使用Nancy.Testing.Browser发布时出现ConfigurableBootstrapper错误

Question

我有一个简单的NancyModule，它有一个Post声明：

Post["/Car/New"] = args => 
{
    Car newCar = this.Bind<Car>();
    newCar = _carRepos.CreateNewCar(newCar);
    return Response.AsJson<Car>(newCar);
};

从视图发布到此工作正常：

<form action="/Car/New" method="post">
    <input type="text" name="colour" />
    <input type="submit" value="Submit" />
</form>

当我尝试为此路线运行测试时，出现以下错误：

System.Exception : ConfigurableBootstrapper Exception
  ----> Nancy.RequestExecutionException : Oh noes!
  ----> System.MissingMethodException : Method not found: '!!0 Nancy.ModelBinding.ModuleExtensions.Bind(Nancy.INancyModule, System.String[])'.

这是我的考验：

[Test]
public void PostNewCarReturnsCar()
{
    var browser = BrowserFactory.Create();
    var response = browser.Post("/Car/New", with =>
    {
        with.FormValue("Colour", "Red");
    });

    var car = GetObjectFromJsonBody(response.Body.AsString());

    Assert.IsNotNull(car);
    Assert.AreEqual(2, car.Id);
}

这是我的测试Bootstrapper：

public class NancyBootstrapper : ConfigurableBootstrapper
{
    public NancyBootstrapper()
        : base(with => { with.Module<CarsModule>(); })
    { }

    protected override void ConfigureApplicationContainer(TinyIoCContainer container)
    {
        container.Register<ICarRepository>(new FakeData.CarRepository());
    }
}

我是否必须在ConfigurableBootstrapper中执行任何特殊操作才能使绑定生效？

Answer 1

仔细检查您的packages.config是否正在推出正确的版本。

更新：因为这主要来自@StevenRobbins，所以我在背后给了他一个轻拍：

Answer 2

@Jon检查packages.config的建议是正确的。尽管使用相同的方法在几分钟之内添加了包，但测试项目的Nancy版本比Web项目更旧。更新到正确版本，现在工作正常。
