      • matches

        public boolean matches​(java.lang.Object o)
        Description copied from interface: Matcher
        Evaluates the matcher for argument item.

        This method matches against Object, instead of the generic type T. This is because the caller of the Matcher does not know at runtime what the type is (because of type erasure with Java generics). It is down to the implementations to check the correct type.

        Parameters:
        o - the object against which the matcher is evaluated.
        Returns:
        true if item matches, otherwise false.

        public void describeTo​(Description buffer)
        Description copied from interface: SelfDescribing

        Parameters:
        buffer - The description to be built or appended to.
      • isIn

        public static <T> Matcher<T> isIn​(java.util.Collection<T> collection)

      • isIn

        public static <T> Matcher<T> isIn​(T[] elements)

        assertThat("foo", isIn(new String[]{"bar", "foo"}))
        Parameters:
        elements - the array in which matching items must be found
