+
+## Task Results
+
+| Task | Status | Files Modified | Tests | AC Coverage | Issues |
+|------|--------|----------------|-------|-------------|--------|
+| AZ-285_test_infrastructure | Done | 4 files | 4/4 pass | AC-1 ✓, AC-3 ✓, AC-2 deferred to Step 7 | 2 Low (1 deferred AC, 1 pre-existing license note) |
+
+## Files Changed
+
+- `SatelliteProvider.Tests/SatelliteProvider.Tests.csproj` — add DataAccess project reference
+- `SatelliteProvider.Tests/Fixtures/TestCoordinates.cs` — new shared test data (REG-01..REG-03, ROUTE-01/04/06)
+- `SatelliteProvider.Tests/InfrastructureTests.cs` — new (replaces deleted GoogleMapsDownloaderTests.cs)
+- `SatelliteProvider.Tests/GoogleMapsDownloaderTests.cs` — deleted (was misnamed dummy test)
+
+## AC Test Coverage: All covered (AC-2 deferred — environment-level)
+
+- AC-1 (project builds, mocks resolve) → `AllMockableInterfaces_CanBeMocked`, `TileService_ConstructsWithMockedDependencies`
+- AC-2 (docker-compose tests succeed) → out-of-batch; verified in Step 7 (Run Tests) via `scripts/run-tests.sh`
+- AC-3 (test runner discovers + executes test classes) → satisfied by passing `dotnet test` run (4 discovered, 4 passed)
+
