Introduction To Software Testing For The Un-initiated
Many of us do not know what software testers do? For such individuals, it is better to give a brief introduction to software testing so that the work of software tester could be then explained to them.
Software testing is not just sitting down on a computer and trying things. It is more than this and need mental exertion in the form of figuring out ways through which different ways can be evolved using which software can be tested.
These tests can be automated and are repetitive. They can also be run on an instant basis, allowing continuous feedback on the way things work. Testing in such a manner brings more flexibility to your project.
Software testingÂ-both a process and a disciplineÂ-is part of development process of a software. Yet it is a different discipline, it should not be thought its part because software development codes the functionality to meet user needs. It can however be seen as interactive process of validating functionality. This process includes designing tests, executing tests, identifying problems and getting problems completely fixed. The main function of software testing is to identify problems and fix them to enhance quality and reliability. Testing commonly represents forty percent of a software budget. Another form of software testing is called manual testing process. This is generally done by an individual. This type of testing resorts to navigating interfaces, trying to hack the software and submitting information received on such tests that were carried out. But this is slow because of its labor intensive mode. It can only be used in only few software testing processes. Software testing process is intended at detecting errors. It includes all activities meant for judging the attributes or strength of a program. It is not, like other process, done physically in which inputs are taken and outputs are generated. All software testing process differ from each other in the manner they detect errors. Software bugs persist in almost every software module. Different testing tools are applied to handle them. All the values are tested as well as verified. But complete testing is not possible. A complication in further stages has to do with the nature of a program. It is difficult to test the quality but related factors that affect quality can be tested well. Quality deals with three factorsÂ-engineering, functionality and adaptability. These three factors can be considered as dimensions of quality space in the software. The dimension can be cracked down into other component factors. This introduction to software testing would have also suggested that testing methods evolve as the programming and structure of the software developed evolve. Hence, software testing still has a long way to go.
