Rig.TUnit.Storage.AzureBlob

Azurite-backed Azure Blob Storage fixture with BlobServiceClient and pure-function AzureBlobSasBuilder for SAS query construction.

What this package is

The Rig.TUnit Azure Blob provider. AzureBlobFixture spins mcr.microsoft.com/azure-storage/azurite via Testcontainers and exposes a ready BlobServiceClient. AzureBlobSasBuilder is a pure function that constructs SAS query strings from container/blob/ permission/TTL — no side effects, unit-testable.

When to use it

  • Integration tests for blob storage upload / download / listing.
  • Testing SAS token construction against Azurite.
  • Verifying container lifecycle operations.
  • Not for: production Azure testing — Azurite diverges on CORS, soft-delete, and change feed.

Prerequisites

  • .NET 10 SDK
  • Docker Desktop / Colima (Azurite image ~180 MB)
  • Azure.Storage.Blobs (transitive)

Quick start

using Rig.TUnit.Storage.AzureBlob.Fixtures;

await using var fx = new AzureBlobFixture();
await fx.InitializeAsync();

var container = fx.Client.GetBlobContainerClient("demo");
await container.CreateIfNotExistsAsync();

Options

Property Type Default Description
Image string "mcr.microsoft.com/azure-storage/azurite:latest" Azurite image
StartupTimeoutSeconds int 60 Azurite boot
AccountName string "devstoreaccount1" Azurite default dev account
AccountKey string "Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==" Well-known Azurite key

Fixture + helper APIs

  • Rig.TUnit.Storage.AzureBlob.Fixtures.AzureBlobFixture
  • Rig.TUnit.Storage.AzureBlob.Options.AzureBlobFixtureOptions
  • Rig.TUnit.Storage.AzureBlob.Builder.AzureBlobRigBuilder
  • Rig.TUnit.Storage.AzureBlob.Helpers.AzureBlobSasBuilder

Per-test isolation

Per-test container: test-{IsolationKey:short}. Teardown deletes the container recursively. Blob operations go inside that container so parallel tests cannot collide.

Parallelism + performance

  • First-run pull: ~20 s.
  • Warm startup: ~5 s.
  • Per-test container create + delete: ~50 ms.
  • Per-blob upload/download: ~5–10 ms.
  • Parallelism: 8+ concurrent tests.

Troubleshooting

  • ArgumentException: Invalid storage account name — the connection string must be UseDevelopmentStorage=true or the explicit Azurite format. Don't substitute a real account name.
  • SAS signature mismatch — Azurite uses the well-known dev key by default; AzureBlobSasBuilder reads it from options.

See .

Provider quirks + edge cases

  • Azurite diverges from real Azure on: soft-delete, change feed, CORS pre-flight. Tests relying on these must run against real Azure.
  • SAS timestamps are UTC; building one with local time fails signature validation. AzureBlobSasBuilder always normalises to UTC.
