These fixtures were added in 4aa2ac1b52.
The fixture name mentions renewal as the test function name. But we
don't have any function called test_renewal in test_stripe file. This
likely means the fixtures were accidentally added. Also, deleting all
fixtures and running --generate-stripe-fixtures don't result in these
fixtures getting generated as well.
Previously, when users got a "payment failed" email from Stripe (e.g. if
their card failed on renewal), they would enter in a new card on
/billing#payment-method, and wouldn't find out if the card worked till
Stripe retried the payment 4 days later.
This is a major rewrite of the billing system. It moves subscription
information off of stripe Subscriptions and into a local CustomerPlan
table.
To keep this manageable, it leaves several things unimplemented
(downgrading, etc), and a variety of other TODOs in the code. There are also
some known regressions, e.g. error-handling on /upgrade is broken.
A lot of the seemingly unrelated test fixture changes are because we're
removing a query to stripe in the upgrade path, in cases when the user's
realm has an existing Customer object.
The fixture changes are because self.upgrade formerly used to cause a page load
of /billing, which in turn calls Customer.retrieve.
If we ran the full test suite with GENERATE_STRIPE_FIXTURES=True, we would
likely see several more Customer.retrieve.N.json's being deleted. But
keeping them there for now to keep the diff small.
f52e9d1 ended up not going far enough. Keeping f52e9d1 in place in case we
ever want to go back to that sort of solution.
Also removes the keep argument from test_billing_quantity_changes_end_to_end,
since that test is actually testing the arguments to
stripe.Subscription.save(), not what is returned by Stripe.
Reran every test with GENERATE_STRIPE_FIXTURES = True, which also caused a
few fixtures to get updates unrelated to these changes (likely due to API
updates that hadn't been previously applied).
Also fixes a bug in process_initial_upgrade. If you have a card on file
(e.g. from a previous subscription), and try to upgrade by billing by
invoice, neither the if nor the elif condition applies.
Was hoping to do this after adding timestamp normalization to
normalize_fixture_data, which would have turned this into a <10 line
diff. There is a potentially material change in this API upgrade though
(around how invoices are handled), so just doing it now.
This makes a few other changes to the fixtures as well. Most are from API
updates, though I'm not sure why "Zulip Cloud Standard" got changed to
"Zulip Cloud Premium".

This will improve both the maintainability and accuracy of the fixture
data. It also makes it less scary to upgrade Stripe API versions.
