I have switched to JUnit4.4 from JUnit3.8. I run my tests using ant, all my tests run successfully but test utility classes fail with "No runnable methods" error. The pattern I am using is to include all classes with name *Test* under test folder.
I understand that the runner can't find any method annotated with @Test attribute. But they don't contain such annotation because these classes are not tests. Surprisingly when running these tests in eclipse, it doesn't complain about these classes.
In JUnit3.8 it wasn't a problem at all since these utility classes didn't extend TestCase so the runner didn't try to execute them.
I know I can exclude these specific classes in the junit target in ant script. But I don't want to change the build file upon every new utility class I add. I can also rename the classes (but giving good names to classes was always my weakest talent :-) )
Is there any elegant solution for this problem?
Annotate your util classes with @Ignore. This will cause JUnit not to try and run them as tests.
My specific case has the following scenario. Our tests
public class VenueResourceContainerTest extends BaseTixContainerTest
all extend
BaseTixContainerTest
and JUnit was trying to run BaseTixContainerTest. Poor BaseTixContainerTest was just trying to setup the container, setup the client, order some pizza and relax... man.
As mentioned previously, you can annotate the class with
@Ignore
But that caused JUnit to report that test as skipped (as opposed to completely ignored).
Tests run: 4, Failures: 0, Errors: 0, Skipped: 1
That kind of irritated me.
So I made BaseTixContainerTest abstract, and now JUnit truly ignores it.
Tests run: 3, Failures: 0, Errors: 0, Skipped: 0
Assuming you're in control of the pattern used to find test classes, I'd suggest changing it to match *Test
rather than *Test*
. That way TestHelper
won't get matched, but FooTest
will.
To prevent JUnit from instantiating your test base class just make it
public abstract class MyTestBaseClass { ... whatever... }
(@Ignore reports it as ignored which I reserve for temporarily ignored tests.)
