test_panic

Utility for test cases with panic.

The author of this crate is not good at English.
Forgive me if the document is hard to read.

What is this?

Provides functions for test with panic. For the same purpose, the shoud_panic attribute is provided in the Rust standard, but it is not so useful, hence we created this crate.

Examples

Example with this crate.

```rust

[test]

fn test() { let result = test_panic(|| panic!("message."));

assert!(result.is_panic());
assert_eq!(result.message(), "message.");

} ```

Example with should_panic.

```rust

[test]

[should_panic(expected = "message.")]

fn test() { // Suppresses standard error output. panic::sethook(Box::new(|| {}));

panic!("message.");

} ```
