We all struggle to get our heads around testing Serverless Architectures - mainly because they are distributed and, in many cases, asynchronous. We also struggle because, on our journey to Serverless, we have focused on managed services and have forgotten about good Software Architecture. In this talk, I present SOLID Software Architecture ideas and strategies for breaking down your automated tests so that developers can move faster and get going easier and hopefully de-mystify the process of Testing your Serverless Systems.
