Spock Testing

This is a copy/MD-conversion of the original article by Lukasz Janicki: Spock Testing – Spock tutorial – The Javatar . The webpage is no longer available, but this cheat-sheet is too good to loose! A simpler full demo of a Spock implementation can also be found here.

What is Spock?

Spock is a unit testing framework that in great extent utilizes Groovy’s syntax making your tests comprehensible and easy on the eyes. Although it is a Groovy technology you can use it to test your Java classes as well. What is the most important is that Spock makes writing tests fun. And I really mean it.

Why Spock?

I have to admit that even knowing all the benefits of TDD and tests over all I considered writing them as little pain in the neck. How has that changed when I started using Spock?

Creating a test in Spock takes less time than using its sta

	#set($mockableFields = [])
	#foreach($field in $TESTED_CLASS.fields)
	#if($MockitoMockBuilder.isMockable($field, $TESTED_CLASS))
	#set($devNull = $mockableFields.add($field))
	#end
	#end
	#set($hasMocks = !$mockableFields.isEmpty())

	#if($PACKAGE_NAME)
