Summary
In this chapter, we went through the workflows and components of our application, breaking them down so we could pick the right tools for the right part. We used unit testing so we could inspect several edge cases quickly to see how each function and struct interacted with others.
We also directly inspected our custom structs with unit tests. We then used the actix_web test structs to mock requests to see how the functions that use the structs and process the requests work. However, when we came to the main API views module, we switched to Postman.
This is because our API endpoints were simple. They created, edited, and deleted to-do items. We could directly assess this process by making API calls and inspecting the responses. Out of the box we managed to assess the JSON processing for accepting and returning data. We were also able to assess the querying, writing, and updating of the data in the database with these Postman tests.
Postman enabled us to test a range...
