    Testing is a vital aspect of the software development process. Most software developers should already know this, but if you find yourself working with people who disagree, it might be time to step back and take stock of the situation. Being familiar with common terminology is a good first step (if this topic is new to you, I advise you to read that article), but decisions about the details of testing implementation can often get tricky. The first among these decisions is deciding when it’s necessary to test. Is it Time to Test? For developers, this question has a simple answer: Yes. If you are coding, you should be testing.
