Using pairwise and t-

way for scripted testing and exploratory testing

Whenever generating an optimized dataset (i.e., multiple "rows" of values for the parameters) this will be typically used to data-drive a scripted test case (e.g., a "manual" test composed of steps, or an automated test script).

...

Generating these combinations is useful not only for this testing approach though.

Pairwise and t-wise testing way testing don't tell us how to actually perform testing; it just generates the combination of parameters. Therefore, we can use this technique also if choose to adopt a more exploratory testing approach, for example for certain configurations of hardware/software.

Challenges

Pairwise or t-wise way testing even though useful, it's not a silver bullet.

Some challenges or limitations to be aware of, include:

1. test oracle: this technique doesn't address finding the proper test oracle for the generated scenarios. How do we know the scenario is behaving as expected? How do we know that a given scenario has issues or not?
2. modeling: depicting a "good" model requires the intervention of testers. Testers with the help of other team members are the ones able to figure out representative and important scenarios to model , their parameters, the values for those parameters, constraints, etc.
