WooCommerce Subscriptions

When testing subscriptions, I’d like to be able to execute subscription renewals almost on demand, and I’d like to do so such that the subscription processing goes through 100% of the normal code path that handles scheduled renewals. The methods available to force a subscription early include the “renew now” feature (which doesn’t include advancing the next payment date) and putting the subscription on 1-day renewal (which is inefficient, time-wise). I suggest adding a renewal option defined in hours or even minutes, so that I could create a subscription that, at most, I have to wait until the next hour to process and see results.
