Hands-On Microservices with Rust

Testing the crate

That's all, and now we have a crate that can be used to interact with a database. Since it's not binary, we need to guarantee that the code works correctly. It's a good practice to cover your code with tests, and we will do that now.

Add the following code to the lib.rs file:

#[cfg(test)]mod tests {    use super::Api;    #[test]    fn create_users() {        let api = Api::connect().unwrap();        let user_1 = api.register_user("[e-mail]").unwrap();        let user_2 = api.register_user("[e-mail]").unwrap();        let channel = api.create_channel(user_1.id, "My Channel", false).unwrap();        api.publish_channel(channel.id).unwrap();        api.add_member(channel.id, user_2.id).unwrap(); let message = api.add_message(channel.id, user_1.id, "Welcome!").unwrap(); ...
