Access Sitecore context in Unit test project

I would like to access sitecore context in MS Test Project. I am using Sitecore 8.1 and the MS test project (Framework: 4.5.2) using VS 2005 I followed some of the instructions found here http://getfishtank.ca/blog/unit-testing-in-sitecore-with-context-and-app-config

So I have all the required DLLS and sitecore config files in my unit test project.

My code is below:

    [TestMethod]
    public void TestMethod1()
    {
        State.HttpRuntime.AppDomainAppPath = Directory.GetCurrentDirectory();

        string dataFolder = Sitecore.Configuration.Settings.DataFolder;
        string licenseFile = Settings.LicenseFile;

        var db = Sitecore.Configuration.Factory.GetDatabase("master");
        var home = db.GetItem("/sitecore/content/");
        Assert.AreEqual(5, 5);
    }

Now I am getting error below:

        Result StackTrace:  
    at System.Reflection.RuntimeAssembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, RuntimeAssembly locationHint, StackCrawlMark& stackMark, IntPtr pPrivHostBinder, Boolean throwOnFileNotFound, Boolean forIntrospection, Boolean suppressSecurityChecks)

Operation is not supported. (Exception from HRESULT: 0x80131515) ---> System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

I have checked the license file path and its correct. I have also added this

 <runtime>
    <loadFromRemoteSources enabled="true"/>
 </runtime>

Can anyone help me ?

In order to unit test using Sitecore.Context, you will need to copy all Sitecore configs from the App_Config into your unit testing project as well as copying across the web.config and renaming it to app.config. You can find a more detailed walkthrough here: http://getfishtank.ca/blog/unit-testing-in-sitecore-with-context-and-app-config

I would however suggest you use Sitecore FakeDb to run your unit tests. This will allow you to isolate your test better without reliance on a running Sitecore instance/database and allowing for more controlled tests to be executed since the data will not be constantly changing due to updates.
