Independent Testing Spectrum of independence: -No independent testers,developers test their own code -Independent testers within the development teams -Independent test team or group within the organization, reporting to project management or executive management -Independent testers from the business organization or user community -Independent test specialists for specific test targets such as usability testers,security testers or certification testers -Independent testers outsources or external to the organization 同濟大学 TONGJI UNIVERSITY Software Testing 15/6/84

Software Testing Independent Testing 15/6/8 4 Spectrum of independence: – No independent testers, developers test their own code – Independent testers within the development teams – Independent test team or group within the organization, reporting to project management or executive management – Independent testers from the business organization or user community – Independent test specialists for specific test targets such as usability testers, security testers or certification testers – Independent testers outsources or external to the organization

Why independence? For a complex or safety critical projects: -Multiple levels of testing -Some or all of the levels done by independent testers Development staff may -Participate in testing,especially at lower levels -Limit their effectiveness since lack of objectivity Independent tester should have clear direction -Have the authority to require and define test processes and rules -Take on such process-related roles 同濟大学 SoftwareTesting 15/6/8 5 TONGJI UNIVERSITY
