I received a lot of comments on this (especially on reddit) which pointed out some errors....
Dividing an application in N layers is considered a standard and a best practice. It is often thought that this automatically creates a decoupled application. However, just creating layers doesn’t make your code loosely coupled. A typical N-layer application Let’s take a simple...
In my previous post I explained how you could use “Extract Interface” and “ Subclass and override” as effective techniques for breaking dependencies and get existing code under test. In some situations there are other methods either more appropriate or easier to implement. Simplify Parameters When...
When you first start writing unit tests, you probably already have quite a large working codebase. Now, how can you start writing tests for this code? Usually this code isn’t written with testing in mind and it’s probably very hard to test. Your...
In order for our unit tests to become effective we need to lay out some ground rules. What is a good unit test and what can we do to make sure we create tests that actually help us in our development efforts? Because it’s...
