Abstract :
Generally speaking, we think of testing as a laboratory exercise, a carefully controlled process. However, many products cannot be thoroughly tested solely in the structured environment and process of a laboratory procedure-based evaluation. Certainly, most products require evaluation in the laboratory, at least for initial assessment and debugging. While many environments can be reasonably reproduced in the laboratory, there are environmental and physical interactions that cannot be satisfactorily reproduced artificially; they need to be found in the “real world.”
