How to do it...

To explore cargo testing capabilities, follow these steps:

1. Create a new project on the command line with cargo new test-commands --lib and open the resulting folder in VS Code.
2. Next, replace the content in src/lib.rs with the following:

#[cfg(test)]mod tests {    use std::thread::sleep;    use std::time::Duration;    #[test]    fn it_works() {        assert_eq!(2 + 2, 4);    }    #[test]    fn wait_10secs() {        sleep(Duration::from_secs(10));        println!("Waited for 10 seconds");        assert_eq!(2 + 2, 4);    }    #[test]    fn wait_5secs() {        sleep(Duration::from_secs(5));        println!("Waited for 5 seconds");        assert_eq!(2 + 2, 4);    }        #[test]    #[ignore]    fn ignored() {        assert_eq!(2 + 2, 4);    }}

3. As we did in other recipes, we can execute all tests with the cargo test command: ...
