  Generates a description of the object. The description may be part of a a description of a larger object of which this is just a component, so it should be worded appropriately.

  参数:

  description - The description to be built or appended to.

• instanceOf

  public static <T> Matcher<T> instanceOf​(Class<?> type)

  Creates a matcher that matches when the examined object is an instance of the specified type, as determined by calling the Class.isInstance(Object) method on that type, passing the the examined object.

  The created matcher assumes no relationship between specified type and the examined object.

  For example:

  assertThat(new Canoe(), instanceOf(Paddlable.class));

• any

  public static <T> Matcher<T> any​(Class<T> type)

  Creates a matcher that matches when the examined object is an instance of the specified type, as determined by calling the Class.isInstance(Object) method on that type, passing the the examined object.

  The created matcher forces a relationship between specified type and the examined object, and should be used when it is necessary to make generics conform, for example in the JMock clause with(any(Thing.class))

  For example:

  assertThat(new Canoe(), instanceOf(Canoe.class));
