Unit Testing: Yes, Rest APIs can also be tested using unit tests. This involves executing the HTTP requests and validating the result. Although this method initially requires more effort, it offers the advantage of complete integration into your development process and enables continuous testing. Each programming language has its own tools. I mainly develop with JavaScript, so I can show you a practical example here. I use Mocha and Chai as testing frameworks. For each test, one or more requests are sent to the corresponding Rest API endpoints and the result is validated.

swagger-ui
Swagger UI is a collection of HTML, JavaScript, and CSS assets that dynamically generate beautiful documentation from a Swagger-compliant API.
An API is like a contract between a client and a server or between two applications. Before testing the implementation, it must be ensured that the contract is correct by checking the specification (e.g. Swagger or OpenAPI). For Rest APIs, it is important that all HTTP REST semantics and principles are adhered to. This is all the more important for publicly accessible APIs so that all functionalities can continue to be guaranteed after updates.
