How to evaluate FallbackPolicy

Hello Everyone, I have built a small chatbot and tested it using separate test file using:

rasa test nlu -u train_test_split/ --model models/20200127-111426.tar.gz

I don’t want to test the intents only, I want to see how is my model performing to the fallback action as well.

let’s say I have 2 intents in my “Greeting” and “bot_name”. Now in this case, test data should also contains these two intents as well. Can I add another intent in my test data like “Fallback” and add some data for it too ?
