Hands-On Microservices with Rust

Implementing tests

With the utilities we've created so far in this chapter, the unit tests look pretty compact. To test the handler of the /signup path that expects UserForm, we will add a test_signup_with_client function with the #[test] attribute:

#[test]fn test_signup_with_client() {    let user = UserForm {        email: "[e-mail]".into(),        password: "abc".into(),    };    test_post("/signup", &user);}

When we run the cargo test command, this function will be called and the test_post call, in turn, will bootstrap a server with a mock server as well.

To test a handler of the /signin path, we will use the following function:

#[test]fn test_signin_with_client() {    let user = UserForm {        email: "[e-mail]".into(),        password: "abc".into(),    }; test_post("/signin", ...
