The #[should_panic(expected = "...")] attribute is used in Rust to test whether a specific function successfully panics under certain conditions. The attribute takes an optional parameter expected
that specifies the string that is expected to cause the panic. To make the attribute match, the following steps should be followed:
The function being tested should contain the code that is expected to panic.
The attribute should be added to the test function, with the expected
parameter set to the string that is expected to cause the panic.
The entire test function should be wrapped in a #[test]
attribute.
The test function should be run using a test runner, such as cargo test
.
If the function being tested panics with the expected string, the test will pass. Otherwise, the test will fail.
