The most surprising thing to me about DDD is how bounded contexts (BCs) is a linguistic boundary, and how we talk about things is dependent on where we are in the system. It feels very human, which intrigues me greatly. To craft a metaphor; the software system is a like Europe and each BC is a country like Spain, France, Italy, and Germany. Each country can be said to have its own culture and language. During trade or tourism, the countries interface in a more limited common language/interaction. But when in Rome, do as the Romans do. The most thrilling thing for me is seeing how one tests in hexagonal architectures. I am attracted to testing and I really love seeing how folks approach testing. The core (domain) remains the same, but observable side effects come from what you plug in. Want to send an email given some scenario? Plug in the production code. Want to test it? Plug in a module to create test assertions.
