Software testing principles

Machines are dominating the world of technology and it’s the software which controls the behavior of these machines. Software testing offers the prerequisite solution to the different problems in which the machines behave. As you learn about the principles of software testing, you will get a deep knowledge about the importance of software testing.

Software testing contributes to being the process in which a software product is verified and validated. Through software testing, you can test if the specific software testing can accomplish different technical and business needs which guide the development and design. The success rate of the software application offers a helping hand in controlling business growth. Software testing services plays a crucial role in developing different software products and applications.

Principles of software testing

Software testing is conducted to achieve optimum efficiency while making the process efficient and minimizing cost and saving time.

In this article, we look at the seven basic principles in the software testing.

Software testing reveals defects and bugs

It is necessary to perform software testing properly before the launch of a product or application. The product needs to pass through various phases such as user acceptance testing, system integration testing, beta testing. Different defects which are present in the product will be revealed through software testing.

After the process of software testing, the tester will find if the product has accomplished different needs of the business. In the software testing sector, the testers will never say that the software is completely free from all the defects.

 It is completely true as through testing; it is not possible to prove that the software is free from defects and errors. The objective of testing is finding different hidden defects through various methods and techniques. Software testing helps in finding various undiscovered defects.

Can you perform exhaustive testing?

It is not feasible to perform the testing of different functionalities with the aid of invalid and valid input data combinations during real testing. Hence, it is necessary to conduct the testing with few combinations through various techniques. Through exhaustive testing, limitless efforts are necessary. Majority of such efforts are not effective.

In addition to this, the project timeline may not provide the opportunity to test with such an excessive number of combinations. So, another primary principle of software testing is that it is not feasible to conduct testing of different combinations for every input type.

Early testing

It is a prerequisite to conduct early testing in the earlier phase of Software Development Life Cycle (SDLC). Hence, you should make sure to identify the defects, present during documentation defects and requirement analysis phase. As you go for early testing of the software, the costs which are involved in resolving these errors defects are lesser than in the later phase of testing.

Defect clustering

While performing software testing, it is noticed that most of the defects present in the software are in a smaller number of the modules. Several reasons might be responsible for this. It is referred to as the Pareto Principle of Software testing, in which it is possible to find 80 per cent of the errors, involved in 20 per cent of the modules.

Fallacy - the absence of errors

You will be surprised to know that the software, which is 99 per cent free from errors, might not be suitable for use. Such conditions occur once the tester performs the testing of the software for the wrong requirements.

Software testing is not only about finding the errors and defects in the system. Instead, it is also about checking and ensuring that the software, which is developed during the software testing process, accomplishes the needs of the business. The absence of error is regarded as a fallacy. Fixing and finding the defects is not useful if the built system is unusable and fails to fulfill the requirements of the user.

Pesticide Paradox

In case the same type of tests is performed timely, and again, the test cases will be no more useful in detecting the new bugs. For overcoming this problem referred to as Pesticide Paradox, you should make sure to perform a review of different test cases regularly. You should make sure to write various tests for exercising various parts of the system or software for finding other potential defects.

Software testing is context-dependent

It is worth mentioning the principle of software testing which indicates that there are multiple fields, like commercial websites, eCommerce websites, to name a few. There is a specific way for testing the eCommerce and commercial websites as each application boasts of its functionalities, features and requirements. For checking such kind of application, you should make sure to take the assistance of different types of testing, approaches, techniques, and methods. Hence, software testing relies on the app context.

Software testing is an indispensable part of the SDLC or Software Development Life Cycle. Once it is performed effectively and correctly, it offers amazing results. To complete the right objectives of testing, it is important to implement the maximum testing principles in software development.

It is possible to achieve the same when every member of the team is well versed with the principles of software testing. It is essential to find as many defects as possible before the release of the software. To accomplish this, it is a must for the software testing company, offering QA services to perform testing to find the errors, defects in the software testing.

Summary

If you want to conduct software testing efficiently and effectively, it is essential to gain an understanding of different principles of software testing, as mentioned above. It would help if you keep in mind that they are the pillars of software development. If you want to make the project of software development a grand success, you should make sure to implement the software testing principles, mentioned in this write-up.
