What’s In the Black Box?

BBT

BBT

As you could have guessed from the name Black box Testing is thinking of the system as of a black box. This approach means that the tester is not using precise knowledge of the code’s internal structure. It is all about focusing on the system as on something whole, complete. BBT is also often confused with behavioral testing. They are indeed very much alike with one slight difference. Behavioral testing does not encourage testers with knowledge of internal structure, yet it is not as strict as BBT in forbidding it.

And, as we all know each method has its own pros and minuses. Majority of apps is being tested with various methods due to the fact that there’s no ultimate bug-finding thing that would work with 100% accuracy. So where can we find BBT? On Unit, System, Integration, Acceptance and Regression testing stages.

Tools from the box

Testers mostly use all sorts of recording and back-playing tools while performing BBT. They usually record scripts in Java, Perl, VB or TSL. The tools are mostly used for regression testing in order to find out if the new build code caused any bugs in the previous and properly functioning parts. I won’t be mentioning all names and brands of tools because lots of good ones are open source and easy to find.
