Hey @all,

i am trying to set up a test project for my site, especially for my search request on examine index. The index in working well in the umbraco site but not in my test project.

This is my code which is causing the exception:

var index = ExamineManager.Instance.SearchProviderCollection["ApartmentCatalogIndexer"];

This is the following exception/stacktrace:

System.Configuration.ConfigurationErrorsException : Exception has been thrown by the target of an invocation. (C:\Users\Thobi\AppData\Local\Temp\c23yba53.cr1\config\ExamineSettings.config line 12) ----> System.Reflection.TargetInvocationException : Exception has been thrown by the target of an invocation. ----> System.NullReferenceException : Object reference not set to an instance of an object.

at System.Web.Configuration.ProvidersHelper.InstantiateProvider(ProviderSettings providerSettings, Type providerType) at System.Web.Configuration.ProvidersHelper.InstantiateProviders(ProviderSettingsCollection configProviders, ProviderCollection providers, Type providerType) at Examine.ExamineManager.EnsureProviders() in x:\Projects\Examine\Examine\Projects\Examine\ExamineManager.cs:line 98 at Examine.ExamineManager.getSearchProviderCollection() in x:\Projects\Examine\Examine\Projects\Examine\ExamineManager.cs:line 60 at UmbracoProject.WebsiteTest.UnitTests.Website.Index.IndexSearchTest.IndexSearchTestSearchRegionWithSpecialCharacters() in c:\Users\Thobi\Repository\UmbracoProject\UmbracoProject.WebsiteTest\UnitTests\Website\Index\IndexSearchTest.cs:line 26 --TargetInvocationException at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck) at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark) at System.Activator.CreateInstance(Type type, Boolean nonPublic) at System.Activator.CreateInstance(Type type) at System.Web.HttpRuntime.CreatePublicInstance(Type type) at System.Web.Configuration.ProvidersHelper.InstantiateProvider(ProviderSettings providerSettings, Type providerType) --NullReferenceException at UmbracoExamine.UmbracoContentIndexer..ctor()

The config files seems to be okay for me and i also copied the existing index to the debug output folder.

Has anyone an idea, whats wrong?

For me its looking fine, do you see something wrong?

The config files are located at the /debug/config folder in the test procect. Maybe the location is the problem? But while running the config files are copied to the temp folder.

Thanks for your help.

Update:

This is a Examine issue. The AppDomainAppId is not null checked. In case that its a class library for unit testing, the AppDomainAppId is null.

We can close this ticket.
