Software Testing Fundamentals

Software Testing is vital for any software development life cycle, it is fundamental to ensure the software quality and to have a workable functional software at the end of the project.

“Testing is any activity aimed at evaluating an attribute or capability of a program or system and determining that it meets its required results” Bill Hetzel, 1988

The main motive for the testing is to ensure that all functionalities are working correctly as per the requirements. It is not only that this is the basic purpose of testing, while It is important to test how to break the system, how to simulate the abuse of the system by the quality team before someone else does that for you and it will be a disaster at this time.

Black Box Security Analysis and Test Techniques

Black box techniques are the only techniques available for analyzing and testing non-developmental binary executable without first decompiling or disassembling them. Black box tests are not limited in utility to COTS and other executable packages: they are equally valuable for testing compiled custom developed and open source code, enabling the tester to observe the software’s actual behaviors during execution and compare them with behaviors that could only be speculated upon based on extrapolation from indicators in the source code. Black box testing also allows for examination of the software’s interactions with external entities (environment, users, attackers)—a type of examination that is impossible in white box analyses and tests. One exception is the detection of malicious code. On the other hand, because black box testing can only observe the software as it runs and “from the outside in,” it also provides an incomplete picture. Read more
