 * Molecule is used to test the various functionalities of the role. The recommended version of Molecule to test this role is `3.3`.
 * Instructions on how to install Molecule can be found in the [Molecule website](https://molecule.readthedocs.io/en/latest/installation.html). _You will also need to install the Molecule Docker driver._
+* To run the NGINX Plus/App Protect config Molecule tests, you must copy your NGINX Plus/App Protect license to the role's [`files/license`](https://github.com/nginxinc/ansible-role-nginx-config/blob/main/files/license/) folder.
+
+You can alternatively add your NGINX Plus/App Protect repository certificate and key to the local environment. Run the following commands to export these files as base64-encoded variables and execute the Molecule tests:
+
+```bash
+export NGINX_CRT=$( cat <path to your certificate file> | base64 )
+export NGINX_KEY=$( cat <path to your key file> | base64 )
+molecule test -s plus
+```
