Software testing is among the important stages of developing a software. 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. Testing of a software is done by a software tester. There are various testing methods depending on the software tester, the testing can be of either structural or functional features of a software View the following testing method categories below.
More on the software testing methods is the unit testing. The syntax and the logical errors in a program and codes are identified in this testing category. The testing can be entrusted to an organization or a single tester. 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.
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. The unit compatibility is done in the integration testing category and correction measure are put to ensure the testing process continues smoothly. System testing is another category that comes behind the integration testing it the testing of whole software system on the client’s computer. The system testing deals with the functionality of the system.
Interface testing is a method that can be used to categorize the basic types of testing. A tester checks whether the interface is suitable for users or not. This interface should always be simple to understand and use and the interface of a software should be attractive and maybe used even to market the software developer. 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 is done for the performance factor. 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. In maintainability testing the recovery of the system is tested and checked by the system tester such that it may reduce the maintainability cost. A software cannot be used on the users computer of this company if it is not compatible to the computer system available, always check the existing systems before developing a software. 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.
