may help you . It is not the case that it will pick it up from your Web application by default.
It will be looking for it in the current project where it is running.
public class RoleController : Controller
      private IRoleRepository roleRepository;

      // This constructor would not be needed if you were to use IOC container
      public RoleController ()
         this.roleRepository = new RoleRepository(new RoleContext());

      public RoleController(IRoleRepository studentRepository)
         this.roleRepository = roleRepository;
public class RoleControllerTest
    private Mock<IRoleRepository> _roleRepository;

    public void SetUp()
    _roleRepository = new Mock<IRoleRepository>();


    public void IndexRoleController()
    public void DetailsRoleController()
        RoleController RC = new RoleController(_roleRepository.Object);
        var result = RC.Delete(1);

Can a unit test project load the target application's app.config file?

Tag : chash , By : firebasket

like below fixes the issue The simplest way to do this is to add the .config file in the deployment section on your unit test.
To do so, open the .testrunconfig file from your Solution Items. In the Deployment section, add the output .config files from your project's build directory (presumably bin\Debug).

appharbor test project app.config file does not change its connectionstring

I hope this helps . The connectionstring is only inserted when your code is deployed. In general, you shouldn't hit your database or do other external I/O during unit testing.

No connectionstring named '' could be found in the application config file

this one helps. I've found a simple solution for that. You have to remove "name=" from the parameter string when you call entities constructor's base constructor. So you have to change this:
public partial class SalesContext : DbContext 
    public SalesContext() 
        : base("name=SalesContext") 
public partial  class SalesContext : DbContext 
    public SalesContext() 
        : base("SalesContext")

Unit Test Project: "No connection string could be found in the application config file"

To fix this issue When you are executing a unittest, that project is your running application. So that is where the configuration file is read from. And note that you need an app.config, not a web.config.
