Fundamentals of Software Testing

Software testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test.[1] Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include the process of executing a program or application with the intent of finding software bugs (errors or other defects), and verifying that the software product is fit for use.

KEY ASPECT OF TESTING QUALITY SOFTWARE 1. Functionality 2. Reliability 3. Usability 4. Efficiency 5. Maintainability 6. Portability

Software testing is a vast subject. There are software applications and system engineered for numerous domains and industries, and for a tester, every testing project is a new challenge because he has to understand the client’s point of view and the domain before moving on with testing activities. From project to project, a tester may have to change the testing methodologies as well. It is therefore very important to keep the fundamentals right. Getting the fundamentals right in the first place is biggest prerequisite to become successful in software testing.

Why Software Testing Is Necessary?

An error, defect or a bug can be caused by developers. It is not intentional but considering the complexity with which various software are being developed these days, it is quite possible for a developer to misunderstand and implement wrong logic and produce wrong code.

Testing is necessary because it helps us in identifying the faults in software. Once these defects have been detected they can be easily rectified and quality of the software can be improved. So, software testing is necessary so that bug free applications can be developed and delivered. When a company decides to develop software for a client there are certain legal, contractual and industry-specific requirements based on the deal is made. A quality conscious company will definitely include software testing in its best practices.

It is difficult to say how much testing is enough but the fact is that if testing is planned carefully and good test cases are made then it is very much possible to deliver high quality software.

Who Does The Software Testing?

There is often a debate on who should actually test the software. People often question that why developers are not allowed to test. Well, a developer generally checks his code several times before he submits it for testing and still in most cases it is never error free because a developer is generally blind to his own mistakes.

A tester on the other hand looks at software from the point of view of the client. He is unbiased and his focus is only on the specifications and the requirements. So, a tester is able to look into areas that a developer may have ignored. So, the testing should always be carried out by independent testers.

This approach does have some disadvantages. When the development and testing teams are different there is often a communication gap and sometimes, developers become careless towards coding and do not revise their code because they think that it is all a tester’s job thereby increasing the burden on the tester.
