Given below are two statements: Statement I: Software testing must be recognized as a significant effort, and its planning must begin at the earliest possible time. Statement II: The cost of software testing is an important contribution in determining overall software development costs. In the light of the above statements, choose the correct answer from the options given below
Both Statement I and Statement II are true.
Software testing is one of the most expensive activities in the life cycle; texts such as Pressman note that testing often consumes 30 to 40 percent or more of total project effort, which is why it is planned as a strategy from the requirements stage onwards.
Statement I — True. Because testing is a significant effort, its planning (test strategy, test plan, test case design from requirements and design) should begin as early as possible, not after coding ends. Early planning also catches requirement defects cheaply.
Statement II — True. Since testing takes a large share of effort, its cost is a major input when estimating the overall development cost; cost models explicitly allocate effort to testing and integration.
Since both statements hold, the choices claiming that either statement (or both) is false do not fit.
Both Statement I and Statement II are true. option is correct.
