# MNW Server Tests |
| 2 |
|
| 3 |
## Prerequisites |
| 4 |
|
| 5 |
- PostgreSQL running locally (default: `postgres://localhost/postgres`) |
| 6 |
- Set `TEST_DATABASE_URL` if using a non-default admin connection |
| 7 |
|
| 8 |
## Test Types |
| 9 |
|
| 10 |
### Unit Tests (`cargo test --lib`) |
| 11 |
|
| 12 |
1,912 tests covering pure logic: pricing, validation, formatting, enums, error handling, CSRF, RSS, file scanning, import parsing, etc. No database required. Runs in ~2.5s. |
| 13 |
|
| 14 |
### Integration Tests (`cargo test --test integration`) |
| 15 |
|
| 16 |
1,226 tests across 123 workflow modules. Each test gets an isolated PostgreSQL database cloned from a shared template (migrations applied once, then reused across runs while migration-current). ~433s at `--test-threads=8`. |
| 17 |
|
| 18 |
**Harness features:** |
| 19 |
- In-process Axum app (no network, uses `tower::ServiceExt::oneshot`) |
| 20 |
- Cookie-aware HTTP client with automatic CSRF token management |
| 21 |
- Mock Stripe (`MockPaymentProvider`), captures checkout sessions, supports webhook signing |
| 22 |
- Mock email (`MockEmailTransport`), captures all sent emails for assertion |
| 23 |
- Mock S3 (`InMemoryStorage`), in-memory file storage |
| 24 |
- Direct SQL helpers for test setup (`grant_creator`, `grant_tier`, `connect_stripe`, etc.) |
| 25 |
|
| 26 |
**Harness constructors:** |
| 27 |
- `TestHarness::new()`: DB only (fastest, for auth/CRUD tests) |
| 28 |
- `with_storage()`: adds in-memory S3 |
| 29 |
- `with_mocks()`: mock Stripe + email (for payment flow tests) |
| 30 |
- `with_stripe()`: real Stripe SDK with test keys |
| 31 |
- `with_admin()`: pre-created admin user |
| 32 |
- `with_storage_and_scanner()`: file scanning pipeline |
| 33 |
- `with_git_repos(path)`: git repository support |
| 34 |
- `with_admin_storage_and_scanner()`: admin user + in-memory S3 + scanner |
| 35 |
- `with_synckit_storage()`: SyncKit in-memory bucket (OTA tests) |
| 36 |
- `with_creator_tier_checkout()`: mock Stripe + a configured Everything-tier price |
| 37 |
- `with_postmark()`: Postmark webhook tokens configured |
| 38 |
|
| 39 |
Anything not covered by a constructor goes through `TestHarness::build(BuildOptions { .. })` |
| 40 |
directly; add a documented `BuildOptions` field rather than a constructor per calling test. |
| 41 |
|
| 42 |
**Seeding:** `harness/seed.rs` provides `seed_user` and `seed_project` for the |
| 43 |
`db_*_layer.rs` contract tests, which run against a bare `TestDb` with no router |
| 44 |
and so cannot use `signup`. Prefer the harness methods (`signup`, `create_creator`, |
| 45 |
`create_creator_with_item`) anywhere a session or HTTP flow is in play. |
| 46 |
|
| 47 |
### Seal Tests |
| 48 |
|
| 49 |
Ratchets over the repo itself, each its own binary. No database. |
| 50 |
|
| 51 |
- `assumptions.rs` — the business assumptions TOML parses, validates, and still resolves every marker in the site-docs corpus. |
| 52 |
- `migration_hygiene.rs` — new migrations use `CONCURRENTLY` / `IF NOT EXISTS` and opt out of the per-migration transaction correctly. |
| 53 |
- `frontend_globals.rs` — the `window.*` global count only goes down. |
| 54 |
- `test_hygiene.rs` — test-suite conventions: doc headers, `#[ignore]` reasons, and `HIGH_WATER` counts for loose status assertions, `test_` prefixes, and oversized modules. |
| 55 |
- `workflows/enum_drift.rs` — every domain enum's variants match its Postgres `CHECK` list (needs a DB; runs inside the integration binary). |
| 56 |
|
| 57 |
### Load Tests (`cargo test --test load -- --ignored --nocapture`) |
| 58 |
|
| 59 |
Multi-scenario virtual user simulation. Requires `--ignored` flag. Configurable via env vars: |
| 60 |
- `LOAD_VUS`: virtual users (default: 20) |
| 61 |
- `LOAD_DURATION_SECS`: duration (default: 30) |
| 62 |
- `LOAD_RAMP_SECS`: ramp-up (default: 5) |
| 63 |
|
| 64 |
### Health Tests (`cargo test --test health`) |
| 65 |
|
| 66 |
External HTTP tests against a running server at `http://localhost:3000`. Skips gracefully if server is not running. |
| 67 |
|
| 68 |
