Question

I am getting “Cannot access a closed Stream” when unit testing a Nancy web app.

My module is as follow:

public class MainModule : NancyModule
{
    public MainModule()
    {
        Get["/{Name}"] = p =>
            {
                var command = this.Bind<MainCommand>();
                return Response.AsJson(command.ExecuteGetMessage());
            };
    }
}

And my test is:

    [Test]
    public void Should_return_welcome_message()
    {
        // When
        var bootstrapper = new DefaultNancyBootstrapper();
        var browser = new Browser(bootstrapper);

        BrowserResponse browserResponse = browser.Get("/", with =>
            {
                with.HttpRequest();
            });

        Console.WriteLine(browserResponse.StatusCode);
        Console.WriteLine(browserResponse.Body.ToString());

        // Then
        Assert.AreEqual(HttpStatusCode.OK,browserResponse.StatusCode);
    }

UPDATE: I am getting StatusCode = NotFound and the exception happens when trying to access browserResponse.Body.

I had a look at the Nancy forum and also here at StackOverflow.
I tried this solution: Nancy test doesn't find route in other assembly

but still not working.

When I run the test in debug mode I see that my module is been called but I still cant check the returned value.

What should I do in order to get it working?

Thanks

You are getting a NotFound response because the route you have defined is different from the route you have called.

You are calling / in your test, but the module has a route of /{Name}.

The exception is because there is no body with a NotFound response.

Update your test to something like:

var bootstrapper = new ConfigurableBootstrapper(c=>c.Module<MainModule>());
var browser = new Browser(bootstrapper);
BrowserResponse browserResponse = browser.Get("/ademar", with =>
        {
            with.HttpRequest();
        });
