-/**
- * The {@code DisableOnDebug} Rule allows you to label certain rules to be
- * disabled when debugging.
- * <p>
- * The most illustrative use case is for tests that make use of the
- * {@link Timeout} rule, when ran in debug mode the test may terminate on
- * timeout abruptly during debugging. Developers may disable the timeout, or
- * increase the timeout by making a code change on tests that need debugging and
- * remember revert the change afterwards or rules such as {@link Timeout} that
- * may be disabled during debugging may be wrapped in a {@code DisableOnDebug}.
- * <p>
- * The important benefit of this feature is that you can disable such rules
- * without any making any modifications to your test class to remove them during
- * debugging.
- * <p>
- * This does nothing to tackle timeouts or time sensitive code under test when
- * debugging and may make this less useful in such circumstances.
- * <p>
- * Example usage:
- * 
- * <pre>
- * public static class DisableTimeoutOnDebugSampleTest {
- * 
- *     &#064;Rule
- *     public TestRule timeout = new DisableOnDebug(new Timeout(20));
- * 
- *     &#064;Test
- *     public void myTest() {
- *         int i = 0;
- *         assertEquals(0, i); // suppose you had a break point here to inspect i
- *     }
- * }
- * </pre>
- * 
- * @since 4.12
