Exact Validation Testing in Appliacation

Hello,

Im starting writing test for my Applications and I was wondering if there is any easy (simple) way of Testing all different types of validation constellations than writing an own test for it.

I'll try to explain what I mean by that.

Let's Say I have a Form with 5 Inputs.

• two of them are Required ( first name, last name)

• two (phone, mobile) require one of them be filled

and

• one is optional (mail)

In my mind I would like to test every possible constelation a user can fill out. What will result in around 32 Test only for this small Form.

Is this the common Practice or is there a more efficient way of testing?

Best regards Mike
