Software testing is among the important stages of developing a software. Testing is all about identifying faults in a software product. Testing should start and planned at an early stage and should be based on the client’s 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. Below are some points about software testing method categories.
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. This may be done by a single tester or a group of testers to ensure that there is no room for future errors. It is advisable to correct the errors immediately they are identified. Ensure that all errors are eliminated in the unit testing stage.
Integration testing is a category of testing done after combining the basic software units. Integration testing errors can originate from poor testing at the unit testing stage or an error that occurs while integrating the various programs. 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. The interface should meet the customers requirements or the agreed requirements. 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. Is the software acceptable by the users and managers of an organization? Is the question to be answered in the acceptance testing. 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. 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. 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.
