# Module: Tests/SatelliteProvider.IntegrationTests ## Purpose Console application that runs end-to-end integration tests against a live API instance. Designed to run in Docker alongside the API and PostgreSQL containers. ## Public Interface ### Test Classes - `TileTests` — tile download via lat/lon endpoint - `RegionTests` — region request → polling → completion flow - `BasicRouteTests` — route creation with intermediate points - `ComplexRouteTests` — routes with geofencing - `ExtendedRouteTests` — routes with `requestMaps: true` and tile ZIP creation - `MigrationTests` — direct PostgreSQL schema/index validation (no HTTP). AZ-484 cycle added: `BackfillUpdateAssignsGoogleMapsAndCapturedAt_AZ484_AC4`, `MultiSourceInsertCoexistsUnderNewIndex_AZ484_AC1`, `MostRecentAcrossSourcesSelection_AZ484_AC2`, `SameSourceUpsertReplacesPreviousRow_AZ484_AC3` (latter four use temp tables to keep production data untouched). AZ-503 (cycle 5) added: `Az503ColumnsExistAndLocationHashIsNotNull` (asserts the 4 new columns + `location_hash NOT NULL`), `Az503NewUniqueIndexCoversIntegerKeyAndFlightId` (asserts `idx_tiles_unique_identity` columns + `COALESCE(flight_id, ...)` predicate), `Az503LocationHashBackfillIsDeterministic` (computes `pg_temp.uuidv5("18/12345/23456")` and compares byte-for-byte against the C# `Uuidv5.Create` output on 3 sampled live rows); the AZ-484 supersession test was renamed to `Az503MigrationSupersedesAz484UniqueIndex` and asserts `idx_tiles_unique_location_source` no longer exists. - `JwtIntegrationTests` (added by AZ-487 cycle 2; helpers consolidated by AZ-491 cycle 3; iss/aud scenarios added by AZ-494 cycle 3) — `AnonymousRequest_To_AnyEndpoint_Returns401`, `ExpiredToken_Returns401`, `InvalidSignature_Returns401`, `ValidToken_Returns200_OnHealthyEndpoint`, `WrongIssuer_Returns401` (AZ-494 AC-1), `WrongAudience_Returns401` (AZ-494 AC-2), `SwaggerDocument_AdvertisesBearerSecurityScheme`. HS256 token minting lives in the shared `SatelliteProvider.TestSupport.JwtTokenFactory` (consumed via `ProjectReference`); runner-specific concerns (`JwtTestHelpers.ResolveSecretOrThrow` / `ResolveIssuerOrThrow` / `ResolveAudienceOrThrow`, `MintAuthenticated` / `MintExpired` convenience wrappers that auto-fill iss+aud from env, `AttachDefaultAuthorization`, `DefaultSubject = "integration-tests"`) remain in this project. The test runner sets `JWT_SECRET` + `JWT_ISSUER` + `JWT_AUDIENCE` on the API container and attaches a Bearer token (with matching iss/aud) to every existing test's HTTP requests so the pre-cycle-2 suite continues to pass. - `UavUploadTests` (added by AZ-488, cycle 2; coordinate-counter promoted to defense-in-depth by AZ-493 cycle 3; AZ-503 cycle 5 added 2 more tests) — `HappyPathSingleItem_PersistsRow`, `MixedBatch_ReturnsPerItemResults`, `MultiSourceCoexistence_AZ484_Cycle2`, `SameSourceUpsert_AZ484_Cycle2`, `NoToken_Returns401`, `ValidTokenWithoutGpsPermission_Returns403`, `OversizedBatch_Returns400`, plus AZ-503: `MultiFlightUavRowsCoexist_AZ503_AC3` (two flights at the same cell → two rows, one `location_hash`, two `file_path`s under `./tiles/uav/{flight_id}/...