# `Hemdal.Notifier.Mock`
[🔗](https://github.com/altenwald/hemdal/blob/v1.4.0/lib/hemdal/notifier/mock.ex#L1)

Let us perform tests using a notifier which we can control. It's working
injecting inside of the metadata the PID of the process where the
notification should be triggered.

Inside of the configuration we have to inject the notifier with the
corresponding information, it's important to choose a backend which let us
use the PID as data. If you see `Hemdal.CheckTest` you can find a way
about how to do this.
