Two new API integration tests, both targeting production-correctness
invariants worth locking down:
- free_purchase_issues_license_inline: exercises the price=0 shortcut
(price_sats_override=0 on a "free" tier policy). Verifies the daemon
synthesizes a settled invoice locally, issues a license inline, and
the inlined license_key validates round-trip via /v1/validate.
- webhook_settles_invoice_and_issues_license_idempotently: the most
important new test in this set. A pending invoice + an InvoiceSettled
webhook → license issued, status flipped. Re-delivering the SAME
webhook (which providers DO retry, sometimes aggressively) must NOT
duplicate the license. A duplicated license here means duplicated
revenue and duplicated revocation surface area — both bad. This test
pins the invariant.
MockPaymentProvider added to tests/api.rs: a test-only PaymentProvider
impl that bypasses HMAC verification and parses test-supplied JSON
bodies into ProviderWebhookEvent variants. Lets us drive deterministic
settle/expire/invalid events without a real BTCPay roundtrip. Never
compiled into the production binary.
Paid-purchase test deferred: purchase::start still uses the legacy
state.btcpay_client() compat accessor that downcasts to the concrete
BtcpayProvider, which the mock can't satisfy. Documented inline. Slots
in trivially after the trait migration on the v0.3 backlog.
Version bump to v0.1.0:42 with release notes covering everything since
:41 was published: lib.rs library refactor, the original 5 API tests
from 81066df, the 2 new ones above, KEYSAT_INTEGRATION.md restoration.
No daemon-behaviour changes for operators; straight drop-in upgrade
from :41.
Test count: 20 (9 unit + 4 migration + 7 API), up from 13 in :41.
