This chapter was an interesting one, in which you put your coding skills to practice. You were able to learn how to create the routes we defined in Swagger in Chapter 3, Designing RESTful APIs with OpenAPI and Swagger, so that the application matches the specification.
You also learned how to code starting, with tests and how to validate them with mutation tests by using Stryker.
In addition to this you were able to create a new operation to retrieve orders and apply filter and pagination strategies to that.
The next chapter, Chapter 7, Formatting the API – Output, will walk you through how to format the service output, because having a standard data format for responses is one of the key points of web service stability.
