7 Principles of Software Testing

Exhaustive Testing is not possible:

As a result, rather than carrying out extensive testing, which necessitates endless calculations and results in failure for the majority of the effort, Because the product timelines prevent us from carrying out such testing scenarios, we are able to complete these variations based on the importance of the modules.

Early Testing:

In this context, “early testing” refers to all testing activities that should begin in the “requirement analysis stage” of the software development life cycle in order to find defects. This is because if we find bugs early enough, they can be fixed right away, which may save us a lot of money over bugs that are found later in the testing process.

We will need the documents for the requirement specification in order to carry out testing; Therefore, rather than addressing the issue at a later stage, such as the development phase, if the requirements are incorrectly defined, they can be addressed immediately.

Defect clustering:

During the testing process, we can identify the number of bugs that are correlated to a small number of modules using defect clustering. This is due to a number of factors, including the modules’ potential complexity; The coding might be hard, and so on.

The Pareto Principle, states that we are able to identify that approximately, will apply to these kinds of software or applications. Twenty percent of the modules contain eighty percent of the complications. We can find the uncertain modules with this, but if the same tests are running on a regular basis, this method can be difficult, and the same test won’t be able to find new defects.

Pesticide paradox:

This principle stated that the software or application will not be able to detect new bugs if the same set of test cases is run repeatedly over a predetermined period of time. It is critical to frequently review all test cases in order to overcome these pesticide paradoxes. Additionally, new and distinct tests must be written for the implementation of multiple software or application components to aid in the discovery of additional bugs.

Testing is context-dependent:

According to the context-dependent principle of testing, there are a variety of market sectors, including commercial websites, e-commerce websites, and so forth. Because each application has its own requirements, features, and functionality, there is a certain method for testing commercial and e-commerce websites. To check this sort of use, we will take the assistance of different sorts of testing, different procedure approaches, and various strategies. As a result, the application’s context determines the testing.

Absence of errors fallacy:

We can say that the application is 99 percent bug-free once it has been tested thoroughly and no bugs have been found before it is released. However, there is a possibility that if the application is tested alongside the incorrect requirements, flaws will be discovered, and they will need to be fixed within a certain time frame. This is because the testing is done on the incorrect specification, which does not correspond to the client’s requirements. According to the absence of error fallacy, if the application is impractical and unable to fulfill the requirements and needs of the client, then identifying and fixing bugs would not be helpful.
