Q1. Why software needs to be tested?
Ans. Every software product needs to be tested since; the development process is unable to produce defect free software. Even if the development process is able to produce defect free software, we will not be able to know unless & until we test it. Without testing it, we shall not be having enough confidence that it will work. Testing not only identifies and reports defect but also measures the quality of the product, which helps to decide whether to release the product, or not.
Q2. What is the reason that Software has Bugs?
Ans. Following factors contribute to the presence of bugs in the software applications:- a. Software development tools like visual tools, class libraries, compilers, scripting tools, etc. usually introduce their own bugs in the system. b. To err is human. Likewise programmers do make mistakes while programming c. In fast-changing business environments continuously modified requirements are becoming a fact of life. Such frequent changes requested by the customer leads to errors in the application already nearing completion. Last minute design changes leads to many chaos like redesign of the whole system, rescheduling of engineers, scrapping of the work already completed, fresh requirements of compatible hardware etc d. A quickly written but poorly documented code is bound to have bugs. It becomes difficult to maintain and modify such code that is badly written or poorly documented.- its tough to maintain and modify code that is badly written or poorly documented; the result is bugs. In many organizations management provides no incentive for programmers to document their code or write clear, understandable, maintainable code. In fact, it’s usually the opposite: they get points mostly for quickly turning out code, and there as jobs security if nobody else can understand it (if it was hard to write, it should be hard to read). e. When project deadlines come too close
