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::set_hook(Box::new(|_| {}));
panic!("message.");
}
```
# What's New
v0.3.0
* `must_use` annotations are added at `TestPanicResult`.
v0.2.0
* Some document is polished.
* `TestPanicResult` holds value on cases where no panic occurred.
