### Question:
EntityAsserts { public static <T> void assertConfigEquals(Entity entity, ConfigKey<T> configKey, T expected) { assertEquals(entity.getConfig(configKey), expected, "entity=" + entity + "; configKey=" + configKey); }  static void assertAttributeEquals(Entity entity, AttributeSensor<T> attribute, T expected); static void assertConfigEquals(Entity entity, ConfigKey<T> configKey, T expected); static void assertAttributeEqualsEventually(final Entity entity, final AttributeSensor<T> attribute, final T expected); static void assertAttributeEqualsEventually(Map<?,?> flags, final Entity entity, final AttributeSensor<T> attribute, final T expected); static T assertAttributeEventuallyNonNull(final Entity entity, final AttributeSensor<T> attribute); static T assertAttributeEventuallyNonNull(Map<?,?> flags, final Entity entity, final AttributeSensor<T> attribute); static T assertAttributeEventually(final Entity entity, final AttributeSensor<T> attribute, Predicate<? super T> predicate); static T assertAttributeEventually(Map<?,?> flags, final Entity entity, final AttributeSensor<T> attribute, final Predicate<? super T> predicate); static T assertAttribute(final Entity entity, final AttributeSensor<T> attribute, final Predicate<? super T> predicate); static void assertPredicateEventuallyTrue(final T entity, final Predicate<? super T> predicate); static void assertPredicateEventuallyTrue(Map<?,?> flags, final T entity, final Predicate<? super T> predicate); static void assertAttributeEqualsContinually(final Entity entity, final AttributeSensor<T> attribute, final T expected); static void assertAttributeEqualsContinually(Map<?,?> flags, final Entity entity, final AttributeSensor<T> attribute, final T expected); static void assertGroupSizeEqualsEventually(final Group group, int expected); static void assertGroupSizeEqualsEventually(Map<?,?> flags, final Group group, final int expected); static void assertAttributeChangesEventually(final Entity entity, final AttributeSensor<?> attribute); @Beta @SafeVarargs static void assertAttributeContinuallyNotEqualTo(final Entity entity, final AttributeSensor<T> attribute, T... disallowed); @Beta @SafeVarargs static void assertAttributeContinuallyNotEqualTo(final Map<?, ?> flags, final Entity entity, final AttributeSensor<T> attribute, T... disallowed);  }### Answer:
@Test public void shouldAssertConfigEquals() { EntityAsserts.assertConfigEquals(entity, TestEntity.CONF_NAME, "defaultval"); }
@Test(expectedExceptions = AssertionError.class) public void shouldFailToAssertConfigEquals() { EntityAsserts.assertConfigEquals(entity, TestEntity.CONF_NAME, "bogus"); }
