recycler: unit tests - Add reclaim policy to newVolume() call. - Implement reactor Volumes().Get(). - Implement mock volume plugin. - Add recycler tests. - Add a synchronization condition to controller.scheduleOperation - we need to pause the controller here, let the test to do some bad things to the controller and test error cases in recycleVolumeOperation. Test framework gets more and more complicated... But this is the last piece, I promise.

PV Controller: fix recycling In the situation when a PVC is deleted and a new one with the same name bound to a different PV the "old" PV may fail to recycle since it's associaded with a PVC that is detected as being in use. This may cause the recycler processes to hang.

recycler: unit tests - Add reclaim policy to newVolume() call. - Implement reactor Volumes().Get(). - Implement mock volume plugin. - Add recycler tests. - Add a synchronization condition to controller.scheduleOperation - we need to pause the controller here, let the test to do some bad things to the controller and test error cases in recycleVolumeOperation. Test framework gets more and more complicated... But this is the last piece, I promise.

// Test multiple calls to syncClaim/syncVolume and periodic sync of all
// volume/claims. The test follows this pattern:
// 0. Load the controller with initial data.
// 1. Call controllerTest.testCall() once as in TestSync()
// 2. For all volumes/claims changed by previous syncVolume/syncClaim calls,
// call appropriate syncVolume/syncClaim (simulating "volume/claim changed"
// events). Go to 2. if these calls change anything.
// 3. When all changes are processed and no new changes were made, call
// syncVolume/syncClaim on all volumes/claims (simulating "periodic sync").
// 4. If some changes were done by step 3., go to 2. (simulation of
// "volume/claim updated" events, eventually performing step 3. again)
// 5. When 3. does not do any changes, finish the tests and compare final set
// of volumes/claims with expected claims/volumes and report differences.
// Some limit of calls in enforced to prevent endless loops.
