Code (WIP)

#[test]
    fn test_run_server() {
        let addr = "localhost:8080";
        let server = thread::spawn(move || run_server(addr.to_string())); //commenting this line removes the error
        let mut stream = TcpStream::connect(addr).expect("Failed to connect to server");
        let mut reader = BufReader::new(stream.try_clone().unwrap());
        stream.write_all("[Request Translate ATGCGTTGA]\n".as_bytes()).expect("Failed to send request");
        stream.flush().expect("Failed to flush stream");
        let mut buffer = String::new();
        reader.read_line(&mut buffer).expect("Failed to read response");
        assert_eq!(buffer, "[Response Translate MetGlySTO true]\n");
    }

The error is caused when I do cargo test. Removing the snippet above removes the error. This snippet is found at path src/server/mod.rs in mod crate::server::tests lines 53 to 63. Commenting the 3rd line also removes the error
