Software testing is among the important stages of developing a software. Testing is all about identifying faults in a software product. Early planning of the software testing process and testing basing on the user requirements other the client should be done. In software testing the process is exercised by a professional software tester. Now there are different methods of testing depending on the tester he or she can test both the structural and the functional features of a software. View the following testing method categories below.
Unit testing is the basic method of checking errors in a program and the codes in the program. Unit testing being the basic testing of a software is done to identify the syntax and the logic errors in a program and the codes that make the program. This may be done by a single tester or a group of testers to ensure that there is no room for future errors. It is advisable to correct the errors immediately they are identified. The unit testing is the most sensitive among all the software testing methods since errors not identified are passed to the integration testing method.
Here is another category of testing where testing is done after grouping the units together for a more sophisticated functionality. Integration testing errors can originate from poor testing at the unit testing stage or an error that occurs while integrating the various programs. These group of the integrated units should be functionable and should lack errors. This product is tested using results on the users computer while testing a software is called system testing. The functionality of the system is done in their category of software testing methods.
Interface testing is another category of software systems. A tester checks whether the interface is suitable for users or not. The interface projection should be eye catching for users and easy to understand so as to allow easy marketing of a software developers product. Acceptance testing is checking whether the software is appreciated by the users and the owners of the company. Interviews and questionnaires answering are the main methods used to collect data about the acceptance of the software.
Non-functionality testing is done for the performance factor. Adding a lot of work to the software system and checking its performance is one basic way of non-functionality testing. In maintainability testing the recovery of the system is tested and checked by the system tester such that it may reduce the maintainability cost. While installing a software to a computer it should run without any struggles or errors. In conclusion I would advise both people who learn about testing and professional testers to use all the above testing categories when testing a software.
