Automatic testing of ApiController

Question

I have an ApiController and would like to test it with unit tests including the routing.

An example:

[RoutePrefix(\"prefix\")]
public class          


        

Answer 1

That is an integration test, not a unit test. If you wanted to automate this you would have to have a tool that would launch/host your web api and then execute requests against it.

If you wanted to keep it as a unit test though you could validate the attributes on the class and the method and check the values.

var type = typeof(Controller);
var attributeRoutePrefix = type.GetCustomAttribute(typeof(RoutePrefixAttribute)) as RoutePrefixAttribute;
Assert.IsNotNull(attributeRoutePrefix);
Assert.AreEqual("prefix", attributeRoutePrefix.Prefix);

var methodAttribute = type.GetMethod(nameof(Controller.Add)).GetCustomAttribute(typeof(RouteAttribute)) as RouteAttribute;
Assert.IsNotNull(methodAttribute);
Assert.AreEqual("id1", methodAttribute.Template);
