Hands-On Microservices with Rust

Utils

Like we did for unit tests, we'll add some utility function to avoid creating HTTP clients for every test. We will use predefined methods to health-check and to send POST and GET requests to microservices included in the application. Create a utils.rs file and import the necessary types:
