To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.

You need to register an instance of ITestOutputHelper as described in the README.md.

builder.Register(context => new TestOutputHelper())
                .As<ITestOutputHelper>()
                .InstancePerLifetimeScope();

I followed all the steps as given in documentation. still I am getting same error.

dennisroche commented 8 years ago

That is odd. Can you provide a sample that reproduces the issue?

dennisroche commented 7 years ago

Closing. I'll reopen if sample/repo of the issue appears.

@dennisroche See http://stackoverflow.com/questions/43450788/xunit-test-with-autofac for a description in greater detail. Actually you have to register the TestOutputHelper also AsSelf() since the AutofacTestInvoker resolves an instance of this class.

So the correct way of initializing the Autofac-Infrastructure to get the library running could be

            builder.Register(context => new TestOutputHelper())
                .AsSelf()
                .As<ITestOutputHelper>()
                .InstancePerLifetimeScope();

You should consider adopting the README.md, I ran into the same problem today.

@peterwurzinger thanks. would you mind putting up a PR to update the README.md?
