Programaticaly simulate user interaction for Unit Testing in Google Dart -


I'm trying to write some unit tests for complex menus in one place and I simulate user interaction with that menu Want to do

I've found that it is possible to simulate a click with the query code selector ("# myElement"). () , but I would like to be able to trigger more complex events like mouseDown document , mouseMove , < Code> TouchStart and touchEnd in a particular place. , e.t.c.

I found a way to do this. It's still not perfect or not right, but it provides anything I need. 

  import 'dart: html'; Import 'dart: async'; Zero main () {// Create target element DivElement menuSprite = new DivElement () .. style. Hight = "50px" .. style.wind = "50px" .. style.bird = "1px solid black"; document.body.children.add (menuSprite); // Esine Event Listener MenuSprite ..onMouseDown.listen ((E) => MenuSprite.style.backgroundColor = "red") ..onMouseUp.listen ((E) => Menu Sprite.style.backgroundColor = " Blue ") ..onTouchStart.listen ((e) => menuSprite.style.backgroundColor =" orange ") ..TouchEnd.listen ((E) => menuSprite.style.backgroundColor =" gray "); // Create event // TODO: see more parameters of the events or are more specific // see: // * https://api.dartlang.org/apidocs/channels/stable/dartdoc-viewer/dart-dom-html MouseEvent // * https://api.dartlang.org/apidocs/channels/stable/dartdoc-viewer/dart-dom-html.TouchEvent // // Warning: Event Type Case Is Sensitive ('MouseDown' Not Working) . Event myMouseDown = new event ('Masudown'); Event myMouseUp = new event ('mouseup'); Event myTouchStart = new event ('TouchStart'); Event myTouchEnd = new event ('touchend'); // TODO: Mousemove and Touch Moche Event // We can fire events using "Element.dispatchEvent ()". New Future Indispensable (new period (millisecond: 500), () => display menu; disaccharart (mimehouse)); New Future Indispensable (new period (millisecond: 1000), () => display menu; disseachable event (mimahaheusup)); New Future (New period (millisecond: 1500), () => menuSprite.dispatchEvent (myTouchStart)); New Future Indispensable (new period (milliseconds: 2000), () => display menu; disseachable event (matte touchand)); }   
 I have found this idea:

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
