Microsoft Azure Load Testing management client library for .NET

Artikel
11/30/2023

Microsoft Azure Load Testing is a fully managed load-testing service that enables you to generate high-scale load. The service simulates traffic for your applications, regardless of where they're hosted. Developers, testers, and quality assurance (QA) engineers can use it to optimize application performance, scalability, or capacity.

This library supports managing Microsoft Azure Load Testing resources.

This library follows the new Azure SDK guidelines, and provides many core capabilities:

- Support MSAL.NET, Azure.Identity is out of box for supporting MSAL.NET.
- Support [OpenTelemetry](https://opentelemetry.io/) for distributed tracing.
- HTTP pipeline with custom policies.
- Better error-handling.
- Support uniform telemetry across all languages.

Examples

Create a new Azure Load Testing resource

Before creating an Azure Load Testing resource, we need to have a resource group.

ArmClient armClient = new ArmClient(new DefaultAzureCredential());
SubscriptionResource subscription = await armClient.GetDefaultSubscriptionAsync();
ResourceGroupCollection rgCollection = subscription.GetResourceGroups();
// With the collection, we can create a new resource group with an specific name
string rgName = "sample-rg";
AzureLocation location = AzureLocation.WestUS2;
ArmOperation<ResourceGroupResource> resourceGroupLro = await rgCollection.CreateOrUpdateAsync(WaitUntil.Completed, rgName, new ResourceGroupData(location));
ResourceGroupResource resourceGroup = lro.Value;

Create an Azure Load Testing resource.

LoadTestingResourceCollection loadTestingCollection = _resourceGroup.GetLoadTestingResources();
string loadTestResourceName = "sample-loadtest";
LoadTestingResourceData inputPayload = new LoadTestingResourceData(AzureLocation.WestUS2);
ArmOperation<LoadTestingResource> loadTestingLro = await loadTestingCollection.CreateOrUpdateAsync(WaitUntil.Completed, loadTestResourceName, inputPayload);

LoadTestingResource resource = loadTestingLro.Value;

Create an Azure Load Testing resource configured with CMK encryption.

LoadTestingResourceCollection loadTestingCollection = _resourceGroup.GetLoadTestingResources();
string loadTestResourceName = "sample-loadtest";
LoadTestingResourceData inputPayload = new LoadTestingResourceData(AzureLocation.WestUS2);

// Managed identity properties
ResourceIdentifier identityId = new ResourceIdentifier("/subscriptions/00000000-0000-0000-0000-000000000000/resourcegroups/sample-rg/providers/microsoft.managedidentity/userassignedidentities/identity1");
inputPayload.Identity = new ManagedServiceIdentity(ManagedServiceIdentityType.SystemAssignedUserAssigned);
inputPayload.Identity.UserAssignedIdentities.Add(identityId, new UserAssignedIdentity());

// CMK encryption properties
inputPayload.Encryption = new LoadTestingCmkEncryptionProperties();
inputPayload.Encryption.KeyUri = new Uri("https://sample-kv.vault.azure.net/keys/cmkkey/2d1ccd5c50234ea2a0858fe148b69cde");
inputPayload.Encryption.Identity = new LoadTestingCmkIdentity();
inputPayload.Encryption.Identity.IdentityType = LoadTestingCmkIdentityType.UserAssigned;
inputPayload.Encryption.Identity.ResourceId = identityId;

ArmOperation<LoadTestingResource> loadTestingLro = await loadTestingCollection.CreateOrUpdateAsync(WaitUntil.Completed, loadTestResourceName, inputPayload);

LoadTestingResource resource = loadTestingLro.Value;

Get details of an Azure Load Testing resource

LoadTestingResourceCollection loadTestingCollection = _resourceGroup.GetLoadTestingResources();

string loadTestResourceName = "sample-loadtest";
Response<LoadTestingResource> loadTestingResponse = await loadTestingCollection.GetAsync(loadTestResourceName);

LoadTestingResource resource = loadTestingResponse.Value;

Update an Azure Load Testing resource

Update an Azure Load Testing resource to configure CMK encryption using system-assigned managed identity.

LoadTestingResourceCollection loadTestingCollection = _resourceGroup.GetLoadTestingResources();
string loadTestResourceName = "sample-loadtest";
Response<LoadTestingResource> loadTestingResponse = await loadTestingCollection.GetAsync(loadTestResourceName);
LoadTestingResource resource = loadTestingResponse.Value;

ResourceIdentifier identityId = new ResourceIdentifier("/subscriptions/00000000-0000-0000-0000-000000000000/resourcegroups/sample-rg/providers/microsoft.managedidentity/userassignedidentities/identity1");
LoadTestingResourcePatch resourcePatchPayload = new LoadTestingResourcePatch {
    Encryption = new LoadTestingCmkEncryptionProperties
    {
        Identity = new LoadTestingCmkIdentity
        {
            // make sure that system-assigned managed identity is enabled on this resource and the identity has been granted required permissions to access the key.
            IdentityType = LoadTestingCmkIdentityType.SystemAssigned,
            ResourceId = null
        },
        KeyUri = new Uri("https://sample-kv.vault.azure.net/keys/cmkkey/2d1ccd5c50234ea2a0858fe148b69cde")
    }
};

ArmOperation<LoadTestingResource> loadTestingLro = await resource.UpdateAsync(WaitUntil.Completed, resourcePatchPayload);

LoadTestingResource updatedResource = loadTestingLro.Value;

Update an Azure Load Testing resource to update user-assigned managed identities.

