              Test mutations let you author unit tests with different expected results. The mutation 
              id is passed as the value of the WIXLUX_RUNNING_MUTATION property. Your custom action, 
              typically in an '#ifdef DEBUG' block, can retrieve the WIXLUX_RUNNING_MUTATION property 
              and hard-code different behavior based on the mutation. To author test mutations, use 
              the Mutation element with UnitTest elements as children.
