Crate time_test

time_test is a super simple crate that you can use to easily obtain how long your tests took to run. Using it is simple (see example/ for an example use case):

#[macro_use]
extern crate time_test;

#[cfg(test)]
mod tests {
    #[test]
    fn my_test() {
        time_test!();

        println!("hello world");

        {
            time_test!("sub-assert 1");
            assert!(true);
        }
        assert_eq!(1, 1);
    }
}

Adding the time_test!() macro to the line in your test from which you want to measure the test duration will result in the duration that the test has taken being shown in the test result line:

$ # 1 test thread so that the output is not garbled.
$ cargo test -- --test-threads=1

TestTimer

TestTimer allows to easily time tests. It's recommended to use the time_test!() macro instead of invoking this type directly.
