Domain Testing: Divide and Conquer - Testing Education

1. Indicate what variables you would select for doing all-pairs
combination. Justify your selection.
2. Indicate which test cases of the chosen variables you will use for
doing all-pairs. Justify your selection.
3. Show all iterations. Give relevant comments when you backtrack
and redo any ordering.
Subject A2529S1
• Picked 3 variables: Slides Sized For, Slide Number and Notes Orientation. The subject
mistakenly believed that Slide Orientation was determined by Slide Sized For – actually
for each size, you can specify portrait or landscape.
• For the values of Slides Sized For, the subject used the 11 enumerated values. But one of
these is Custom, which allows the full range of sizes. This is where the boundary cases (1"
x 1" and 56" x 56") can be entered. If you're interested in testing slide size, these are
certainly two key cases to include. If I was to test the full enumerated set, I'd include the 2
custom values, for 12 cases total.
• For the values of Starting Slide Number, the subject specified 6 values.
o One test required an (unspecified) 1 digit number; another an (unspecified) 4 digit
number
o One test required an (unspecified) test that included a 1; another an unspecified
number that included 9
o One test required 1; another required 9999.
o Clearly, 1 and 9999 meet the other requirements, so there are 2 cases to test here,
not 6.
• For the values of Notes Orientation, there are 2 cases, as the subject specified.
• Conclusions to this point:
o This subject is working mechanically without thinking about the variables being
tested.
o No one with work experience in this type of testing would do this, because if they
had ever done it, they would have realized how much time they were wasting
when they tested from this matrix.
o Additionally, the failure to realize that 1x1 and 56x56 are interesting cases here
suggests to me that boundary analysis doesn't come naturally to this subject.
o This final piece of work would lock down my conclusion that this subject doesn't
have the understanding that I would expect of a tester with a year of practical
experience with domain testing.
