使用路由属性对Api控制器进行单元测试

Question

我认为在网络上进行简单搜索的结果不止于此。

最接近解决方案的是首先使用属性进行路由的方法：AttributeRouting not working with HttpConfiguration object for writing Integration tests

但是ASP.NET Web Api 2呢？

我的单元测试

HttpConfiguration config = new HttpConfiguration();
// config.MapHttpAttributeRoutes(); // This doesn't work. I guess there is needed some more plumbing to know what Controllers to search for attributes, but I'm lost here.
HttpServer server = new HttpServer(config);

using (HttpMessageInvoker client = new HttpMessageInvoker(server))
{
    using (HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Put, "http://localhost/api/accounts/10"))
    using(HttpResponseMessage response = client.SendAsync(request, CancellationToken.None).Result)
    {
        response.StatusCode.Should().Be(HttpStatusCode.Created);
    }
}

如何注入我的控制器，以便它在Controller上读取属性并设置路由，以便我可以实际进行一些测试？

Answer 1

这太荒谬了......我用它来解决这个问题：

config.MapHttpAttributeRoutes();
config.EnsureInitialized();

基本上，这会运行config.MapHttpAttributeRoutes()配置的初始化。我想，我原本以为这是自动完成的。

但现在它有效，我很高兴。
