Introduction. As a product is being developed and maintained its test suite is enriched as features and functionalities are added and enhanced. Ideally, development teams should aim having a lot of quick unit tests that are run whenever modifications in the code are made. It is great if these are written before or at least together with the tested code, cover as many use cases as possible and finish running after a reasonable amount of time. MORE

It's no secret code is a complicated thing to write, debug, and maintain which is necessary for high software quality. Moreover, high code complexity brings with it a higher level of code defects, making the code costlier to maintain. So, by reducing code complexity, we can reduce the number of bugs and defects, along with its lifetime cost. What exactly is complex code? How can we objectively assess how complex a piece of code is, whether that's an entire codebase or one small function? MORE
Ah yes—“It works fine on my machine!” Perhaps the most famous saying in our industry. Even with the advent of containers that provide consistent environments across the SDLC, we still hear developers fall back to this claim when a defect is found. But in the end, if the code doesn't work in test or production, it doesn't work—even if it works locally. MORE
It's a strange time. We work from home. Political messages have invaded our social media. Layoffs over here, bailouts over there. Yet many of us still spend most of our days in front of a screen, writing software and helping improve it. MORE
