-
hasMessage
Verifies that the message of the actual (@code Throwable) is equal to the given one, after being formatted using theString.format(java.lang.String, java.lang.Object...)
method.Example:
Throwable invalidArgException = new IllegalArgumentException("foo is not a valid input"); Throwable throwable = new Throwable(invalidArgException); // This assertion succeeds: assertThat(throwable).hasMessage("%s is not a valid input", "foo"); // These assertions fail: assertThat(throwable).hasMessage("%s is not a valid input", "bar"); assertThat(throwable).hasMessage("%s is not a valid input", 12); assertThat(null).hasMessage("%s is not a valid input", "foo");
