I have required fields to fill in before somebody clicks submit in a computer program, but I want to tell our testing team that we need to test to make sure the program does not submit unless all required fields are filled in. But, I want to test all of the combinations of the required fields, except for the combination where I fill all the fields in because that should always work.
Is this expressed as
n choose (n-1), where n is the number of required fields?
If so, do you know if there is any software program we could use that will generate a true/false table of combinations if we supply the names of the variables to automate a list for us so that this can be printed out? It would have to be something free, but I just need a basic program.
