Principles of Software Testing

What Are The 7 Principles of Software Testing?

To achieve success, every individual sets goals and targets. Furthermore, shaping their lives with a set of principles. Similarly, in the world of technology, some machines are controlled by various software. And they need to be complemented by a set of principles to wipe out all hurdles. Moreover, this feat can be achieved with the help of Software Testing. But to get in-depth knowledge of why and how Software Testing is helpful, it is imperative to know about the Software Testing principles.

These software testing principles and practices make the whole process timely and effective. So, let’s see what are the 7 key principles of software testing.

7 Principles of Software Testing Explained

Well, these software testing principles in software testing have been in existence for a very long period. But not every tester is well-versed in its efficiency. Therefore, hereby we are imparting 7 software testing principles basic knowledge for clear understanding.

1. Testing shows the presence of defects

Software testing does find defects in a software program. But testing cannot make or prove that the software is completely defect-free or free from errors. Instead, it will dig deeper to unearth defects using various tools. So, the testing team scans the entire software but might not necessarily find defects. Because, alongside this, testing has other objectives too. First – that whether the software meets all business requirements and second – is it functioning as per the user’s requirement.

2. Exhaustive testing is impossible

If you have extensive input data, then testing every functionality isn’t possible. It goes without saying that some of the crucial combinations must be tested on a priority basis. But owing to the project timeline, some combinations need to be dropped. Additionally, it is important to map the effectiveness of the efforts exerted on specific combinations and flow. Therefore, the team has to come up with a plan to measure which combination needs more attention.

3. Early testing

One of the key software testing principles is early testing. Because it helps in identifying defects at an early stage thus making the whole process cost-friendly. With this, it means that software testing introduced before the development phase is like icing on the cake especially from a financial point of view.

4. Defect clustering

During testing, there is a time when maximum defects are found or related to a small number of modules. The reason behind these defects is abundant like complex coding, or the nature of the module, etc. And in such cases, the Pareto Principle application comes handy wherein the rule of “80:20” is applied. In this scenario, 80% of the problems are found because of the 20% of the modules. Thus, defect clustering utilizes the expertise of the testing team to identify the potent modules that need testing. This saves time and focus is shifted on areas that need attention.

5. Pesticide paradox

There are times when the testing team repeats the same test again and again, but no longer finds new bugs. This process of repeating the same test is called a Pesticide Paradox. Thus, to curtail this scenario, it is imperative to review and revise these test cases. If it becomes difficult to find any more defects then it is advisable to add a new set of test cases and delete the existing test cases.

6. Testing is context-dependent

There is a wide range of domains available in the market. And every domain has its own set of applications. However, for each of these domains, the applications used may have varied functions, requirements, objectives, and vice versa. Therefore, every domain has to be tested differently using a different approach. Thus, software testing relies on the context of that domain or application.

For example, you cannot follow the same software testing techniques for banking and e-commerce applications. They both persist in their own set of challenges that need to be handled differently. Therefore, forcing you to exercise different methods of testing.

7. Absence of error – the fallacy

While coming up with a software, noting down the correct business requirement is immensely important. Although you design 99% defect-free software but incorporate the wrong requirement then the software is inefficient. Whatever software you design, it must comply with predefined business requirements. The objective of testing is to ensure that the requirement is understood and measured during execution.

So, these are the 7 fundamental principles of software testing that one must follow to reap maximum benefits. Don’t use them just to clear exams but try and assimilate the practical knowledge. And if you have doubts, then enroll in a software testing training institute in Pune.
