Testing is one of the most critical activities in software development and using third-party APIs like DynamoDB in your code comes with challenges when writing tests. Today, I’ll show you how you can start writing tests for code that accesses DynamoDB from Python.
After describing the context of the test pyramid for Infrastructure as Code in part 1, and the Web Application in Part 2a - let`s apply that to some Lambda function.
With CDK you create Infrastructure as Code - IaC. You can automate the test for the IaC code. The three test tastes -Unit, Integration and Application- should work closely together. Here I show you how. It is like the three steps of coffee tasting: 1 smell, 2 Taste, 3 Feel.
TL;DR You don`t need a DSL to do easy integration testing. With CDK available in go, infrastructure test can be programmed with GO packages easily.
Why Go? Go(lang) is a fast strongly typed language, which is a good fit for AWS lambda and other backend purposes. I am going to highlight some nice go features. Usually this leads to heated discussions about the “best” programming language…
