Allow message specification for should_fail The test harness will make sure that the panic message contains the specified string. This is useful to help make `#[should_fail]` tests a bit less brittle by decreasing the chance that the test isn't "accidentally" passing due to a panic occurring earlier than expected. The behavior is in some ways similar to JUnit's `expected` feature: `@Test(expected=NullPointerException.class)`. Without the message assertion, this test would pass even though it's not actually reaching the intended part of the code: ```rust #[test] #[should_fail(message = "out of bounds")] fn test_oob_array_access() { let idx: uint = from_str("13o").unwrap(); // oops, this will panic [1i32, 2, 3][idx]; } ``` 2014-12-05 07:02:36 +00:00			`// check-stdout`