`) and `FloatRoundingDoesNotBreakIdempotence_AZ503_AC4` (two uploads with float-distinct `latitude` recomputed from `TileToWorldPos` collapse to a single row because the conflict key is integer-only). The AZ-503 migration made `location_hash NOT NULL`, so the cycle-2 `MultiSourceCoexistence_AZ484_Cycle2` seeder was updated to compute `location_hash` via `Uuidv5.Create` (canonical name `"{zoom}/0/0"`) before the raw SQL `INSERT` — this required adding a `ProjectReference` from `SatelliteProvider.IntegrationTests` to `SatelliteProvider.Common`. The wall-clock-seeded `_coordinateCounter` is retained as a belt-and-suspenders safeguard alongside the AZ-493 startup DB-reset (below) — if a developer runs with `--keep-state`, or the DB-reset path is skipped for any reason, the wall-clock seed still spreads coordinates across runs so the unique index does not collide. - `StubAndErrorContractTests` (existing) — updated in cycle 2 to drop the legacy `StubUpload_Returns501` expectation since AZ-488 implemented the endpoint. - `TileInventoryTests` (added cycle 6 — AZ-505) — `OrderingAndPresentAbsentShaping_AC1`, `LeafletReadReturnsMostRecentViaLocationHash_AC2`, `ValidationRejectsBothPopulated_AC6`, `ValidationRejectsNeitherPopulated_AC6`, `ValidationRejectsOversizedBatch_AC6`, `UnauthenticatedRequestReturns401_AC6`, `PerformanceBudget_AC4` (full-suite only). Tests are cycle-7-stable — they use the post-AZ-794 `{z, x, y}` wire shape and a minor x/y reduction was applied in cycle 7 to keep the synthetic coords within the z=18 slippy bounds enforced by `TileCoordValidator`. - `TileInventoryValidationTests` (added cycle 7 — AZ-796) — 16 tests: `HappyPath_Returns200`, `EmptyBody_Returns400`, `NeitherPopulated_Returns400`, `BothPopulated_Returns400`, `EmptyTilesArray_Returns400`, `TilesOverCap_Returns400`, `MissingZ_Returns400WithFieldPath`, `MissingXAndY_Returns400`, `ZoomOutOfRange_Returns400WithFieldPath`, `XBeyondZoomBounds_Returns400`, `YBeyondZoomBounds_Returns400`, `NegativeAxis_Returns400`, `UnknownRootField_Returns400`, `UnknownNestedField_Returns400`, `OldV1FieldName_Returns400` (AZ-794 + AZ-796 intersection — exact AZ-777 Phase 1 reproducer body, asserts legacy `tileZoom/tileX/tileY` now yields 400), `TypeMismatch_Returns400`. Each test exercises one of the 9 validation rules end-to-end through `ValidationEndpointFilter` + `GlobalExceptionHandler`, asserts HTTP 400 + RFC 7807 `ValidationProblemDetails` shape via the shared `ProblemDetailsAssertions` helper. - `IdempotentPostTests` — pre-existing; cycle 7 adjusted the route-point payload from PascalCase (`Latitude`/`Longitude`) to camelCase (`lat`/`lon`) because the post-AZ-795 `UnmappedMemberHandling.Disallow` would otherwise reject the previously-silently-ignored fields. The `RoutePoint` DTO has carried `JsonPropertyName("lat"/"lon")` since AZ-309; cycle 7's strict JSON parsing exposed the test was sending the wrong shape and getting away with it via the pre-cycle-7 permissive deserializer. ### Supporting Classes - `Models.cs` — HTTP response DTOs for deserialization - `RouteTestHelpers.cs` — shared utilities (wait-for-completion polling, geofence polygon builders, test data) - `Program.cs` — test runner entry point (handles `--smoke` / `--full` mode selection, `--keep-state` opt-out flag, default-token issuance via `JwtTokenFactory`, the AZ-493 DB-reset hook, and the AZ-492 `--mint-only` / `--gen-uav-fixture` perf-bootstrap subcommands that short-circuit before any HTTP / DB setup) - `JwtTestHelpers.cs` — runner-side JWT concerns: - `ResolveSecretOrThrow` reads `JWT_SECRET` env var with size validation - `ResolveIssuerOrThrow` / `ResolveAudienceOrThrow` (AZ-494) read `JWT_ISSUER` / `JWT_AUDIENCE` with fail-fast contract - `MintAuthenticated(secret, …)` (AZ-494) auto-fills iss/aud from