@Test annotations ignored, how to get testcase to use Junit 4 ? [message #33351]

I am extending SWTAbstractTestCase, and I specify org.junit4 (4.3.1) in
the dependencies section of the manifest associated with that plugin. But
it only executes the tests if I have "test" in the beginning of the method
name. I do specify Junit 4 as the test runner in Run Configurations. I
then monitor the testcase in the Junit view, (which says "Runner: Junit 4"
if I hover over the tab), but still it only executes the testcases that
say "test" in it (which I understand is a Junit 3 thing right?)... All my
testcases marked with the @Test annotation are ignored. And if I don't
have any methods with "test" in the beginning, then it displays the
following exception:

Any idea why it doesn't seem to be picking up Junit 4? Thanks a lot!

I recommend you not to subclass any SWTBot super class for your JUnit
tests if you want to use JUnit 4.x. To my knowledge the JUnit superclasses
of SWTBot are only intended for JUnit 3.

I write SWTBot JUnit 4 tests this way:

@RunWith(SWTBotJunit4ClassRunner.class)
public class MyTest {
@Test
public void checkSomething() {
// ...
}

A suite can be written like this:

@RunWith(Suite.class)
@SuiteClasses({MyTest.class})
public class MySuite {
}

The annotation "@RunWith(SWTBotJunit4ClassRunner.class)" is needed for the
screenshot-on-failure/error feature of SWTBot.

I hope this helps.
