Mastering Testing in a Hexagonal Architecture

I am a big fan of hexagonal architecture. It has simple principles but is powerful for building long-lasting, high-quality applications.

However, this talk is not about this particular architecture. You can find hundreds of resources online. Instead, it focuses on making the most of hexagonal architecture through a comprehensive testing strategy.

In this session, we will discuss:
- The definition of a testing strategy
- Different types of tests, including contract tests
- Identifying the best test type for each component of hexagonal architecture
- How everything fits together to cover every aspect of the application with minimal execution time
- The proper way to measure coverage (hint: mutation testing)

This talk is perfect for people already using hexagonal architecture and looking for a fresh view on how to test their application effectively.
