Common Patterns in microservices (Event sourcing, Saga and CQRS)

The first part of the lecture will be a dive into common patterns in microservices. We will explore event sourcing, Saga and Command Query Responsibility Segregation (CQRS) and the opportunities that they bring. And at the end of it, we will build a couple of microservices that use these patterns from scratch.

Testing microservices with Groovy and Spock

The second part will explain more about how to simultaneously test microservices and create documentation with Groovy and Spock, and what advantages they give us when testing. We will also cover how we can easily create data-driven tests with Spock.
