Bartek Kuczyński - Examples, properties, mutations, i.e. unit tests on grazing
Each of us writes unit tests (as the metrics are red). Each of us uses TDD (Hard, We Continue). Everyone would like to somehow simplify this process so as not to waste time on "unimportant things". To achieve this, you should reach deeper into the tool bag. During the lecture, I will talk about different approaches to unit tests. About how to use tools to improve work. And about the fact that TDD is not a perfect solution, but we don't have better yet.
Andrzej Grzesik - Scooby RAM, where are you?
Java, the runtime, likes memory. And it is also a fact well known to those who know it well, that subtle differences in code, result in drastic changes to applications memory and runtime profiles. I'll take you through the memory lane part of my work, and show how do I approach analysis, problems and troubleshooting. Tools, what information can they surface, and how to navigate back to the code. Techniques and libraries, how do they affect what the application does. Feel invited if you believe troubleshooting memory in Java is "magic", or "only tuning the GC can save us".
