C. the number of faults detected during inspection versus the number found in production once the product was put into operation
D. the number of faults detected per 1000 lines of code (kLOC)
E. the number of faults detected per page

D. the number of faults detected per 1000 lines of code (kLOC)
Execution-based testing is a process of inferring certain behavioural properties based, in part, on the results of executing the product in a known environment with selected inputs (Goodenough, 1979). What is the problem with this approach?
A. The tester has few clues to help find any faults: a set of inputs and a corresponding set of outputs.
B. The environment is uncertain - there may be faults in the hardware or software (e.g. operating system) environment.
C. In a real-time environment there is little control over the inputs. In a data processing environment the data used by tester may not be representative of that used by the end-users.
D. All of these are problems.
E. None of these are problems.
In a real-time environment there is little control over the inputs. What can be used to partially circumvent this problem? A:
A. real-time operating system
B. simulator
C. data base management system
D. virtual reality synthesiser
E. configuration control tool
Utility is:
A. the extent to which the user's needs are met when a correct product is used under conditions permitted by its specifications.
B. a measure of the frequency and criticality of product failure.
C. a function of the range of conditions under which it will operate.
D. the extent to which the product meets its constraints with regard to response time or space requirements.
