Software testing is the most crucial in website or software development process. The main aim of testing is to find faults and errors in the software. 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. Software testing can be categorized in the below methods.
Unit testing is a method that tests only a particular set of codes or a specific basic program for the software. The basic faults are now recognized like the syntax and logic errors the testing can be structural where one identifies the code errors or the functionality where the results faults are identified. 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 crucial since a recurring error can lead to unidentifiable errors in the integration stage.
Integration testing is the next category of testing since the tested units are grouped together to perform a particular function. 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. System testing is the testing of the complete system on the user’s computer. The system testing deals with the functionality of the system.
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. the software developed is tested whether it meets the requirements and does it please the users and the managers of the organization. Managers should give reviews about the new software installed in their systems and ask for support where the are unable to understand.
Non-functionality testing can be done to ensure that the software performs as required. Loading jobs on the computer and processing them with the software is one of the ways of checking whether the performance meets the users requirements. Cost is a crucial factor to consider when determining the type of the system and how much it costs to maintain the system. 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.
