Test Generation from Requirements
each combination might be able to generate more than one test when
a condition in the cause–effect graph can be satisfied in more than one
way. For example, consider the following cause:
C : x < 99.
The condition above can be satisfied by many values such as x = 1and
x = 49. Also, C can be made false by many values of x such as x = 100
and x = 999. Thus, while generating tests using columns from a decision
table, one might have a choice of values or input variables.
While one could always select values arbitrarily as long as they satisfy
the requirement in the decision table, it is recommended that the choice
be made so that tests generated are different from those that may have
already been generated using some other
