Domain Testing: Divide and Conquer - Testing Education

All-Pairs Combination Testing
� You have to order the test case values corresponding
to each succeeding variable such that the final
ordering corresponding to the variable, results in
each value of the variable being paired with each
value of every preceding variable.
� It might be required to backtrack (if other ordering is
possible) if the current ordering makes it impossible
to achieve the above mentioned end result.
� If, no matter what ordering you try and no matter
how much you try to backtrack and redo the things,
the end result (all-pairs) in not achieved then
additional combinations might have to be added.
Refer Appendix B: Guidelines for filling in “all-pairs combination”
table.
