How to create the combinations of input variable values
I am performing a black-box testing. The input data is a set of variables. The types and value ranges of the variables are known. Some of them are numeric, some are string, and some arr floats. The perfect situation is to generate all combinations of variable values. However it is impossible, for the numbers of the combinations are infinite.
The altenative way is to generate some equivalent classes. However, the inner logic of the black-box is unknown. The generatation of equivalent classes can only base on the variable values. Does someone know a effective way to analyze variables and generate appropriate equivalent classes?
