Adds tests, three test-kit builders and goldens only; no production file
changes.
TestBillingListsGolden compares each list's data, in the default and the
all state, with a file under testdata/operator_billing for a fixture of two
organizations and four billing accounts (live, unrecorded, unmapped, test),
each with a subscription, an invoice and a payment. Each file was read
against the fixture before it was committed: the test-mapped row is hidden
by default with the line counting one, shown with the test badge in the all
state, the unmapped row reads not_mapped, and every row names its own
organization.
TestBillingListsKeepTheirFallbacksWhenAReadFails pins, per list, that a
failed organization read leaves the name empty and a failed mapping read
shows not mapped.
TestLookupInvoiceCandidatesNameTheirOrganizations pins the invoice
candidates' organization names and the organization id as their fallback.
The read-count table gains billing accounts, billing subscriptions, billing
invoices, billing payments and lookup rows. Each grow adds its rows on a new
organization named from a counter, and the lookup row is sent as an htmx
request. Measured per row: 2 for each billing list, 1 for the lookup, as
predicted.
world gains MapAccount, MapSubscription and MapPayment, which record no
environment, beside MapInvoice.
Names and results of ./internal/server and ./internal/testkit/... match the
parent apart from the new tests, which pass: TestBillingListsGolden and its
twelve subtests, TestBillingListsKeepTheirFallbacksWhenAReadFails and its
twelve, TestLookupInvoiceCandidatesNameTheirOrganizations and its two, and
the read-count subtests billing_accounts, billing_subscriptions,
billing_invoices, billing_payments and lookup. A second run without -update
leaves the tree unchanged, and the tests pass three runs in a row after a
reset. Thirty-two edits to the list code and the lookup, each breaking one
fact, fail the test that names it.
Unprobed: the goldens pin the loaders' other fields (dates, amounts, statuses,
account names, payment method, invoice numbers, Overdue, the pager and the
absence line) with no break, because no later section edits the code that fills
them; the breaks probe the fields the mapping and naming changes move.
