-=== Constraints / Rules ===+=== Domain Expression === 
 +Domain values for non-//Derived// variables must be static values. 
 + 
 +For //Derived// variables, //Domain// must have exactly one value, which can be static value or //groovy// expression. Below is a simple example to calculate the insurance premium credit of $100 given to good student age < 20: 
 + 
 +   (Age < 20 && GoodStudentStatus)?100:0 
 +    
 +You may use plugin reference in //Domain// value/expression which will be evaluated during  [[#EXECUTE ]]. For example: 
 + 
 +   $VAR.adminUsername              $VAR.adminPassword 
 +   $VAR.normalUsername             $VAR.normalPassword 
 +   $VAR.supervisorUsername       $VAR.supervisorPassword 
 +    
 +For more complex scenario: 
 +   $UTIL.toJSON($VAR.order1Obj) 
 + 
 +where order1Obj is a groovy/java object that is defined/created in //DATA// [[#SCRIPT]]. 
 + 
 +Use [blank] to encode blank string and [null] for null string/object.

 +==== Constraints / Rules ====
 When designing test data using combinatorial testing techniques, we often need to remove or avoid certain combinations as they are either unfeasible or unnecessary for whatever reason.  You can remove these unwanted combinations manually after the test combinations have been generated, but that's tedious and prone to errors. Depending on number of test combinations generated, manually removing unwanted combinations may even be impossible due to large volume. When designing test data using combinatorial testing techniques, we often need to remove or avoid certain combinations as they are either unfeasible or unnecessary for whatever reason.  You can remove these unwanted combinations manually after the test combinations have been generated, but that's tedious and prone to errors.

 +
 +There are two types of scripts: //MAIN// and //DATA//.
 +
 +//MAIN// script is the main program which executes the test cases.
 +
 +//DATA// script is used to instantiate and create objects (groovy/java) to be used in test case execution. 
 +For example, you may create a purchase order object to be posted to REST api:
 +   $VAR.order1 = [product: 'cookie', price: 2.00, quantity: 20]
 +
 +The order object "order1" is assigned to $VAR.  It can then be used in //Domain// expression as:
 +   $UTIL.toJSON($VAR.order1)
 +
 +//INIT// script is for initialization of variables, e.g. environment, user name, password, etc., the variables that may need to be changed from execution to execution.
