public class MyFilter: ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext context) { if (context.HttpContext.Request.Path.Value.Contains("/abc/")) { context.Result = new ContentResult() { Content = "拒绝访问" }; } base.OnActionExecuting(context); } }
对Filter的测试最主要的是模拟ActionExecutingContext参数，以及其中的HttpContext等，然后对预期进行Assert。
[TestMethod()] public void OnActionExecutingTest() { var filter = new MyFilter(); var actContext = new ActionContext(new DefaultHttpContext(),new RouteData(), new ActionDescriptor()); actContext.HttpContext.Request.Path = "/abc/123"; var listFilters = new List<IFilterMetadata>(); var argDict = new Dictionary<string, object>(); var actExContext = new ActionExecutingContext( actContext , listFilters , argDict , new AccountController() ); filter.OnActionExecuting(actExContext); Assert.IsNotNull(actExContext.Result); Assert.IsInstanceOfType(actExContext.Result, typeof(ContentResult)); var cr = actExContext.Result as ContentResult; Assert.AreEqual("拒绝访问", cr.Content); actContext = new ActionContext(new DefaultHttpContext(), new RouteData(), new ActionDescriptor()); actContext.HttpContext.Request.Path = "/1/123"; listFilters = new List<IFilterMetadata>(); argDict = new Dictionary<string, object>(); actExContext = new ActionExecutingContext( actContext, listFilters, argDict, new AccountController() ); filter.OnActionExecuting(actExContext); Assert.IsNull(actExContext.Result); }
