The tasks of this Part are:
N. Analyze independent variables that should be tested together.
O. Analyze variables that hold results.
P. Analyze non-independent variables. Deal with relationships and constraints.
Many variables are inherently multidimensional.33 Other variables are distinct, but after testing the individual variables on their own, you might test them together, treating them as if they were one multidimensional variable.
We test variables (dimensions of a variable) together to expose errors that only a combination of their values will trigger.
In this book, multivariable testing, multidimensional testing and combination testing mean the same thing. As we see it, any test ...
