software testing principles

Testing contributes to being the indispensable part of software development. Structuring it can be a complicated process.

However, if you accomplish it, you can reap a lot of benefits. Owing to these complications, it is recommended to review different guidelines and processes, thereby assuring that you adhere to the best industry practices.

Software testing is recognized as the process of implementing the app or software to identify different bugs, errors, and defects. If you are planning to perform software testing, it is necessary to follow certain principles to make the specific product free from all kinds of defects.

It is also useful to the test engineers in testing the specific product in due course of time. As you read this article, you can seek information about the seven principles of software testing:

Testing reveals the presence of the errors, not the absence.

The analysts of QA Companies perform software testing for discovering different kinds of issues, errors and problems. After this, the developers fix the errors before the release of the market in the market.

Performance of software testing allows you to have the prerequisite confidence that every software is working properly.

But, such kind of testing process will not assure that the product is free from all kinds of bugs. Testing plays an integral role in decreasing the total counts of undiscovered defects present in the software.

It will help if you remember that resolving and finding the bugs do not assure that the product is not completely free from errors.

You should ensure that software testing is going to reveal the presence of errors and the absence. It offers a boost in confidence that the product is going to encounter failure. It will help if you consider creating a comprehensive software test strategy inclusive of different test statistics, reports, and plans and different test release plans.

It is not possible to execute exhaustive testing.

It refers to the technique to test the software’s functionality in different possible pre-conditions and inputs, which is referred to as exhaustive testing. Exhaustive testing is known to be impossible, indicating that you can test the product for all the test cases. It is going to test just a few of the test cases, after which it will assume that the specific product is correct.

Finally, it is going to generate the correct output for different test cases. If the QA analyst goes for testing all the test cases, it will take a lot of effort and time. Besides this, it will involve a huge cut off from the pocket, which is not practical.

Opt for Early Testing

It is essential for software testers to start the testing process during the earlier phase of SDLC or Software Development Life cycle. Hence, you can recognize all the defects during the specific requirement analysis phase. The costs included during the fixing of different defects are minimal, than the defects present during the software testing’s later phases.

After the finalization of the requirements, the software testers involve testing. Therefore, it is recommended to execute software testing on different requirement specifications, documents and different kinds of documents. Then, if the requirements get defined incorrectly, you can fix it in no time, instead of fixing the same during the software development stage.

Pesticide Paradox

As the pesticide’s repetitive use of the similar pesticide can remove the insects during the farming process, it will develop resistance to those pesticides. The same is applicable to software testing. If you continue to execute the similar set of different repetitive tests, the similar technique will not be helpful to discover the defects. If you want to overcome this, you should review and review the test cases regularly. After this, you should add different test cases for finding different defects easily.

The QA analyst is not going to rely on existing software testing strategies. Hence, it is necessary that the software tester should improve different kinds of existing techniques continually for making the software testing very effective. However, even after executing all the hard and sweat hard work during software testing, you cannot be ensured that the software is error-free.

Defect clustering

Defect clustering refers that during the execution of the software testing process, you will be successful in detecting the total number of errors and vulnerabilities, which are interlinked to the smaller count of the modules. There are different reasons behind it, like the modules, which are extremely complex.

 Such kinds of applications and products adopt the Pareto principle, indicating that you will be capable of recognizing the errors. 80% of the complications is going to present in 20% of modules. Through it, you will be successful in detecting the uncertain modules. However, the process encounters difficulties once similar tests get executed regularly. Thus, similar tests will not be capable of recognizing the latest defects.

Software testing is known to be context-dependent

Software testing is known to be context-dependent. It refers to the process in which the testing of the eCommerce sits is different from the process in which you will be besting the shelf application. It will help if you remember that every development product is not similar.

 You should use different techniques, methodologies, approaches, and different kinds of software testing, which depend on the software app type. The POS system at the specific retail store will be different from the testing of the ATM machine.

Absence of vulnerabilities

Once the software is tested completely and no vulnerabilities are present during launching, it can be said that the specific product is 99 per cent free from errors. But, there are risks that the product has been tested against different wrong requirements.

During such cases, finding the errors and fixing them in due course of time is not going to help if the software testing is executed on the wrong requirements, which are no same, according to the requirements of the potential audience.

Implementation of the principles as mentioned above will be useful in keeping you more focused and effective. Furthermore, it plays an integral role in bringing an improvement in the quality of the entire software testing strategy.
