hop of those help? how come Game is not a function when imported via System , The module object in your case isn't Game, it contains Game. Try:
System.import('Game').then(function ({Game}) {
  game = new Game();
});

How to make a function/class from an imported library accessible for all the libraries imported below in Dart?


Tag : dart , By : Antony Briggs

seems to work fine You have to make the imports in every library you want to use other libraries.
What you might do is to join several files to one library using part 'model.dart'; (parent file) and part of app; (linked file).

System.ComponentModel.Component is a class but acts like a VB.NET module or an imported class (but isn't)

I wish this helpful for you How is it that properties like System.ComponentModel.Component.DesignMode are available without the fully-qualified name, i.e. just via DesignMode without the Component class? , You are probably developing a Control. All Controls are Components:
System.Object 
  System.MarshalByRefObject
    System.ComponentModel.Component
      System.Windows.Forms.Control
          {your control here}

Python Calling a function within a class, within a function, from an imported module

it helps some times You don't need a main function in test1 file. Just have the Class C in there.
test1.py
class C:
    def function6(self):
        print ("Hello")
    def function7(self):
        print ("Trudy")
 def sayHello():
    C().function6()
 def sayWorld():
    C().function7()
import test1
def function2():
    print ("World")

test1.C().function6()
function2()

Should System be explicitly imported in a Xamarin.Android class file?

Hope this helps You ask that question because you have a misunderstanding between the using directive and referenced assemblies.
using does not reference any assembly.

How can I spy on an imported function in a grandparent class when testing a child class?


Tag : javascript , By : Cadu

I hope this helps you . GrandparentClass.js requires nodeModule.js and grabs a reference to nodeModuleFunction as soon as it runs...
...so you just need to make sure your spy is in place before it runs:
const nodeModule = require('./nodeModule');
const sinon = require('sinon');

describe('ChildClass test', () => {

  describe('Sinon spy', () => {

    it('should call nodeModule.nodeModuleFunction with given value', done => {

      const spy = sinon.spy(nodeModule, 'nodeModuleFunction');  // create the spy...
      const ChildClass = require('./ChildClass');  // ...and now require ChildClass

      const object = new ChildClass();

      expect(object.message).not.toBeNull();  // Success!
      expect(spy.called).toBe(true);  // Success!
      expect(spy.withArgs('Some input').calledOnce).toBe(true);  // Success!

      object.message.then(message => {
        expect(message).toBe('Returned from node module.');  // Success!
        done();
      });
    });

  });

});
