fn test_something() {
    testing_logger::setup();
    warn!("Something went wrong with {}", 10);
    testing_logger::validate( |captured_logs| {
        assert_eq!(captured_logs.len(), 1);
        assert_eq!(captured_logs[0].body, "Something went wrong with 10");
        assert_eq!(captured_logs[0].level, Level::Warn);
    });
}
