Description

This feature maybe helpful when unit testing and a Category has already been applied.

Supplied TestCase:

import groovy.util.GroovyTestCase

class Greeter{
   String greet(){
      return "Hello Groovy!";
   }

   String say( String s ){
      return "I say: "+ s;
   }
}

class CategoryOne{
   static String greet( Greeter self ){
      return "Hello from One";
   }
}

class CategoryTwo{
   static String greet( Greeter self ){
      return "Hello from Two";
   }
}

class TestCategories extends GroovyTestCase{
   void testGreeter_plain(){
	   def greeter = new Greeter();
	   assertEquals "Hello Groovy!", greeter.greet();
	}

	void testGreeter_withOne(){
	   def greeter = new Greeter();
	   assertEquals "Hello Groovy!", greeter.greet();
	   use( CategoryOne.class ){
	      assertEquals "Hello from One", greeter.greet();
	   }
	   assertEquals "Hello Groovy!", greeter.greet();
	}

	void testGreeter_withTwo(){
	   def greeter = new Greeter();
	   assertEquals "Hello Groovy!", greeter.greet();
	   use( CategoryTwo.class ){
	      assertEquals "Hello from Two", greeter.greet();
	   }
	   assertEquals "Hello Groovy!", greeter.greet();
	}

	void testGreeter_withOneAndTwo_nested(){
	   // fails!
	   def greeter = new Greeter();
	   assertEquals "Hello Groovy!", greeter.greet();
	   use( CategoryOne.class ){
	      assertEquals "Hello from One", greeter.greet();
	      use( CategoryTwo.class ){
	         assertEquals "Hello from Two", greeter.greet();
	      }
	      assertEquals "Hello from One", greeter.greet();
	   }
	   assertEquals "Hello Groovy!", greeter.greet();
	}
}
