asp.net – 我如何单元测试EntitySetController

控制器需要最少的CreateEntity和GetKey覆盖：

public class MyController : EntitySetController<MyEntity,int>
{
    protected override MyEntity CreateEntity(MyEntity entity)
    {
        return entity;
    }

    protected override int GetKey(MyEntity entity)
    {
        return entity.Id;
    }
}

MyEntity非常简单：

public class MyEntity
{
    public int Id { get; set; }
    public string Name { get; set; }
}

看起来你至少需要：
??请求带有URI
??请求标头中的3个键,MS_HttpConfiguration,MS_ODataPath和MS_ODataRouteName
??带路由的HTTP配置

[TestMethod]
    public void CanPostToODataController()
    {
        var controller = new MyController();

        var config = new HttpConfiguration();
        var request = new HttpRequestMessage();

        config.Routes.Add("mynameisbob",new MockRoute());

        request.RequestUri = new Uri("http://www.thisisannoying.com/MyEntity");
        request.Properties.Add("MS_HttpConfiguration",config);
        request.Properties.Add("MS_ODataPath",new ODataPath(new EntitySetPathSegment("MyEntity")));
        request.Properties.Add("MS_ODataRouteName","mynameisbob");

        controller.Request = request;

        var response = controller.Post(new MyEntity());

        Assert.IsNotNull(response);
        Assert.IsTrue(response.IsSuccessStatusCode);
        Assert.AreEqual(HttpStatusCode.Created,response.StatusCode);
    }

我不太确定IHttpRoute,在aspnet源代码中(我必须链接到这一点来解决这个问题)测试使用这个接口的模拟.因此,对于此测试,我只需创建一个模拟器并实现RouteTemplate属性和GetVirtualPath方法.测试期间未使用界面上的所有其他内容.

public class MockRoute : IHttpRoute
{
    public string RouteTemplate
    {
        get { return ""; }
    }

    public IHttpVirtualPathData GetVirtualPath(HttpRequestMessage request,IDictionary<string,object> values)
    {
        return new HttpVirtualPathData(this,"www.thisisannoying.com");
    }

    // implement the other methods but they are not needed for the test above      
}

这对我有用,但我真的不太确定ODataPath和IHttpRoute以及如何正确设置它.
