Testing

Just a small list of tests to run before release:

1. Create workflow with "Subscription note added" trigger and a trigger text.
2. Add 6 actions (in this order):
   • Update schedule - 6 months
   • Update currency - HKD
   • Update product - Choose a product and add a custom name/price and a new quantity
   • Remove shipping - All shipping methods
   • Add shipping - Choose a shipping method and add a custom name/cost
   • Update shipping - Same shipping method as (5), but change the custom name/cost
3. Create a subscription
   • Schedule it for something other than months
   • Add the product chosen in the workflow
   • Add a shipping type other than the one chosen in the workflow
4. Add a note with the trigger word.
5. Confirm the changes:
   • New currency
   • New subscription schedule
   • Updated product name, cost and quantity
   • The updated shipping method should be the only one present
