/**
 * Indicates that this test can fail randomly.
 * <p>When used on a method in a class extending {@link NbTestCase},
 * the implicit suite will exclude this test in case the system property
 * <code>ignore.random.failures</code> is set to <code>true</code>.
 * When used on a class passed to {@link NbTestSuite#NbTestSuite(Class)} or {@link NbTestSuite#addTestSuite(Class)},
 * the suite will be empty if the system property is set;
 * the same if it is used on a class extending {@link NbTestCase}.
 * <p>Test runs which must be reliable should define the system property.
 * (E.g. for NetBeans modules: <code>ant -Dtest-unit-sys-prop.ignore.random.failures=true test</code>)
 * Developers running tests interactively should not.
 * @since 1.51
