EFFICIENT RESOURCE SHARING

A method comprising: identifying, by a resource manager, a resource of a storage system, the resource being one which a testing system lacks permission to use for testing the storage system; adding, by the resource manager, the resource to a group of resources which the testing system is permitted to use for testing the storage system, wherein adding the resource to the group includes granting the testing system a temporary permission to use the resource for testing the storage system; allocating the resource to a test that is performed by the testing system; and removing, by the resource manager, the resource from the group wherein removing the resource from the group includes revoking the temporary permission.
