Software testing is the most crucial in website or software development process. 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. 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.

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.

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. 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. The functionality of the system is done in their category of software testing methods.

Interface testing is a method that can be used to categorize the basic types of testing. 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. Interviews and questionnaires answering are the main methods used to collect data about the acceptance of the software.

Non-functionality testing is done for the performance factor. Adding a lot of work to the software system and checking its performance is one basic way of non-functionality testing. In maintainability testing the recovery of the system is tested and checked by the system tester such that it may reduce the maintainability cost. 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.
