Iciclecreek.Azure.Storage.Memory

A thread-safe, in-memory drop-in replacement for Azure.Storage.Blobs, Azure.Data.Tables, and Azure.Storage.Queues clients. Use the same Azure SDK types in tests without any disk I/O, databases, or external services.

Objects returned from reads are deep-cloned to properly simulate network storage semantics -- no shared references, no accidental cache hits.

Installation

dotnet add package Iciclecreek.Azure.Storage.Memory

Usage

Blobs

using Iciclecreek.Azure.Storage.Memory.Blobs;

var blobService = new MemoryBlobServiceClient();
BlobContainerClient container = blobService.GetBlobContainerClient("my-container");
await container.CreateIfNotExistsAsync();

BlobClient blob = container.GetBlobClient("hello.txt");
await blob.UploadAsync(BinaryData.FromString("Hello, World!"));

var result = (await blob.DownloadContentAsync()).Value;
Console.WriteLine(result.Content.ToString()); // "Hello, World!"

Tables

using Iciclecreek.Azure.Storage.Memory.Tables;

var tableService = new MemoryTableServiceClient();
TableClient table = tableService.GetTableClient("people");
await table.CreateIfNotExistsAsync();

await table.AddEntityAsync(new TableEntity("users", "alice") { ["Name"] = "Alice" });
var entity = (await table.GetEntityAsync<TableEntity>("users", "alice")).Value;

Queues

using Iciclecreek.Azure.Storage.Memory.Queues;

var queueService = new MemoryQueueServiceClient();
QueueClient queue = queueService.GetQueueClient("tasks");
queue.Create();

queue.SendMessage("do the thing");
var msg = queue.ReceiveMessage().Value;
Console.WriteLine(msg.Body.ToString()); // "do the thing"

Swap in via dependency injection

Every Memory* client inherits from its Azure SDK base type:

// Production
services.AddSingleton<BlobServiceClient>(
 new BlobServiceClient(connectionString));

// Test
services.AddSingleton<BlobServiceClient>(
 new MemoryBlobServiceClient());
