StructureMap: How can i unit test the registry class?
- by Marius
I have a registry class like this:
public class StructureMapRegistry : Registry
{
public StructureMapRegistry()
{
For<IDateTimeProvider>().Singleton().Use<DateTimeProviderReturningDateTimeNow>();
}
I want to test that the configuration is according to my intent, so i start writing a test:
public class WhenConfiguringIOCContainer : Scenario
{
private TfsTimeMachine.Domain.StructureMapRegistry registry;
private Container container;
protected override void Given()
{
registry = new TfsTimeMachine.Domain.StructureMapRegistry();
container = new Container();
}
protected override void When()
{
container.Configure(i => i.AddRegistry(registry));
}
[Then]
public void DateTimeProviderIsRegisteredAsSingleton()
{
// I want to say "verify that the container contains the expected type and that the expected type
// is registered as a singleton
}
}
How can verify that the registry is accoring to my expectations? Note: I introduced the container because I didn't see any sort of verification methods available on the Registry class. Idealy, I want to test on the registry class directly.
