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. Testing should start and planned at an early stage and should be based on the client’s requirements. 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 Below are some points about software testing method categories.
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. 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.
Here is another category of testing where testing is done after grouping the units together for a more sophisticated functionality. 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. The system testing deals with the functionality of the system.
More on software testing categories is the interface testing. 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. 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. Compatibility testing can be done either during the system testing or during the system installation phase. 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.
