CreatedAtRoute using Attribute-based routing and Unit Testing

Question

User-638259267 posted

I found this code example http://www.asp.net/web-api/overview/testing-and-debugging/unit-testing-controllers-in-web-api which addresses using the CreatedAtRoute return type for IHttpActionResult when using default routing as configured in WebApiConfig.cs, however, it does not address how to handle this while using Attribute-based routing.

How does the CreatedAtRoute method need to be populated correctly when using Attribute-based routing and consequently how is this supposed to be Unit Tested in this scenario also?

Please advise.

Thanks.

Hi vs2010junkie,

does the CreatedAtRoute method need to be populated correctly when using Attribute-based routing

You can try to give the route a name and pass that in to the CreatedAtRoute method. This is done by setting a Name property on the Route. You can call the CreatedAtRoute method from the PostMessage action and pass in the route name.

The following code for your reference.

       [Route("api/values/{id}", Name = "GetMessage")]
        public IHttpActionResult PostMessage(Message message)
        {
            return CreatedAtRoute("GetMessage", new { id = message.ID }, message);
            //return CreatedAtRoute("DefaultApi", new { id = message.ID }, message);
        }

If I have numerous Web API Controllers all named the same (Get, Post, Put, Delete) and specify a Route Name that all match "Post", "Put", "Delete", "Get" , "GetById", will this cause a conflict when doing the routing or do all of these names have to be unique per method in each Web API Controller?

Please clarify.

Thanks.

This is not a conflict because each of us is a unique controller. You can refer the following tutorials about Web API Routing.

How ASP.NET Web API routes HTTP requests to controllers and actions:
