To explain the difference between Black Box Testing and White Box Testing, simply put, if you think about a car, you have two types of people, the driver (black box) and the mechanic (white box). The driver doesn’t really need to understand how the engine works to drive, just press a few buttons and levers and turn the wheel and you are off. The mechanic however, lifts the hood and tinkers with the engines to make the car go, looking at the internal mechanisms, following the flow of petrol into the engine right through to the output gases from the exhaust.
So, what is the best software testing technique for my project? Hmmm, tricky one to answer without looking more closely at your project. There are many factors that determine the software testing techniques you’ll need to employ.
