How can I test a recurring webhook subscription without waiting for it to expire?

[Ileriayo]

Hello,

I need to run a process whenever Shopify subscription has been renewed.

I checked here and found that I can subscribe to the topic APP_SUBSCRIPTION_UPDATE.

1. Having created a webhook subscription with the above topic, how can I test (simulate) a recurring subscription without waiting for the current subscription to first expire after 30 days? Note: If I cancel the subscription, the status changes from Active to Cancelled (from my research). 

2. It is extremely necessary that I am able know when a subscription has been renewed. Does the app subscription status first change from Active to Expired and then renews and becomes Active again?  

3. Am I using the right webhook topic to check for renewals of app subscription?
