Decoupling microservices with Apache Camel and Debezium

The rise of microservices-oriented architecture brought us new development paradigms and mantras about independent development and decoupling. In such a scenario, we have to deal with a situation where we aim for independence, but we still need to react to state changes in different enterprise domains. I'll use a simple and typical example in order to show what we're talking about. Imagine the dev...

New tools for automating end-to-end tests for VS Code extensions

It is a common practice to test software from the user's perspective before releasing it. With this assumption, I have set out on a quest to find a VS Code extension with automated end-to-end tests.

My quest then became fi...
