Registration of dependencies outside the registrar

[magarich228]

Hello, can I access IUnityContainer and register a dependency in it somewhere outside the RegisterInternal method?

public class MyRegistrar : RegistrarBase<IUnityContainer> 
{
    protected override void RegisterInternal(IUnityContainer container)
    {
        //
    }
}

I have such a situation on my project that tests are launched only from the code like this:

public XmlNode SomeMethod(LargeObject obj)
{
    var testPackage = new TestPackage(Assembly.GetExecutingAssembly().Location);
    var runner = TestEngineActivator.CreateInstance().GetRunner(testPackage);
    var result = runner.Run(null, TestFilter.Empty);
    return result;
}

In the code above there is some object of LargeObject type, which exemplar I cannot create manually in the RegisterInternal method. I need to somehow register it in IUnityContainer for injection into the test, preferably directly in the SomeMethod method.
