-====== Tutorial: Automation Scripting - Combinatorial Model ======
-Learning Objectives:
-  * [[#Model scripting]]
-  * [[#Looping DataTable]]
-  * [[#Activating plugins]]
-  * [[#Exporting results]]
-  * [[#Remote Execution]]
-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: ' + $DATASET.getDataRows().size());
-Run the model, you should see following returned and displayed on [[../data_design_ide#execute | IDE Execute]] tab:
-   Total number of rows in DataTable: 10
-===== Looping DataTable =====
-To perform the testing on all rows in DataTable, you must loop through each row in DataTable ($DATASET.getDataRows()). You can do this with //for// loop:
-   for (Map<String,String> row: $DATASET.getDataRows()) {
-      $DATASET.notifyClient(row);
-   }
-===== Activating Plugins =====
-Just like [[scripting_state_model | scripting for State Model]], you need to activate plugins to interact with AUT to perform the testing on each row in the DataTable.
-For this tutorial, activate //Random// plugin, and modify the script to use //$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);
-   }
-Make changes to your script to incorporate the plugin function calls and re-run the model.
-===== Exporting results =====
-When running the model in IDE, you can export/download the execution results in [[../data_design_ide#execute | IDE Execute]] tab.
-After model execution completes, you can export the results by menu //File / Export// or {{wiki:overview:tut_comb_btn_export.png?28}}.
-Try the export and review the result file downloaded.
-If you are running model remotely using [[../integration#rest_apis | REST api]], you may specify the file location to save the execution results, see next section for details.
-===== Remote Execution =====
-You may run your data model remotely using REST api:
-   curl -X POST "http://localhost:8888/api/v1/runtime/dataset/run/sync" -H  "accept: application/json" -H  "Content-Type: application/json" -d "{  \"modelName\": \"MyDataModel_A\",  \"options\": {\"path\": \"Folder_B\", \"outputFile\": \"myOutputFile.txt\"}}"