LoadTestingResourceCollection loadTestingCollection = _resourceGroup.GetLoadTestingResources();
string loadTestResourceName = "sample-loadtest";
Response<LoadTestingResource> loadTestingResponse = await loadTestingCollection.GetAsync(loadTestResourceName);
LoadTestingResource resource = loadTestingResponse.Value;

ResourceIdentifier identityId1 = new ResourceIdentifier("/subscriptions/00000000-0000-0000-0000-000000000000/resourcegroups/sample-rg/providers/microsoft.managedidentity/userassignedidentities/identity1");
ResourceIdentifier identityId2 = new ResourceIdentifier("/subscriptions/00000000-0000-0000-0000-000000000000/resourcegroups/sample-rg/providers/microsoft.managedidentity/userassignedidentities/identity2");

LoadTestingResourcePatch resourcePatchPayload = new LoadTestingResourcePatch();
resourcePatchPayload.Identity = new ManagedServiceIdentity(ManagedServiceIdentityType.UserAssigned);
// removes user-assigned identity with resourceId <identityId1> (if already assigned to the load testing resource)
resourcePatchPayload.Identity.UserAssignedIdentities.Add(identityId1, null);
resourcePatchPayload.Identity.UserAssignedIdentities.Add(identityId2, new UserAssignedIdentity());

ArmOperation<LoadTestingResource> loadTestingLro = await resource.UpdateAsync(WaitUntil.Completed, resourcePatchPayload);
LoadTestingResource updatedResource = loadTestingLro.Value;

Delete an Azure Load Testing resource

LoadTestingResourceCollection loadTestingCollection = _resourceGroup.GetLoadTestingResources();
string loadTestResourceName = "sample-loadtest";
Response<LoadTestingResource> loadTestingResponse = await loadTestingCollection.GetAsync(loadTestResourceName);
LoadTestingResource resource = loadTestingResponse.Value;

ArmOperation loadTestDeleteResponse = await resource.DeleteAsync(WaitUntil.Completed);

Quota Operations

Get Load Testing quota collection.

LoadTestingQuotaCollection QuotaCollection = _subscription.GetAllLoadTestingQuota(AzureLocation.WestUS2);
// Use the quotaCollection for all the quota operations.

Get quota values for a particular quota bucket.

LoadTestingQuotaCollection QuotaCollection = _subscription.GetAllLoadTestingQuota(AzureLocation.WestUS2);

// Get the quota values for a particular quota bucket
Response<LoadTestingQuotaResource> quotaResponse = await QuotaCollection.GetAsync("maxConcurrentTestRuns");
LoadTestingQuotaResource quotaBucket = quotaResponse.Value;

Get quota values for all quota buckets.

LoadTestingQuotaCollection QuotaCollection = _subscription.GetAllLoadTestingQuota(AzureLocation.WestUS2);

// Get the quota values for a all quota buckets
List<LoadTestingQuotaResource> quotaBuckets = await QuotaCollection.GetAllAsync().ToEnumerableAsync();

Check quota availability.

LoadTestingQuotaCollection QuotaCollection = _subscription.GetAllLoadTestingQuota(AzureLocation.WestUS2);

Response<LoadTestingQuotaResource> quotaResponse = await QuotaCollection.GetAsync("maxConcurrentTestRuns");
LoadTestingQuotaResource quotaResource = quotaResponse.Value;

LoadTestingQuotaBucketDimensions dimensions = new LoadTestingQuotaBucketDimensions("<subscription-id>", AzureLocation.WestUS2);
LoadTestingQuotaBucketContent quotaAvailabilityPayload = new LoadTestingQuotaBucketContent(
    quotaResponse.Value.Data.Id,
    quotaResource.Data.Name,
    quotaResource.Data.ResourceType,
    null,
    quotaResource.Data.Usage,
    quotaResource.Data.Limit,
    50, // new quota value
    dimensions);

Response<LoadTestingQuotaAvailabilityResult> checkAvailabilityResult = await quotaResponse.Value.CheckLoadTestingQuotaAvailabilityAsync(quotaAvailabilityPayload);
// IsAvailable property indicates whether the requested quota is available.
Console.WriteLine(checkAvailabilityResult.Value.IsAvailable);
