The numbers in the test are all unique. If you use the same values

#define CONFIGURE_MAXIMUM_PERIODS 3
#define CONFIGURE_MAXIMUM_REGIONS 3

how can to ensure that for example the configurations for periods and 
regions are not switched?

If you don't want to use unique numbers, then the test should be split 
up to test each configuration option individually. Who has time to do 
this just to enable this test on a very low end BSP?
