Your secondMasterTesting is probably hidden because is either inside ContentPlaceHolder or you call it from some other page than the one the control is registered.

To solve the error try

if(secondMasterTesting != null)
  secondMasterTesting.Text = "Hello World form Second Master";

The code behind is search on belonging page for that control.