env and delegates to `JwtTokenFactory.Create`; accepts `overrideIssuer` / `overrideAudience` for negative-AC scenarios (`WrongIssuer_Returns401` / `WrongAudience_Returns401`) - `MintExpired(secret, …)` (AZ-494) mirrors `MintAuthenticated` for the expired-token fixture - `AttachDefaultAuthorization` puts a Bearer token on the shared `HttpClient` - `DefaultSubject = "integration-tests"` is the canonical runner subject value - Token *minting* lives in the shared `SatelliteProvider.TestSupport.JwtTokenFactory` (AZ-491) — runner-side concerns (env reads, HttpClient mutation, the iss/aud-aware mint wrapper) deliberately stay here. - `IntegrationTestDatabaseReset.cs` (AZ-493) — instance class with a single `EnsureCleanStateAsync()` method that truncates the integration-test target tables in FK-safe order. Guarded via `SatelliteProvider.TestSupport.IntegrationTestResetGuard` (env + Host allowlist) so it cannot run against a non-test database. - `PerfBootstrap.cs` (AZ-492) — static helpers for the perf harness bootstrap subcommands. `MintToken()` mints a 4-hour HS256 token with subject `perf-tests` and a `permissions: GPS` claim via the canonical `SatelliteProvider.TestSupport.JwtTokenFactory.Create`; `GenerateUavFixture(args)` writes a 256×256 random-noise JPEG via `SixLabors.ImageSharp` to the path passed on the CLI. Invoked from `scripts/run-performance-tests.sh` via `dotnet --mint-only` and `--gen-uav-fixture `. - `ProblemDetailsAssertions.cs` (added cycle 7 — AZ-795) — shared static helpers for asserting RFC 7807 ProblemDetails bodies on integration-test responses. `ReadProblemDetailsAsync(HttpResponseMessage, label)` deserialises the response body into a `JsonElement` with helpful failure messages when the content-type / shape doesn't match. `AssertProblemDetails(problem, expectedStatus, label)` asserts the base ProblemDetails shape (`type`, `title`, `status`). `AssertValidationProblem(problem, expectedStatus, label, expectedErrorPath?, expectedErrorContains?)` extends the base assertion to require the `errors` map per `error-shape.md` Inv-2 and optionally checks a specific field path / message substring. Consumed by `TileInventoryValidationTests`; designed to be reused by every future per-endpoint child task under AZ-795. ## Internal Logic - Makes HTTP calls to the API at `API_URL` environment variable (default: `http://api:8080`) - Tests are methods called sequentially from `Program.cs` (not xUnit — plain console app) - Poll-based waiting for async operations (region/route completion) - Validates response structure, status transitions, file creation ## Dependencies - `ProjectReference` to `SatelliteProvider.TestSupport` (added by AZ-491; provides `JwtTokenFactory`. Added by AZ-493; provides `IntegrationTestResetGuard`). - Communicates with the API exclusively via HTTP for end-to-end tests; communicates with PostgreSQL directly only via the dedicated DB-reset hook + the existing `MigrationTests` schema assertions. - NuGet: `Npgsql` 9.0.2 (Postgres client for DB-reset + MigrationTests), `SixLabors.ImageSharp` 3.1.11 (UAV fixture image generation). - ProjectReferences: `SatelliteProvider.Api` (running service for the integration runner), `SatelliteProvider.TestSupport` (canonical `JwtTokenFactory` + `IntegrationTestResetGuard`), `SatelliteProvider.Common` (added by AZ-503 so the `MultiSourceCoexistence_AZ484_Cycle2` seeder can compute `location_hash` via `Uuidv5.Create` instead of duplicating the UUIDv5 