no need to use DefaultWorkloadList() at all here, and by using it you make the tests fail if we change the contents of the default workload list. You can just create your own workload list instance and pass that, e.g. like this: https://github.com/cloudfoundry-community/pat/blob/9c500c9c7ab84f8e5b93dbef34f41c2ba95a18fb/workloads/workloads_test.go#L17
