Running pytest with cargo test

In a project which contains a subcrate which creates python modules with PyO3, many tests are most naturally expressed in a python testing framework such as pytest. Is it possible to get cargo test to execute these, and at least include their status in a single overall pass/fail status, or better still, some pass/fail statistics?

If you are interested in running an external command as part of test, you can do it like this:

mod tests {

    fn pytest() {
        let o = std::process::Command::new("pytest").output().unwrap();
        println!("stdout: {:?}", o.stdout);
        println!("stderr: {:?}", o.stderr);
