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. Every testing process should be done before testing begins and should be based on the customers requirements. Testing of a software is done by a 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.
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 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 the testing of the complete system on the user’s computer. 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. 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. the software developed is tested whether it meets the requirements and does it please the users and the managers of the organization. The acceptance testing is done by interviewing the users of the software system and the owners or the shareholders of the organization.
Non-functionality testing is done for the performance factor. This can be done by stressing the system, loading work to the system and assessing the outputs that the system provides. Cost is a crucial factor to consider when determining the type of the system and how much it costs to maintain the system. Compatibility testing can be done either during the system testing or during the system installation phase. The above categories should always be used when testing a software system.
