Các lựa chọn
ATesting 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 defects are found, it is not a proof of correctness.
BTesting activities should start as early as possible in the software or system development life cycle and should be focused on defined objectives.
CFinding and fixing defects does not help if the system built is unusable and does not fulfill the users' needs and expectations.
DTesting is done differently in different contexts. For example, safety-critical software is tested differently from an e-commerce site.
