Production is the only environment that truly matters to your organisation, which is why that should be the focus of what we build and how we build it. If we're working in a Microservices world, this is actually something we can do quite effectively by modelling our external connections properly.

In this session, we'll talk about the different feedback loops we get in software and also how we can model an outside-in testing approach for faster feedback and greater confidence.

I'll talk about this from the perspective a system I built over 2 years with almost not class or method level tests.
