Hands-On Microservices with Rust

Starting a server for testing

We will start a server instance in a separate thread, because Rust runs tests in multiple threads, and we won't create a server instance with a unique port for every test run to show how you can use a shared instance, because integration tests often need to reuse the same application instance. Create a shared flag that we will use to detect routers that have already started:

lazy_static! {    static ref STARTED: Mutex<bool> = Mutex::new(false);}

Now, we will use this Mutex to create a function to start a server. Look at the following setup function implementation:

fn setup() {    let mut started = STARTED.lock().unwrap();    if !*started {        thread::spawn(|| {            let url = mockito::server_url(); let _signup = add_mock("POST", ...
