Commit
This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
this commit enables the notifier to be started in a test mode. the test mode is enabled via an env var "NOTIFIER_TEST_MODE". in test mode the notifier will send a notification at each poll interval. make targets are provided to start and restart the notifier in test mode. the local dev configuration can be configured accordingly to point to the supported delivery method of your choice.
