-====== Tutorial: Automation Scripting - Combinatorial Model ======
-Learning Objectives:
-  * Model scripting
-  * Looping through DataTable
-  * Activating plugins
-  * Persisting and exporting results
-This tutorial assumes that you are familiar with how to create a Combinatorial Data Model and have created a simple model with at least 2 variables named Field1 and Field2 and have generated the DataTable.  Please refer to [[comb_data_modeling | Combinatorial Data Modeling]] if you need assistance in creating the model.
-===== Model scripting =====
-[[https://groovy-lang.org/syntax.html | Apache Groovy]] script is the scripting language for your models.
-//Groovy// script is syntactically very similar to most of programming language that allows you to create classes, functions and basic logic and arithmetic operations.
-Unlike [[scripting_state_model | scripting for State Model]], you just write your script right in [[../data_design_ide#script | SCRIPT]] tab. In your script you would just loop through the rows in DataTable.  Below is an example of script:
-   $DATASET.notifyClient('Total number of rows in DataTable: ' + $DATASET.getDataRows().size());
-Run the model, you should see following returned and displayed on IDE:
-   Total number of rows in DataTable: 10
-===== Activating Plugins =====
-Just like [[scripting_state_model | scripting for State Model]], you need to activate plugins to interact with AUT to perform the testing on each row in the DataTable.
-For this tutorial, activate //Random// plugin, and modify the script to use //$RANDOM.randNum(...)// to determine the failure/success as below:
-   for (Map<String,String> row: $DATASET.getDataRows()) {
-      if ($RANDOM.randNum(0,10) > 5) {
-         row._result = "Successful run on " + row.Field1 + ", " + row.Field2;
-         row._status = true;
-      }
-      else {
-         row._result = "Failed run on " + row.Field1 + ", " + row.Field2;
-         row._status = false;
-      }
-      $DATASET.notifyClient(row);
-   }
