We will need this in the next section when we test our API. com" ], "groups": [ "Dev" ] }] } This data will allow us to test all our five functions. We've already covered the RestClientTool of the Enide Studio. We will continue using it as our primary test tool. Referring to the definition table from the last section, let's perform tests for each operation of our service: 1.
The middleware chain is always called in the exact order in which it has been defined, so it is vital for you to know exactly what a specific piece of middleware is doing.

It will reply with static content as a response to each one of them. In addition to this, a log entry will be displayed on the console for each request.
