# 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: `NewUniqueConstraintIncludesSourceColumn_AZ484_AC1`, `BackfillUpdateAssignsGoogleMapsAndCapturedAt_AZ484_AC4`, `MultiSourceInsertCoexistsUnderNewIndex_AZ484_AC1`, `MostRecentAcrossSourcesSelection_AZ484_AC2`, `SameSourceUpsertReplacesPreviousRow_AZ484_AC3` (latter four use temp tables to keep production data untouched).
- `JwtIntegrationTests` (added by AZ-487, cycle 2; helpers consolidated by AZ-491 cycle 3) — `AnonymousRequest_To_AnyEndpoint_Returns401`, `ExpiredToken_Returns401`, `InvalidSignature_Returns401`, `ValidToken_Returns200_OnHealthyEndpoint`, `SwaggerDocument_AdvertisesBearerSecurityScheme`. HS256 token minting lives in the shared `SatelliteProvider.TestSupport.JwtTokenFactory` (consumed via `ProjectReference`); runner-specific concerns (`JwtTestHelpers.ResolveSecretOrThrow`, `AttachDefaultAuthorization`, `DefaultSubject = "integration-tests"`) remain in this project. The test runner sets `JWT_SECRET` on the API container and attaches a Bearer token to every existing test's HTTP requests so the pre-cycle-2 suite continues to pass.
- `UavUploadTests` (added by AZ-488, cycle 2) — `HappyPathSingleItem_PersistsRow`, `MixedBatch_ReturnsPerItemResults`, `MultiSourceCoexistence_AZ484_Cycle2`, `SameSourceUpsert_AZ484_Cycle2`, `NoToken_Returns401`, `ValidTokenWithoutGpsPermission_Returns403`, `OversizedBatch_Returns400`. Uses a wall-clock-seeded coordinate counter (`_coordinateCounter` initialized from `DateTime.UtcNow`) so each docker-compose run picks a fresh coordinate band — the postgres named volume persists across runs and a naïve `int = 0` counter collided with prior runs on the per-source unique index (fixed mid-Step-11).
- `StubAndErrorContractTests` (existing) — updated in cycle 2 to drop the legacy `StubUpload_Returns501` expectation since AZ-488 implemented the endpoint.

### 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

## 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
- No project references (standalone console app)
- Communicates with the API exclusively via HTTP
- NuGet: implicit .NET 8 runtime

## 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`)

## 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.
