Unit Testing Role Providers in ASP.NET 2.0
published on 6/5/2008 7:51:45 AM

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>

    <roleManager enabled="true" defaultProvider="VirtualRoomRoleProvider" cacheRolesInCookie="true"

                  cookieName="VirtualRoomCookie">

      <providers>

        <add name="VirtualRoomRoleProvider" type="System.Web.Security.SqlRoleProvider"

              connectionStringName="VirtualRoomConnectionString" applicationName="VirtualRoom"/>

      </providers>

     

    </roleManager>

    <membership defaultProvider="VirtualRoomProvider">

      <providers>

        <remove name="AspNetSqlMembershipProvider"/>

        <add applicationName="VirtualRoom" requiresQuestionAndAnswer="false"

          requiresUniqueEmail="true" minRequiredNonalphanumericCharacters="0"

          enablePasswordReset="true" passwordFormat="Hashed" connectionStringName="VirtualRoomConnectionString"

          name="VirtualRoomProvider" type="DomainObjects.Providers.VirtualRoomProvider,DomainObjects" />

      </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.
