Whenever unit-tests are written, chances are good that the code is not isolated. Many tests run against a given class/interface/function. The design didn’t consider isolating the dependencies of this function, which makes tests slower, larger, less focused, and likely depending on external dependencies (e.g. database access) which decreases the reliability. …

The message passing (MP) paradigm is often seen as a superior alternative to the typical mix of idioms in concurrent (shared-memory, locks) and distributed programming (CORBA/RMI). MP eliminates worries endemic to the shared-memory mindset: lock ordering, failure-coupling, low-level data races and memory models. It simplifies synchronization between data and control …
