[QUERY] - How do I mock an IPage<DeploymentOperation> for my unit tests

Query/Question I saw this blog post which provides an example of making a Page using the .FromValues method but with the Azure Resource Manager SDK, I don’t see this exposed as an option when trying to mock a DeploymentOperations object.

We are specifically trying to setup a moq for this method:

ResourceManagerClient.DeploymentOperations.ListAtScopeWithHttpMessagesAsync

This method returns an object of type

Task<AzureOperationResponse<IPage<DeploymentOperation>>>

We have tried a number of things and been unable to create a Mock object of this type for unit testing. How do we convert our test response object into a Paged version? Note: making an AzureOperationResponce isn’t too hard, it’s the Page/IPage that is giving us grief.

var operationProperties = new DeploymentOperationProperties(
                provisioningOperation: ProvisioningOperation.Create,
                provisioningState:"complete",
                DateTime.UtcNow,
                duration:"2 minutes", 
                serviceRequestId:null, 
                statusCode: "OK", 
                statusMessage: new StatusMessage("OK"));

            var myOperation = new DeploymentOperation(
                id:"someid123", operationId:"hello",
                properties: operationProperties);

            var l = myOperation as Page<DeploymentOperation>;

This gives an error of:

Cannot convert type ‘Microsoft.Azure.Management.ResourceManager.Models.DeploymentOperation’ to ‘Microsoft.Azure.Management.ResourceManager.Models.Page<Microsoft.Azure.Management.ResourceManager.Models.DeploymentOperation>’ via a reference conversion, boxing conversion, unboxing conversion, wrapping conversion, or null type conversion

Documentation for this shows people using Page<T>.FromValues which we do not see as available.

Environment:

• Name and version of the Library package used:
  Microsoft.Azure.Management.ResourceManager. 3.13.1-preview
• Hosting platform or OS and .NET runtime version (dotnet --info output for .NET Core projects): [e.g. Azure AppService or Windows 10 .NET Framework 4.8]
• IDE and version : [e.g. Visual Studio 16.3]

The easiest might be to compy one of the existing page models that implement IPage and use it in tests:

https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/redis/Microsoft.Azure.Management.Redis/src/Generated/Models/Page.cs

var operationProperties = new DeploymentOperationProperties(
                provisioningOperation: ProvisioningOperation.Create,
                provisioningState:"complete",
                DateTime.UtcNow,
                duration:"2 minutes", 
                serviceRequestId:null, 
                statusCode: "OK", 
                statusMessage: new StatusMessage("OK"));

            var myOperation = new DeploymentOperation(
                id:"someid123", operationId:"hello",
                properties: operationProperties);
var page = new Page<DeploymentOperation>()
{
    Items = new List<DeploymentOperation>()
	{
		{  myOperation  }
	}
}
