This project is read-only.


WFTestDesign is based upon and modeled after BizUnit, the most popular unit-testing and acceptance-testing framework for BizTalk Server.

While BizUnit allows you to author test cases using XML files - or XAML in v4.0 - it cannot natively host and execute the generated tests. This confines its use to developers who need to write custom code or use any third-party unit-testing framework such as NUnit or MsTest.

Instead, WFTestDesign uses Windows Workflow Foundation 4.0 both for authoring and executing test cases. It's intuitive user interface leverages WF's graphical design surface to author test cases in which each step is available as a dedicated Workflow Activity. The execution engine hosts and runs the compiled test cases.

WFTestDesign depends upon Windows WorkFlow Foundation 4.0 and runs inside Visual Studio 2010.

Getting Started

After installing the framework, you will find a new project template:

When the project is created, you can find the following files:

Content of the project

Content of the WFTestDesignTestLauncher.cs

using System;
using System.Text;
using System.Collections.Generic;
using System.Linq;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using WFTestDesign;

namespace WFTestDesignTestProject1
    public class WFTestDesignTest1
        public void TestMethod1()
            WFTestDesignInvoker wFTest = new WFTestDesignInvoker(@"C:\MyProjects\TestProject1\WFTestDesignTestProject1\WFTestDesignUnitTest1.xaml");

and a TestCase with the WFTestDesignUnitTest1.xaml (a simple workflow activity file)

Empty test case UI

Now you can drag and drop the Workflow Activity and design a new test:


The following activities are available:


I will try to upload a screencast as soon as possible to explain a quick start in video
