= Invoking a deployed function with a test event
|
|
|
|
You can use the `kn func invoke` CLI command to send a test request to invoke a function either locally or on your {product-title} cluster. You can use this command to test that a function is working and able to receive events correctly. Invoking a function locally is useful for a quick test during function development. Invoking a function on the cluster is useful for testing that is closer to the production environment.

** The `kn func invoke` command only works when there is either a local container image currently running, or when there is a function deployed in the cluster.
|
|
** The `kn func invoke` command executes on the local directory by default, and assumes that this directory is a function project.
