The quality of software depends on how that software works and the way it provides services. And quality software is defined as the software which is error free and fulfills the requirements and desires of the client in the most efficient way.
The software testing affects the quality of that software intensely. Since a software passes through various levels in an IT industry, it is tested by a software developer, a software tester, the project manager and then, at last, the client.
The software coding is checked out, filtered out, and is updated several times during the execution of the software that is developed. Each time the code is updated, the errors or bugs are removed and thus the quality of software increases.
Since the developer develops the software, the software tester checks the software for any error or bug and also observes its proper working. After the complete verification and validation of the software, the tester forwards the software to the project manager.
The manager then checks the software again, uses it, runs it, and checks that whether the software is fulfilling the desired requirements of the client in an appropriate way or not.
When the checking of the software from the manager side is done and he is satisfied with the working and the perfection of the software it is labeled as quality software.
The software tester performs the software testing in various ways to detect every possibility of encountering an error. Each time, a bug or an error is encountered or the software does not meet the expectations, the coding of the software is altered or edited.
Although the Selenium Automation is growing at a faster pace but software Testing is still in use.
These small changes or alterations in the coding help the software to perform better. The different ways in which the testing is carried out, are given as follows:
- Unit Testing: The main objective of unit testing is to validate every distinct unit of the app as it is designed. In an application, a unit is basically the smallest part, of which there are one or more input and one output. This testing is generally done by the developer himself.
- Black Box Testing: Typically, when the software is finished developing, the testers execute this software testing method to ensure that the application is working as per specifications.
- White Box Testing: It is an application's internal code and infrastructure testing. It focuses on consolidating security, improving design and usability, and through the application, on the flow of input and output.
- System Testing: It is the process of checking an integrated software and hardware so that it can verify that whether the system meets its specified requirements or not.
- Regression Testing: It is one of the software testing methods to verify that the application which was developed and tested previously is still performing properly after interfacing with other software.
This method is mainly used to ensure that the alterations such as feature enhancements or configuration updating may not have introduced any new mistakes.Along with these, there are some other methods also to test software. When software passes through these testing methods, every time the errors are removed which leads to an increase in the quality of the software.
