Testing must be done to ensure that the errors and faults in the software are eliminated. Testing is all about identifying faults in a software product. 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. 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.
More on the software testing methods is the unit testing. 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. The testing can be entrusted to an organization or a single tester. It is advisable to correct the errors immediately they are identified. Ensure that all errors are eliminated in the unit testing stage.
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. These group of the integrated units should be functionable and should lack errors. 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 another category of software systems. The interface should meet the customers requirements or the agreed requirements. 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. The acceptance testing is done by interviewing the users of the software system and the owners or the shareholders of the organization.
Operation testing is for genuinely assure that the system functions as required by the users. Adding a lot of work to the software system and checking its performance is one basic way of non-functionality testing. 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. 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. 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.
