Testing must be done to ensure that the errors and faults in the software are eliminated. The main aim of testing is to find faults and errors in the software. Testing should start and planned at an early stage and should be based on the client’s requirements. In software testing the process is exercised by a professional software tester. A software tester can use different methods of testing depending on his or her own preference or what the tester is good at. Software testing can be categorized in the below methods.
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. 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.
More on software testing categories is the interface testing. The interface should meet the customers requirements or the agreed requirements. An interface should be as simple as it can be to allow the user to understand and use the system to the optimal and its’ info should be eye catching such that the software developer can easily market his or her skills in software development. Is the software acceptable by the users and managers of an organization? Is the question to be answered in the acceptance testing. Managers should give reviews about the new software installed in their systems and ask for support where the are unable to understand.
Operation testing is for genuinely assure that the system functions as required by the users. This can be done by stressing the system, loading work to the system and assessing the outputs that the system provides. Recovery testing should be done in order to reduce the cost of maintenance of a software and should be done after all testing is done. While installing a software to a computer it should run without any struggles or errors. The above categories should always be used when testing a software system.
