+# Stripe
+
+The app uses Stripe to handle payments for users wishing to upgrade their membership from standard to premium.
+
+You can test Stripe's JavaScript integration without being dependent on Stripe's test environment network availability. For reliable, faster tests, its usually a good idea to make your tests work independently of any 3rd party environments.
+
+To remove the dependency on Stripe's environment, the test suite relies on Puffing Billy mocking the Stripe HTTP responses in the browser.
