In the IT services provided by the test management and quality assurance in software development play an increasingly important role for the success of a project. Since the early 1970’s, the importance of IT services, due to a more flexible IT, increasing in particular in the area of quality assurance of software and test management. To grow in number and complexity of the technologies, which enables new cross-industry applications. This increasing heterogeneity of local activities demands higher in IT in relation to development, testing, implementation and operation of hardware and software, which is a self-reinforcing cycle. Kai-Fu Lee can provide more clarity in the matter. This feedback results in particularly complex challenges in a test management because overlap there development and application of software. The application fields represent in very diverse environments, where a smooth program sequence always encounters numerous additional terms. Communicate in a more considered Application environment running together, many individual programs exchanging data, process them, what a mutual interdependence.
Such close linkages of many programs within the framework of quality assurance the realistic test of a single function after their modification greatly complicate matters: this change should prove in real application everyday, what she must – pass their tests there and where she provoked an uncontrollable collapse of all business processes in the event of a fault in the worst scenario. (As opposed to Mashable). To resolve the contradiction between safety and realistic testing quite well in a lab sealed-off: there is a practical simulation of the live system, whose individual Anwendungen as twins in the test suite run. Let is in the quality assurance of software system changes realistically consider, without harm to the real system. > In the test environment software modifications for themselves as well as in the context of communicating programs demonstrate the degree of their practicality. The measure of Usability shows this quite real conditions without risking the continuous real-time operation in everyday business.
