In the previous article of the series, we have explored the problems of testing a monolithic component and how said problems can be mitigated. This time let's take on another issue that often stands in the way of testing: maintaining a state. As far...

Object-oriented programming is all about recreating real-life objects and patterns of their interaction in code. However, since most of the concepts we deal with in our daily programming routine in fact have little to no physical representation (JSONParser...

One can often hear that "well-designed software is easy to test". Truth be told, testability is rarely just a lucky side-effect of good design, but a competent architect will keep testability in mind when planning for any sufficiently large or important...

The doctrine of object-oriented programming dictates that exceptions are the mechanism of choice to raise (and, possibly, handle) severe error conditions that cannot be safely ignored by the client code. Let me just take a step back to explain why I think...

Designing an efficient interface that decouples a component from its client is a fairly routine task that's easy to mess up. A component is supposed to be highly reusable, flexible and easy to use, not to mention well isolated. Satisfying these diverse...

Each programmer has their own way of thinking. Some of us churn out countless lines of code per day by concentrating on what they are trying to achieve rather than how exactly they are doing it. Others, often regarded as slower thinkers, tend to ponder...
