Question

I apologize if this a duplicate question (I didn’t find anything like that).
I’m trying to build an OpenId Authentication service and unit test it, currently I have the following setup:

public class OpenIdAuthenticationService : IAuthenticationService
{
    private IConfigurationService   _configService;
    private OpenIdRelyingParty      _openIdRelyingParty;

    public OpenIdAuthenticationService(IConfigurationService configService)
    {
        _configService      = configService;
        _openIdRelyingParty = new OpenIdRelyingParty();            
    }
}

Apparently OpenIdRelyingParty requires access to HttpContext, is there a way to mock OpenIdRelyingParty and inject it the service ? Or maybe mock HttpContext and provide it to OpenIdRelyingParty somehow ?

Answer 1

To mock HttpContext for OpenIdRelyingParty you should modify the code of that class. Even you would waste some time mocking it due that it is a sealed class (but is not impossible you can use MOCKWCF).

I think that is better make a wrapper or adapter for OpenIdRelyingParty. like:

public class OpenIdRelyingPartyWrapped
{
    private OpenIdRelyingParty openIdRelyingPartyTarget;
    ....
    public virtual IAuthenticationRequest CreateRequest(string text)
    {
        return this.openIdRelyingPartyTarget.CreateRequest(text);
    }
    ...
} 

Then you will able to mock it as you want.
