Testing must be done to ensure that the errors and faults in the software are eliminated. Recognition of error is basically the function of testing. Early planning of the software testing process and testing basing on the user requirements other the client should be done. The testing process is executed by a person known as a tester or a group of testers. 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.
Unit testing is a method that tests only a particular set of codes or a specific basic program for the software. The syntax and the logical errors in a program and codes are identified in this testing category. The testing can be done by a single tester or a group of testers. More info on unit testing an error can be corrected before moving to the next stage. 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. Errors not identified in the unit testing can be identified in the integration testing. Every unit should compatible to the other and also be able to work together as a group of units. System testing is another category that comes behind the integration testing it the testing of whole software system on the client’s computer. How a software operates is the main test done in the system testing category of methods of software testing.
Interface testing is a method that can be used to categorize the basic types of testing. Users are asked on their opinion about the interface of the software and whether they can click the buttons in the interface. 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. Adding a lot of work to the software system and checking its performance is one basic way of non-functionality testing. Cost is a crucial factor to consider when determining the type of the system and how much it costs to maintain the system. 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. The above categories should always be used when testing a software system.