algorithm in T-SQL fixtures). ## Consumers - `docker-compose.tests.yml` — runs as a container that depends on the API service ## Configuration - `API_URL` environment variable (set in docker-compose.tests.yml to `http://api:8080`) - `INTEGRATION_TESTS_MODE` — `smoke` or `full` (default `full`). Drives `TestRunMode.Smoke`. - `INTEGRATION_KEEP_STATE` — set to `1` or `true` (or pass `--keep-state` to `Program.cs` / `scripts/run-tests.sh`) to skip the AZ-493 DB-reset hook. Useful for debugging a failed run. - `ASPNETCORE_ENVIRONMENT=Testing` — guard for the DB-reset hook. The reset refuses to run unless this is set (see Reliability § Test isolation below). - `JWT_SECRET` — shared HMAC secret with the API container; must be ≥ 32 bytes (UTF-8). - `JWT_ISSUER` — expected `iss` claim, must match the API container (AZ-494). Fail-fast at startup if unset. - `JWT_AUDIENCE` — expected `aud` claim, must match the API container (AZ-494). Fail-fast at startup if unset. - `DB_CONNECTION_STRING` — Npgsql connection string; the reset hook additionally requires the Host to be in the allowed-host list (`postgres`, `localhost`, `127.0.0.1`). ## Reliability ### Test isolation (AZ-493) `Program.cs` runs `IntegrationTestDatabaseReset.EnsureCleanStateAsync()` at startup, before any test class executes. The hook truncates `route_regions`, `route_points`, `routes`, `regions`, `tiles` (in that FK-safe order, with `RESTART IDENTITY CASCADE`) so each run starts from a known empty state. The Postgres named volume in `docker-compose.yml` is intentionally persisted across `docker-compose down` cycles for fast iteration; the AZ-493 reset hook is what gives back per-run isolation in spite of that. Two guards protect against accidental truncate against a non-test database: 1. `ASPNETCORE_ENVIRONMENT` MUST equal `Testing` (case-insensitive). Set by `docker-compose.tests.yml`; absent in production / dev. 2. `DB_CONNECTION_STRING` Host MUST be one of `postgres`, `localhost`, `127.0.0.1`. Set by `docker-compose.tests.yml` and developer machines; a remote-host connection string is rejected even with the env guard satisfied. Both guards are pure-string checks in `SatelliteProvider.TestSupport.IntegrationTestResetGuard` — unit-tested in `SatelliteProvider.Tests/TestSupport/IntegrationTestResetGuardTests.cs`. Failure of either guard surfaces a clear `InvalidOperationException` and exits the runner with code 1. To debug leftover state from a failed run, opt out of the reset: - CLI: `./scripts/run-tests.sh --full --keep-state` - Direct: `INTEGRATION_KEEP_STATE=1 docker compose ... up` - In the runner Main: `dotnet run --project SatelliteProvider.IntegrationTests -- --keep-state` ### Adding new tables If a new task adds a table that integration tests insert into AND that table participates in foreign-key relationships with `tiles` / `regions` / `routes`, update `IntegrationTestDatabaseReset.TruncateOrder` to include the new table in FK-safe order. The current order assumes the AZ-484 + AZ-488 schema; future migrations that introduce new FK chains need a corresponding order revision. The `CASCADE` clause is a safety net but is not a substitute for an explicit order — the order is the audit trail for "what does an integration-test runner see at startup". ## External Integrations - HTTP to the SatelliteProvider API - Reads output files from mounted `./ready/` and `./tiles/` volumes ## Security None. ## Tests This IS the integration test suite.
