  UnitTesting an ASP.NET WebForms page

  Apr 27, 2012 04:30 PM|LINK

  Hey guys,

  I want to write some unit tests for an ASP.NET WebForms app and I get a MissingMemberException when I try to invoke a private method from the page (private bool MyPrivateMethod()): System.MissingMethodException: Method 'MyPrivateMethod' not found

  The unit test method looks like this:

  [TestMethod]
  [UrlToTest("http://localhost:25153/MyPage.aspx")]
  [HostType("ASP.NET")]
  [AspNetDevelopmentServerHost(SITE_LOCAL_PATH, SITE_ROOT)]
  public void When_populating_the_grid()
  {
         try
         {
                  System.Diagnostics.Debugger.Break();
                  PrivateObject po = new PrivateObject(TestContext.RequestedPage);
  
                  object response = po.Invoke("MyPrivateMethod", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
  
                  Assert.IsTrue(Convert.ToBoolean(response));
         }
         catch (Exception ex)
         {
                  throw ex;
         }
  }

  If I write simple Reflection code for this method, the method gets called (a BP gets hit).

  Type t = typeof(MyPage);
  var m = t.GetMethod("MyPrivateMethod", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
  
  // var i = Activator.CreateInstance(t);
  // m.Invoke(i, null); // <- this also works
  m.Invoke(TestContext.RequestePage, null);

  What am I missing?

  Thanks

  Happy coding!

  I would use this method instead of reflection to test private methods

  Hey,

  I will try this but I don't like the note: "The use of Accessors has been deprecated in Visual Studio 2010 and might not be included in future versions of Visual Studio."

  Thanks.

  Happy coding!
