Add test project to MVC with Entity Framework

My project is C# MVC5 with Entity Freamework 6.

I have added a test project to the solution.

The first test is just a simple sanity check to ensure all is connected etc, so it just instantiates a class which calls a stored procedure in the constructor.

However I'm having problems because the test project doesn't have an app.config file and EF wants this for the connection details etc.

I appreciate that the client project is the one whose config is used, but this kind of destroys part of the reason for testing as I also want to ensure that the configuration is correct.

Surely there is a way to tell the subject project to use its own config?

Unit test code:

using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using MyNamespace.Classes;

namespace MyNamespace_Tests
{
    [TestClass]
    public class MyTests
    {
        [TestMethod]
        public void Test1()
        {
            var test = new MyClass(1, 2010, 2, 80000, 25000, 48);
            var a = test.Text1;
            var b = test.Text2;
            Assert.IsTrue(true); // not actually doing a useful test yet               
        }
    }
}

Error is:

System.InvalidOperationException: No connection string named 'Entities' could be found in the application config file.
