Unit Testing Role Providers in ASP.NET

Some time back I blogged about unit testing Membership Provider "Membership Provider and Unit Testing" as it turned out I was missing the unit tests for Role Provider. In this post I will explain how to unit test the Role Provider.

First of all here is the implementation of the role provider.

public class VirtualRoomRoleProvider : SqlRoleProvider
{
private NameValueCollection _roleConfig = new NameValueCollection();

        public VirtualRoomRoleProvider()
        {
            _roleConfig.Add("applicationName", "VirtualRoom");
            _roleConfig.Add("connectionStringName", "VirtualRoomConnectionString");
            this.Initialize("VirtualRoomRoleProvider", _roleConfig);

        }
    }

Inside the constructor I am initializing the RoleProvider.

Now, here is the App.config which is inside the TestSuite class library.

<system.web>

</providers>
</membership>
</system.web>

And finally here are the tests.

[TestFixture]
    public class when_a_user_is_assigned_a_role : BaseTest
    {
        [Test]
        public void should_be_able_to_initialize_role_provider()
        {
            VirtualRoomRoleProvider roleProvider = new VirtualRoomRoleProvider();

            Assert.AreEqual("VirtualRoom", roleProvider.ApplicationName);
            Assert.AreEqual("VirtualRoomRoleProvider", roleProvider.Name);
        }

        [Test]
        public void should_verify_that_the_roles_exists()
        {
            Assert.IsTrue(_roleProvider.GetAllRoles().Count() > 0,"No roles exists");
        }

        [Test]
        [RollBack]
        public void should_assign_the_student_role_to_the_new_user()
        {
            MembershipUser user = _provider.CreateUser(_username, _password, _email, null, null, true, null, out _status);

Assert.IsTrue(_roleProvider.IsUserInRole(user.UserName, "Student"),"User is not a student!");
}
}

The BaseTest class does all the work to initialize the variables.

[TestFixture]
    public class BaseTest
    {
        protected string _username;
        protected string _password;
        protected string _email;
        protected VirtualRoomProvider _provider;
        protected NameValueCollection _config;
        protected MembershipCreateStatus _status = new MembershipCreateStatus();
        protected SqlRoleProvider _roleProvider;
        protected NameValueCollection _roleConfig;

        [SetUp]
        public void initialize()
        {
            _username = "mary";
            _password = "marykate$";
            _email = "marykate@gmail.com";

// setup the membership provider
_provider = new VirtualRoomProvider();

            _config = new NameValueCollection();
            _config.Add("applicationName", "VirtualRoom");
            _config.Add("name", "VirtualRoomProvider");
            _config.Add("requiresQuestionAndAnswer", "false");
            _config.Add("connectionStringName", "VirtualRoomConnectionString");
            _provider.Initialize(_config["name"], _config);

_status = new MembershipCreateStatus();

            _roleProvider = new SqlRoleProvider();
            // setup the role provider
            _roleConfig = new NameValueCollection();
            _roleConfig.Add("applicationName", "VirtualRoom");
           // _roleConfig.Add("name", "VirtualRoomRoleProvider");
            _roleConfig.Add("connectionStringName", "VirtualRoomConnectionString");
            _roleProvider.Initialize("VirtualRoomRoleProvider", _roleConfig);

            Console.WriteLine("Setup is fired");
        }
    }

The BaseTest class allows me to use reuse the variables in other classes and tests.
