    Umbraco Unit Testing Problems due to null ApplicationContext / Umbraco Context

    Hi all,

    I am struggling to get Unit Testing working for Umbraco Scenarios that require UmbracoContext . I have ready many post on the topic but am still having issues …………….

    I am basically using the approach detailed at http://blog.aabech.no/archive/the-basics-of-unit-testing-umbraco/ . Unfortunately, the following Line: 

    var routingContext = this.GetRoutingContext("/", -1, umbracoSettings: settings);

    Causes the following exception (full exception below):

    Value cannot be null. Parameter name: applicationContext

    On the following line of “BaseDatabaseFactoryTests.cs” ( from Umbraco.Tests.dll )

      var ctx = new UmbracoContext(
        httpContext,
        ApplicationContext,
        new PublishedCaches(cache, new PublishedMediaCache(ApplicationContext)),
        new WebSecurity(httpContext, ApplicationContext));

    . This same bug is described at https://our.umbraco.org/forum/umbraco-7/using-umbraco-7/60476-unit-testing-creating-an-UmbracoContext-throws-an-exception#comment-205125 and the resolution suggested there was to use NUnit rather than MSTests. So after some work I made the move to NUnit but was disappointed to find that it did not actually salve the problem.

    So here is the code that I am using:

    using log4net;
using NUnit.Framework;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using TeraTastic.Constants;
using TeraTastic.Models.TT_USPSXML;
using TeraTastic.TT_USPSXML_Classes;
using TeraTastic.TT_USPSXML_Classes.AddressValidateRequestNs;
using UCommerce.EntitiesV2;

namespace TeraTastic.TT_UnitTests
{

    [TestFixture]
    public class TTUSPSXMLTests
    {

        private static readonly ILog iMXML_Log = TeraTastic.TT_Classes.TT_Log4NetUtils.TT_Get_IMXML_Logger(typeof(TTUCTests));
        [Test]
        public void TT_USPS_020_ShippingRateRequest()
        {
            iMXML_Log.Info("TT_USPS_010_AddressValidationTest");
            TTUSPSTestHelper tTUSPSTestHelper = new TTUSPSTestHelper();
            tTUSPSTestHelper.TTUSPSTestInit();
            var returnVal = tTUSPSTestHelper.TT_USPS_020_ShippingRateRequest_Helper();
        }
        // ========================================40

    }
}

    And here is the Helper Class that is used by the Test Class above

    namespace TeraTastic.TT_UnitTests
{
    public class TTUSPSTestHelper : BaseRoutingTest    //  <<<<<<<<<<<  Note we inherit from BaseRoutingTest as recommended by blog referenced below
    {
        //  As described at http://blog.aabech.no/archive/the-basics-of-unit-testing-umbraco/ 
        private static IPublishedContent content;
        private static UmbracoContext umbracoContext;
        private static UmbracoHelper umbracoHelper;

        // Note - do not override Constructor (ctor)

        public void TTUSPSTestInit()           {
            content = Mock.Of<IPublishedContent>();
            var settings = SettingsForTests.GenerateMockSettings();

// >>>>>>>>>>>>>>>>>>>>> FOLLOWING LINE CAUSES THE EXCEPTION
            var routingContext = this.GetRoutingContext("/", -1, umbracoSettings: settings);  
//  <<<<<<<<<<<  THIS IS THE LINE THAT CAUSES THE EXCEPTION

            umbracoContext = routingContext.UmbracoContext;
            umbracoHelper = new UmbracoHelper(umbracoContext, content);
        }

        public Money TT_USPS_020_ShippingRateRequest_Helper()
        {

            // TEST DETAILS REMOVED AS IRRELEVANT
        }
    }
}

    FYI I am using:

    • Umbraco version 7.5.10 (assembly: 1.0.6261.14290)

    • UCommerce uCommerce 7.5.0.17040

    • NUnit {3.10.1}

    • NUnit3TestAdapter {3.10.0}

    • Moq {4.1.1309.0919}

    • A complete listing of Nuget installed packages is below (under the listing of the exception)

    • I also added a reference to Umbraco.Tests.dll from a folder that also contains Umbraco.Tests.dll.config and Umbraco.Tests.pdb. I got these files from downloading source for Umbraco version 7.5.10 and rebuilding to create those files.

    Any help or guidance resolving this would be greatly appreciated :-)

    Thanks

    All,

    An Update.... I have just read Lars-Erik's latter blog post at http://blog.aabech.no/archive/the-basics-of-unit-testing-umbraco-just-got-simpler/.

