White-box testing principles
From a software architecture perspective, one of the most important steps of testing is at the time the software is developed. The behavior or functionality of a software, which is apparent only to its end users, is an artifact of the implementation details of the software.
Hence, it follows that a system that is tested early and tested often has a higher likelihood to produce a testable and robust system, which provides the required functionality to the end user in a satisfactory manner.
The best way, therefore, to start implementing testing principles is right from the source, that is, where the software is written, and by the developers. Since the source code is visible to the developer, this testing is often called white-box testing.
So, how do we make sure that we can follow the correct testing principles, and perform due diligence while the software is getting developed? Let's take a look at the different types of testing that are involved during the...
