json - 在 Nancy 中对 JSON ModelBinding 进行单元测试

Question

我正在尝试在 NancyFx 中测试 JSON 模型绑定(bind)。

请求在浏览器中测试时有效，但我无法让单元测试通过。当我调试测试时，我发现返回的模型是 null from

 var model = this.Bind<EventRequestModel>();

始终为空；

这是我正在做的一个简化示例:

南希模块:

    Post["/Events"] = _ =>
    {
        // Convert request to model and validate
        try
        {
            var model = this.Bind<EventRequestModel>();
            var result = this.Validate(model);
            if (!result.IsValid)
                throw  new Exception("Model was not valid");

            return HttpStatusCode.OK
         }
         catch (Exception ex)
         {
             _logger.LogError(ex);
             return HttpStatusCode.BadRequest;
         }                    
     };

单元测试:

    [Fact]
    public void ReturnOkOnGoodRequest()
    {
        // Create a valid model
        var model = new EventRequestModel()
            {
                TopRightLat = 100,
                TopRightLong = 100,
                BottomLeftLat = 100,
                BottomLeftLong = 100
            };

        var response = _browser.Post("/API/Events", with =>
            {
                with.JsonBody(model);
            });

        Assert.Equal(HttpStatusCode.OK, response.StatusCode);
     }

我也尝试过将 JSON 直接写入正文并执行如下操作:

    var json = "{'TopRightLat' : 0, 'TopRightLong': 0, 'BottomLeftLat':  0, 'BottomLeftLong': 0}"
    var response = _browser.Post("/API/Events", with =>
        {
            with.Header("Content-Type", "application/json");
            with.Body(json);
         });

此 JSON 正文在我手动测试端点时有效，但在我的单元测试中无效。我做错了什么？

Answer 1

失败的原因是因为我在设置测试时没有将模型绑定(bind)依赖项添加到 ConfigurableBootstrapper。

这(在测试设置中)修复了它

_bootstrapper = new ConfigurableBootstrapper(with =>
{
    ...
    with.Dependency<IFluentAdapterFactory>(_fluentValidationFatory);
    with.Dependency<IModelValidatorFactory>(_modelValidatorFactory);
    ...
}
