Add spec tests for check_pool
Previously the check_pool method would execute the loop indefinitely as it did not
have a terminating condition. This made it impossible to test. This commit
modifies the check_pool method so that it can take a maxloop and delay parameter
so that it can be tested.
Add spec tests for execute!
Previously the execute! method would execute the loop indefinitely as it did not
have a terminating condition. This made it impossible to test. This commit
modifies the execute! method so that it can take a maxloop and delay parameter
so that it can be tested.
This commit adds the following test helpers:
- MockFindFolder
Returns an mock result object from calling `Vmpooler::VsphereHelper.find_folder(foldername)`
- Use MockRedis instead of using method stubs
- MockLogger
Creates an object which looks like the VMPooler::Logger object but just
ignores all messages. This stops the proliferation of allow(logger).to ....
expectations in tests
- create_completed_vm
Creates the required redis information for a completed VM
- create_discovered_vm
Creates the required redis information for a newly discovered VM
- snapshot_revert_vm
Creates the required redis information to revert a snapshot for a VM
- disk_task_vm
Creates the required redis information to add a disk addition task to a VM
Previously all of the spec tests for VM Pooler were all together in the specs
directory. However some tests require a working local Redis server to operate
and other instead mock all external dependencies. This commit splits the test
files between unit and integration, where integration tests require a working
Redis instance, and unit tests do not. This commit also removes the root
`vmpooler` directory as it is not required. The tests rake test still operates
correctly.
This commit also adds the mock_redis library for testing for the pool_manager.
