The question may appear to be quite a naive one, but I just can't get my head round it.

Is it possible to use junit Categories in SWTBot tests? I have an example test suite (code below) while running it as 'SWTBot test', I get the following error:

The test suite I'm using:

SlowTestSuite.java

interface SlowTests {
}

@RunWith(Categories.class)
@IncludeCategory(SlowTests.class)
@SuiteClasses(A.class)
public class SlowTestSuite {
}

A.java

@RunWith(SWTBotJunit4ClassRunner.class)
public class A {
    
    private static SWTWorkbenchBot bot;
    
    @BeforeClass
    public static void firstBefore() {
        System.out.println("Executing A.firstBefore()");
        bot = new SWTWorkbenchBot();
    }
    
    @Test
    @Category(SlowTests.class)
    public void a() {
        System.out.println("Executing A.a()");
        System.out.println(bot.activeShell().getText());
        Assert.fail();
    }

    @Test
    public void b() {
        System.out.println("Executing A.b()");
    }

    @Test
    public void c() {
        System.out.println("Executing A.c()");
    }
    @AfterClass
    public static void after() {
        System.out.println("Executing A.after()");
    }
}

I tried using @Category annotation on the class level instead of individual method, but no luck. Any help will be much appreciated.

After googling a bit I got referred to this JUnit issue fixed in JUnit 4.13. What version are you using?

https://github.com/junit-team/junit4/issues/751

This was the duplicate issue that linked to it:

https://github.com/junit-team/junit4/issues/761

Let us know if that helps.

Ahh, Thanks for your reply Patrick. I had googled quite a lot about it but it appears I somehow missed this link.

I'm using 4.12 that I suppose is the latest stable build. I'll however try and update to 4.13 to see if that works.

Regards.
