QUnit Mock

QUnit Mock provides some mock assertions and stubs for QUnit.

Installation

Just download the qunit.mock.js and include it after QUnit.

Expecting calls

See an example of expecting calls:

MyClass = function() {}

MyClass.prototype = {
  methodOne: function() {
    this.methodTwo();
  },
  
  methodTwo: function() {},
  
  methodThree: function() {
    this.methodTwo();
    this.methodTwo();
  }
};

test("calls second method on first", function() {
  obj = new MyClass();
  expectCall(obj, "methodTwo"); // expect the method call
  obj.methodOne();
});

test("calls second method two times on third", function() {
  obj = new MyClass();
  expectCall(obj, "methodTwo", 2); // this time saying number of expect calls
  obj.methodThree();
});

At end of test it will automatic check if the method is called and will test it.

Stubbing

See an example of stubbing methods:

MyClass = function() {}

MyClass.prototype = {
  someMethod: function() { return "hello"; }
}

obj = new MyClass();

test("stubbing method", function() {
  stub(obj, "someMethod", function() { return "world" });
  equal(obj.someMethod(), "world"); // ok, will pass
});

test("method after stub method", function() {
  equal(obj.someMethod(), "hello"); // ok too
});

Stubbing is easy, also, note in second test the method returned to original state, after the test finish all stubs will be removed and object will keep original ones.
