Microsoft Fakes and LINQ (Custom Workflow Activity) in CRM

Hi,

Just sharing a sample code to test a custom workflow activity using Microsoft Fakes.

The custom workflow activity uses LINQ.

The custom workflow activity code

public sealed class MyCustomWorkflowActivity : CodeActivity
{
#region Public Properties

[Input("Stage Name")]
public InArgument<string> StageName { get; set; }

#endregion

#region Methods

/// <summary>
/// Executes the workflow activity.
/// </summary>
/// <param name="executionContext">
/// The execution context.
/// </param>
protected override void Execute(CodeActivityContext executionContext)
{
// Create the tracing service
var tracingService = executionContext.GetExtension<ITracingService>();

// Create the context
var context = executionContext.GetExtension<IWorkflowContext>();

var serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();

IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

try
{
using (var xrmServiceContext = new XrmServiceContext(service))
{
// get the business process workflow id
var workflow = (from w in xrmServiceContext.WorkflowSet
where w.Name == "Business Process Workflow Name"
select new Workflow { WorkflowId = w.WorkflowId }).FirstOrDefault();

if (workflow != null)
{
// get the stage name from the context's input parameter
