I Love Dependency Injection But .... I've burned myself so many times with dependency injection in the past. It make me nervous when I see a complex software product comprised of multiple projects and dozens of libraries without any comprehensive test that double checks the wiring. As our wiring grows...

Once you catch the automated testing itch you want to write test for everything. But should we use the same strategy for every piece of software? The conclusion that I’ve come to is no. While I’m completely committed to the practice of TDD and aggressive test coverage, I’ve found that...

Overview Spring is an essential part of my technology stack. I can’t imagine providing quality software that doesn’t leverage an IoC container.

Transactions are an essential component in enterprise software development. When your application works properly you rarely think about transactions. However, when things go wrong debugging transactions can be quite challenging. Instead of being reactive we need to proactively test our transactions. When I first got into the software industry I...

One of the primary principles of unit testing is to test a small piece of functionality in isolation. In order to achieve this, mock objects are often necessary. Historically using mocks could be quite painful. After using several mock frameworks, my favorite by far is Mockito. Tutorial In this tutorial...

You can’t ignore the fact that web servers are multithreaded. We can hide as much as we want, but sooner or later you’ll find yourself in the situation where your application works fine during development and testing; but once it hits production you start hearing about “funny” things happening.
