# Testing, lint & CI status

## Running

From `licensing-service-startos/licensing-service/`:

```
cargo test                  # all suites
cargo test --test api       # one suite — suites: api crosscheck migrations subscriptions upgrades worker
cargo test <name>           # single test by name pattern
cargo clippy --all-targets  # ~6 style lints (e.g. unnecessary_map_or)
cargo fmt --check           # reports formatting diffs (does not write)
```

## There is no CI

No `.github/workflows`, no Gitea/Woodpecker/Drone config. **Nothing is enforced** —
not `cargo test`, not `clippy`, not `fmt`. The release gate is `publish.sh`.

## Formatting is not clean and not enforced

The tree has never been run through `cargo fmt` (56 daemon files differ) or
`prettier` (37 wrapper files differ). `cargo check` and `tsc --noEmit` pass clean.
If you ever format, do it as a **standalone commit** so the mechanical churn
doesn't bury logic changes.

## Runtime-prepared SQL → tests are the only safety net

`db/repo.rs` queries are `sqlx::query(&format!(...))`, prepared at runtime, so bad
or ambiguous columns 500 only when executed. A real prod regression (every paid
purchase returning 500 on `:52`) shipped this way because the new merchant-profile
resolution path had no passing test. When adding/altering a repo query, add a test
that actually executes it. See [payments](payments.md).

## Driving the purchase / settle path — the provider seam

Integration tests are a separate crate, so `#[cfg(test)]` doesn't reach the lib
and `payment::build_provider` only ever makes real BTCPay/Zaprite clients. To
drive the real resolver (`resolve_provider_for_profile_rail` /
`payment_provider_by_id`) with a `MockPaymentProvider`, set the always-compiled
`AppState::provider_override` field (`None` in production; honored by
`provider_from_row`). `install_mock_provider` / `make_test_state_with_mock_provider`
wire a mock into BOTH that field AND the legacy `state.payment` singleton (the
back-compat `/v1/{kind}/webhook` route reads the singleton), and seed a real
`payment_providers` row on the default profile so profile/rail/row resolution
still runs for real. `MockPaymentProvider::new_unconfirmed()` /
`new_status_unavailable()` vary the `get_invoice_status` answer to exercise the
webhook settle-confirmation guard (see [payments](payments.md)).

The 3 `:52`-era known-failing tests are **resolved**: the two `paid_purchase_*`
greened via the seam, the dead `payment_provider_preference_round_trip` deleted.
api suite is now **54 pass / 0 fail** (47 after the `:52` fixes, plus the
post-`:54` scoped-key role-boundary and settle-tripwire tests); all other
suites green.

## Cross-language wire-format tests

The LIC1 format is verified across SDKs separately — see
[crypto-wire-format](crypto-wire-format.md).
