    • Method Detail

      • isPresent

        public void isPresent()
        Fails if the Optional<T> is empty or the subject is null.
      • isEmpty

        public void isEmpty()
        Fails if the Optional<T> is present or the subject is null.
      • hasValue

        public void hasValue​(java.lang.Object expected)
        Fails if the Optional<T> does not have the given value or the subject is null.

        To make more complex assertions on the optional's value split your assertion in two:

        
         assertThat(myOptional).isPresent();
         assertThat(myOptional.get()).contains("foo");
