Any SQA company could select an approach of their own. However, the team should consider some factors before they could use an approach. The quality of the evaluation could be questioned and ineffective when these factors are not considered.
Software Development Life Cycle (SDLC) Methods – The SDLC methods dictate how the application will be developed. Each SDLC have their own set of applications and recommended frameworks for software development. The SQA team should take note of this factor above everything else since this will reflect how they will approach the SDLC as well.
Cost – If the SQA team is given a free range of budget, they could employ some of the most powerful testing tools developed. This will enable faster software development and ensure better checking of the application. But that is not the case; everyone has to live on a budget including the SQA team. They have to look for the ideal tool for proper evaluation at a better price. If nothing comes up, they have to prepare and ensure adjustments to the approach are made so that the expected performance is met.
Expertise – Last but not the least, the SQA team should know their capacity in handling the tools they will be using. Some of the tools are GUI based that it could be easily handled by any SQA however; the most efficient tools are also the most complicated. So the SQA team should know what they could do. Most SQA methods employ specific tools for the methodology to be very efficient.
Analysis and Static Defect Detection – this approach looks for the possible defects of the application by collecting invariants related to their purpose to the application. Invariants are standard information that will execute in the application. Invariants are functions, values and additional information that instruct the application what to do. Using this approach the SQA team should know which invariant might not work. The tools look for the executable functions and invariants to test them for stability.
Prototype Testing and Checking – In this case we do not look for the bad thing about the application but actually the good thing. Negating the reason for checking could work especially when you are building an application wherein user input is very important. By checking the application response the SQA team will know if the application actually works.
Theory Testing – As the saying goes, “get them while they’re young”. Before the application is implemented, the theory and the thought of the developers regarding the application are scrutinized. Checking the usual format of their development plan, the facts presented are compared against previous information. Through this, the information is verifiable and results could be predicted. Regular testing tools are implemented. The only downside of this is the requirement of experience from the SQA team with corresponding documentation.
