+ * your filter to the {@link org.junit.runner.Request} before running it (see 
+ * {@link org.junit.runner.JUnitCore#run(Request)}. Alternatively, apply a <code>Filter</code> to 
+ * a {@link org.junit.runner.Runner} before running tests (for example, in conjunction with 
+ * {@link org.junit.runner.RunWith}.
