Last week, I’ve re-read “Test Driven Development: By Example” by Kent Beck. I was amazed by the simplicity of his process, consisting of small pragmatic steps. So, I decided to put the process to the test in an unfamiliar domain.

The kata

In this kata, I am going to develop a serverless service in AWS using a Lambda and the API Gateway. I chose this task because, on the one hand, it will contain a fair amount of infrastructure code, which is considered hard to test. On the other hand, because I wanted a task that was more abstract and closer to a business requirement in contrast to a technical requirement like ‘deploy an AWS HTTP API Gateway’.
