On input profile selection for software testing

Analyzes the effect of input profile selection on software testing using the concept of a fault detectability profile. The optimality of the input profile during testing depends on factors such as the planned testing effort and the fault detectability profile. To achieve ultra-reliable software, it is preferable to select the test input uniformly among the different input domains. On the other hand, if the testing effort is limited due to cost or schedule constraints, one should test only the highly used input domains. Use of an operational profile is also needed for the accurate determination of operational reliability
