Every process needs to be optimized if one wants the best output from the given investment. So is the case with Software Testing as well. Usually, it is a complex and resource-intensive process, so it needs to be optimized to get the best output. Testing the software helps to evaluate the functionality of the software to check if there are any errors or bugs. Software Testing helps to check the software on the parameters below:
a) If the software fulfills all the requirements
b) If it meets the technical as well as business requirements as per which it was developed
c)If it can be launched successfully with the same features

ADVANTAGES OF CONDUCTING SOFTWARE TESTING:
In today’s world, the growth of any business is directly proportional to the success of its app. Hence, there is a need for Software testing for the below-mentioned reasons:
- To ensure security
Software Testing helps to sort out the problems or any type of risks if existing, then they can be resolved beforehand.
If the bugs are identified and resolved at the earlier stages of testing, then it is comparatively cheaper to fix them rather than fixing them at the advanced stage.
- Customer is happy
The aim of developing the software is that the maximum number of users use the app. So, testing helps to identify what kind of user-experience the software is enabled to offer to its audience.
- Quality of the product
Software testing enables the developer to ensure that he is on the right path in developing the features.
PRINCIPLES OF SOFTWARE TESTING:
Let’s look into the basic seven principles of Software Testing services USA, which helps to make the testing process effective overall.
- Testing reflects the presence of defects
Testing is all about highlighting the defects of the software. If the QA team mentions that there is no defect at all in the software, do not rely on them. As this means that the QA team is not capable enough of detecting the bugs and errors in the software at such an early stage. So, one should never assume that their software is completely bug-free.
Even if the testing is conducted multiple times, the software cannot be made 100% bug-free. But testing every time can reduce the number of defects in the software.
- Exhaustive testing is not possible at all
Exhaustive testing basically refers to conducting the testing because of all possible combinations of input that a customer can give. And it is not possible to conduct exhaustive testing to conduct each feature and functionality. Even the timeline of the project also does not allow us to conduct the exhaustive training.
Testing to be done after assessing the possible risk factors of the application. One can use the black-box or white-box testing strategies which will optimize the overall testing process.
- Testing early to save time as well as money
It is always suggested to test the software at early stages only. As if any defect is detected at an early stage, then it can be resolved at a low cost. So, if one is looking for better performance, then one can plan to conduct the software testing at an initial stage of analyzing the requirement of the software.
Testing should be done on requirement documents, specifications, and any other sort of document so that if requirements are improperly described, they may be corrected right away rather than waiting until the development phase.
- Defect Clustering
This principle of software testing follows the Pareto principle in which 80% of the defects in software come from just the 20% of modules. It is also observed that 80% of the end users use just 20% of the features of the module.
Most of the problems discovered during testing are connected to a small number of modules. There could be several causes for this, including the complexity of the modules, the coding associated with such modules, and so on.
- Pesticide Paradox
This principle states that if you are testing the same modules again and again then you will not be able to detect the other defects in the software. OS, do not keep on repeating the same tests again and again but in fact, keep on testing new modules.
Thus, in order to overcome the Pesticide paradox, one should keep on trying the new test modules and test cases. And keep on adding and updating the same in order to find more and more defects.
- Testing is completely context-dependent
Different types of software require various levels of testing. The testing of an e-commerce site, for example, differs from the testing of an Android application. The software that has been produced is not all the same. Depending on the type of application, you may utilize a different approach, methodology, techniques, and types of testing.
So, perform the testing as per the related context or else you would not be able to find out the exact defect in the application.
- Be vigilant on Absence of error-Fallacy
Now this principle explains that if the software is found to be bug and defects free to 98-99%, even then it cannot be said that it is the best software. As the software can only be considered as best if the features and functionalities of the software match the ultimate goals of the business.
The software might be defective free but it is all made on the wrong requirements, so it is considered a failure of the software as it doesn’t match the set needs of the business.
The above-mentioned principles clearly state the way of conducting the successful testing of the software. If the above points are followed religiously then it makes the overall testing process more effective, less costly and helps to produce optimized results.
