Software Testing - Research Paper Example We are dealing with the banking system from Pennywise National Bank. Therefore, experimental design is the best method of testing software (Basili and Selby, 1987). According to Gelperin and Hetzel (1988), we are going to deal with phase models and life cycle models. In the phase models, we have a demonstration and destruction phases. Demonstration ensures that the software satisfies all its specifications. Destruction involves detection of the implemented faults that may lead to errors during the software functioning. In the life cycle models, we have an evaluation and the prevention stages. In the evaluation, one detects requirements, design and implements faults. In prevention, requirements, design and implementation faults are prevented. Review of software requirements is not considered as testing. Prevention testing involves analysis and review besides improvement of the software specifications and design. Moreover, the code is improved before test execution (Gelperin and Hetzel, 1988). We are going to test the coding, structural and functional properties of our software. Code reading will be tested using the stepwise subtraction. The structural testing will be done using 1005 statement coverage criteria. Finally, the functional testing will be done using equivalence partitioning and analysis of the boundary value (Basili and Selby, 1987). The primary goals of testing are; to demonstrate that some parts of the software specifications are functional and meet their tasks, to detect faults and finally to prevent faults. Formerly constructive approach was being used in testing yielding unsatisfactory results in that it contained tests that the software could pass. Currently, the demonstration strategy is being used. Tests always are hypothesized that the software is not perfect in its specifications in that it can not lack even a single fault. A set of test T is built and applied to the software. In the long run, at least a single

History - Assignment Example To what degree do you find his arguments persuasive? (see the box on pg 793) Brezhnev believed that if a country was shifting from Communism to capitalism, it was the duty of those who support Communism to step in and try to stop the shift. He clearly saw it as a good versus evil issue. When Czechoslovakia appeared to be switching to capitalism in 1968, Brezhnev ordered troops to prevent the uprising, and crush the Prague Spring. His arguments are ridiculous. He refused to listen to the will of the people in Czechoslovakia, preferring to kill them instead. The Prague Spring was not the imposition of an invading force; it was the people making a choice for themselves. His policy was also retroactive. This doctrine, espoused by President Harry Truman, suggested that the U.S. would help subjugated people try to free themselves from domination by Communists. At the time it focused on Greece and Turkey, where Communists were trying to take over, but it eventually extended to many other countries. Truman wanted to prevent the Soviet Union from dominating the Third World and he was willing to use American force to do this. Both of these groups were Cold War military alliances. The West had NATO—the North Atlantic Treaty Organization—that included America, Canada, Western Europe, and a few other countries. The Warsaw Pact was the Soviet Union and its allies. Those who foresaw the Cold War turning into a hot war, believed these alliances would fight one another. In each alliance, the countries had mutual assistance pacts. NATO, for example, considered an attack on any NATO country an attack on all of them. This was a crisis that involved the Soviet Union, America, and Cuba. In the early 1960s, the Americans learned that the Russians were putting nuclear missiles on Cuba and point them at the U.S. This led to a serious standoff and a blockade of Cuba. Many believe this was the
