TermsExhaustive testing PrinciplesA number of testing principles have been suggested over the past 40 years and offer general guidelines common for all testing. Principle 1 - Testing shows presence of defectsTesting can show that defects are present, but cannot prove that there are no defects. Testing reduces the probability of undiscovered defects remaining in the software but, even if no defec..

Terms Debugging, requirement, review, test case, testing, test objective.. BackgroundA common perception of testing is that it only consists of running tests, i.e executing the software, This is part of testing, but not all of the testing activities. Test activities exist before and after test execution : activities such as planning and control. choosing test conditions, designing test cases and..

Termsbug, defect, error, failure, fault, mistake, quality, risk 1.1.1 Software systems contextSoftware systems are an increasing part of life, from business applications (e.g banking) to consumer products (e.g cars).