    As a result I have now removed my project reference to Umbraco.Tests.dll and removed that file as well as Umbraco.Tests.dll.config and Umbraco.Tests.pdb from the bin folder.

    I then installed the "Our.Umbraco.Community.Tests" Nuget package (Version 7.5.10 to match my installed version of Umbraco.)

    Unfortunately I am still getting the same error :-(

    Hi Terry,

    I see you are using NUnit 3. If i'm correct, to use the umbraco test helpers you need to "downgrade" to NUnit 2.6. That is the version in Umbraco Core

    And that works for us.

    And just checked a Umbraco 7.5 project we have running with tests

        [TestFixture]
    public abstract class BaseControllerTest : BaseRoutingTest
    {
        protected UmbracoContext UmbracoContext { get; set; }

        protected UmbracoHelper UmbracoHelper { get; set; }

        protected IPublishedContent Content { get; set; }

        protected  RouteData RouteData { get; set; }

        [SetUp]
        public override void Initialize()
        {

            base.Initialize();

            SettingsForTests.ConfigureSettings(SettingsForTests.GenerateMockSettings());

            this.RouteData = new RouteData();
            var routingContext = this.GetRoutingContext(
                "http://localhost",
                -1,
                this.RouteData,
                true,
                UmbracoConfig.For.UmbracoSettings());

            this.UmbracoContext = routingContext.UmbracoContext;

            this.Content = Mock.Of<IPublishedContent>();


            this.UmbracoContext.PublishedContentRequest = new Umbraco.Web.Routing.PublishedContentRequest(
                new Uri("http://localhost"),
                routingContext,
                UmbracoConfig.For.UmbracoSettings().WebRouting,

            /
            var routeDefinition = new RouteDefinition
            {
                PublishedContentRequest = this.UmbracoContext.PublishedContentRequest
            };

                       this.RouteData.DataTokens.Add(Constants.Web.UmbracoRouteDefinitionDataToken, routeDefinition);

              this.UmbracoHelper = new UmbracoHelper(
                this.UmbracoContext,
                this.Content,
                Mock.Of<ITypedPublishedContentQuery>(),
                Mock.Of<IDynamicPublishedContentQuery>(),
                Mock.Of<ITagQuery>(),
                this.ApplicationContext.Services.DataTypeService,
                this.UmbracoContext.UrlProvider,
                new Mock<ICultureDictionary>(),
                Mock.Of<IUmbracoComponentRenderer>(),
                new MembershipHelper(this.UmbracoContext, Mock.Of<MembershipProvider>(), Mock.Of<RoleProvider>()));

    Dave ,

    Thanks so much. Looks like we were working in parallel. I was studying Lars-Erik's blog at http://blog.aabech.no/archive/the-basics-of-unit-testing-umbraco-just-got-simpler/ in great detail and solved the problem as follows

    If you replace the TTUSPSTestInit() method in my original post with the following it works:

    public void TTUSPSTestInit()   
        {

            InitializeFixture();        // New
            try                     // New     
            {
                Initialize();           // New  <<<<<<<<<<<<<<<<<<  Note I think this was the main thing that fixed it.
            }
            catch (InvalidOperationException ex)    // New
            {
                if (ex.Message.StartsWith("Resolution is frozen"))  // New
                    throw new Exception("Resolution is frozen. This is probably because UmbracoSupport.DisposeUmbraco wasn't called before another UmbracoSupport.SetupUmbraco call.");         // New
            }
            content = Mock.Of<IPublishedContent>();
            var settings = SettingsForTests.GenerateMockSettings();
            SettingsForTests.ConfigureSettings(settings);       // New
            var currentPage = Mock.Of<IPublishedContent>();         // New
            var routingContext = this.GetRoutingContext("http://localhost", -1, umbracoSettings: settings);
            umbracoContext = routingContext.UmbracoContext;
            umbracoHelper = new UmbracoHelper(umbracoContext, content);
        }

    Note that even though I have this working I think I will thow that code away and use the "UmbracoSupport" Class and related approach as detailed by Lars-Erik's (after the heading "THE IMPLEMENTATION") in his blog at http://blog.aabech.no/archive/the-basics-of-unit-testing-umbraco-just-got-simpler/ .

    Dave's approach above also looks to be viable alternative and Dave thanks again for that.

    Thanks all :-)

    Hi Terry,

    In newer projects we also switched to the Umbraco Support class.

    But this is an older project where I copied the code from, before the Umbraco Support thing was released.
