i try to unit test an EntitySetController. I can test Get but have problems in testing the Post Method.
I played around with SetODataPath and SetODataRouteName but when i call this.sut.Post(entity) i get a lot of errors regarding missing Location Header, missing OData-Path, missing Routes.
I am at my wit's end. Is there anybody out there who has successfully testet their EntitySetController?
Has anybody an idea for me? Maybe should i test only the protected overrided methods from my EntitySetController implementation? But how can i test protected methods?
Thanks for your help
Came here looking for a solution aswell. This seems to work however not sure if there is a better way.
The controller needs a minimum of CreateEntity
and GetKey
overrides:
public class MyController : EntitySetController<MyEntity, int>
{
protected override MyEntity CreateEntity(MyEntity entity)
{
return entity;
}
protected override int GetKey(MyEntity entity)
{
return entity.Id;
}
}
Where MyEntity is really simple:
public class MyEntity
{
public int Id { get; set; }
public string Name { get; set; }
}
Looks like you need at least:
+ Request with a URI
+ 3 keys in the request header, MS_HttpConfiguration
, MS_ODataPath
and MS_ODataRouteName
+ A HTTP configuration with a route
[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);
}
I'm not too sure about the IHttpRoute
, in the aspnet source code (I had to link to this to figure this all out) the tests use mocks of this interface. So for this test I just create a mock of this and implement the RouteTemplate
property and GetVirtualPath
method. All the others on the interface were not used during the test.
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
}
This is working for me however I am really not too sure about the ODataPath
and IHttpRoute
and how to set it correctly.
