如何让我的NancyFX单元测试运行我的验证？

using Nancy;
using Nancy.Testing;
using NUnit.Framework;

[TestFixture]
public class MyNancyModuleTests
{
    private Browser _browser;

    [SetUp]
    public void Setup()
    {
        // 设置NancyFX的测试环境
        var bootstrapper = new ConfigurableBootstrapper(with =>
        {
            with.Module<MyNancyModule>(); // 设置要测试的Nancy模块
        });

        _browser = new Browser(bootstrapper);
    }

    [Test]
    public void TestValidation()
    {
        // 模拟HTTP请求并验证验证逻辑
        var response = _browser.Post("/validate", with =>
        {
            with.HttpRequest();
            with.FormValue("param", "value"); // 设置请求参数
        });

        Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);
        Assert.AreEqual("Validation successful", response.Body.AsString());
    }
}
