Description and Quickstart

Description

umock is a library for creating mock objects of Interfaces and (when possible) Classes.

Quickstart

Consider this little interface:

 interface IPoint {
  var x : Int;
  var y : Int;
  function length() : Int;
 }

With umock, we can mock this interface like this:

 import umock.Mock;
 ...
 var mock = new Mock<IPoint>(IPoint); 

 mock.setupField("x").returns(10); 
 mock.setupField("y").throws("One dimension only, thank you.");
 mock.setupMethod("length").returns(1000);

Setting parameter constraints is also possible:

 mock.setupMethod("someMethod").withParams(It.IsAny(Int), "123").returns(1000);

So are callbacks and lazy return evaluation:

 mock.setupMethod("someMethod").returns(1000).callBack(function() { i++; });
 mock.setupMethod("someMethod").returnsLazy(function() { return 100+i; });

And finally, verifying the results:

 mock.verify("length", Times.atLeastOnce());

Supported platforms

Right now the following platforms are supported:

• Neko
• Php
• Javascript

Inspiration

This library is heavily influenced by the great Moq library for .NET.
