How to run unit tests in new web api builds

webapinightlyunittest.cs

// assuming we have an IoC container. Autofac example
var builder = new ContainerBuilder();
// assuming your global.asax.cs defines WebApiApplication : HttpApplication
builder.RegisterApiControllers(typeof(WebApiApplication).Assembly);
var container = builder.Build();

// getting the controller
var target = container.Resolve<MyController>();
var request = new HttpRequestMessage();
request.Properties[HttpPropertyKeys.HttpConfigurationKey] = new HttpConfiguration();
target.Request = request;

// now we can test
var correct = target.Get();
