You just need to test the filter itself. Just create an instance and call the OnActionExecuted() method with test data then check the result. It helps to pull the code apart as much as possible. Most of the heavy lifting is done inside the CsvResult class which can be tested individually. You don’t need to … Read more
MVC does not have an async-compatible action filter (but WebAPI does have one). For now, I recommend you use blocking calls in OnActionExecuting. Hopefully MVC will have a better story in the future. Update: You can vote here for the MVC team to add async filters.
The TypeFilterAttribute has an Argument property (of type object[]) where you can pass arguments to the constructor of the implementation.

Try: var url = filterContext.HttpContext.Request.Url;
If you’re working in a project contains both MVC and WebAPI assembilies, could you check what’s the namespace your ActionFilterAttribute’s namespace. It’s fairly confusing cause there are two ActionFilterAttributes under both: WebAPI: System.Web.Http.Filters MVC: System.Web.Http.Mvc
You could write a marker attribute: public class SkipMyGlobalActionFilterAttribute : Attribute { } and then in your global action filter test for the presence of this marker on the action: public class MyGlobalActionFilter : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { if (filterContext.ActionDescriptor.GetCustomAttributes(typeof(SkipMyGlobalActionFilterAttribute), false).Any()) { return; } // here do whatever you were intending … Read more

A better option is to implement the filter as a normal class into which you can inject whichever services you’d like: public class MyActionFilter … Read more
