 ===== Generate Test Cases ===== ===== Generate Test Cases =====
 +Test generation from combinatorial model is done in [[../data_design_ide#generate | GENERATE]] tab.  Go ahead and select //GENERATE// tab.
 +
 +{{wiki:overview:tut_comb_new_model_gen.png?600}}
 +
 +To generate the test cases,
 +  * select an algorithm {{wiki:overview:tut_comb_algorithms.png?150}}
 +
 +  * click on ▶ next to the algorithm dropdown
 +
 +Generated test cases are listed in //DataTable// as below for //pairwise//:
 +
 +{{wiki:overview:tut_comb_new_model_pairwise_gen.png?600}}
 +
 +You may remove or add additional rows to the //DataTable// as you see fit, even to update values for any rows. However this must be done with caution as any changes to //DataTable// will be lost on next time //DataTable// is re-generated.
 +
 +Feel free to experiment with different generation algorithms.  You must save the changes before you run another generation.
 +
 +When selecting //Mixed// algorithm, you will see an additional section displayed below the header (variable names):
 +
 +{{wiki:overview:tut_comb_new_model_gen_mixed.png?600}}
 +
 +//Mixed// algorithm allows you to selectively apply different interaction strength (pairwise vs three-wise, etc.) for specific subset of variables.
 +
 +We will not cover //Mixed// algorithm here, but you can find more details about //Mixed// algorithm in [[../data_design_ide#generate | Data Design IDE / GENERATE]].

 ===== Make Changes ===== ===== Make Changes =====
 +
 +As you must have figured out that you can easily add additional variables and remove any variables from the model.
 +
 +Other changes are adding, removing and changing the domain values of each variable.
 +
 +Upon any changes to the model, you should always re-generate //DataTable//.
