How to get Junit 4 to ignore a Base Test Class?

Use to @Ignore annotation. It also works on classes.
See this one:

@Ignore public class IgnoreMe {
                        @Test public void test1() { ... }
                        @Test public void test2() { ... }
                }

Also, you can annotate a class
containing test methods with @Ignore
and none of the containing tests will
be executed.
