvn clean install -Pintegration-tests).

If I restore the commented out @SelectPackages("org.foo"), it will run all the tests, regardless of whether they're tagged, or not. What am I missing here? Is this a bug?

回答1:

Apparently, when JUnit scans the classes, it doesn't identify such that end with IT as integration tests. I had to rename them to *ITTest and things started working.

If anyone's interested in more details, you can have a look at this pull request.
