BDT – Automating Your Application Testing in Behavior-Driven Way

Quote: “Descriptive style takes its roots from the «chain» pattern, in which the methods enclosed in classes return some reference on themselves.”
Another Quote: “Business-driven testing or BDT allows non-technical members of any development team a stronger involvement in the development process by allowing them to comprehend test cases and even create their own. “

Determinism: Requirements vs Features

Abstract: Apparently, in practice there is big difference between cross-platform determinism and same-executable determinism, both in abilities they can provide, and from implementation complexity point of view
Quote: “Cross-platform determinism is the strictest definition of determinism I know; not surprisingly, there are quite a few factors which can break it”

Deterministic Components for Distributed Systems

Quote: “Then you can recover from any single server failure in a perfectly transparent manner”
Another Quote: “after the program fails in production, we can get the input log and run it in the comfort of a developer’s machine, under a debugger, as many times as we want, and get exactly the same variables at exactly the same points as happened in production”

Network Programming: Socket Peculiarities, Threads, and Testing

Quote: “I am not saying that this architecture is the only viable one, but it does work for TCP for sure (and performs reasonably well too)”
Another Quote: “The whole task of optimizing performance beyond, say, 20-50K packets/second per box tends to be Quite Elaborated, and involves quite a few things which are platform- and hardware-dependent.”

Avoiding ugly afterthoughts. Part b. Coding for Security, Coding for i18n, Testing as a Part of Development

Quote: “Doing sanitization at IDL level automates quite a bit of tedious-and-error-prone work, which is always a Good Thing™”
Another Quote: “Hey, this whole thing can be made MUCH simpler, the only thing we need to acknowledge is that the best identifier for a string is the string itself!”
