Versatile Dynamic Mocking for NodeJS

SuperMock

Versatile Dynamic Mocking for Node.JS

SuperMock is a very powerful, lightweight, versatile, buzzword, buzzword, mocking library for NodeJS. Influenced by Python's Mock, SuperMock allows you to write mocks with as little setup code as possible.

SuperMock requires harmony-proxies to be enabled

   node --harmony-proxies
   var SuperMock = require('supermock').SuperMock,
       assert = require('assert');
 
   //myMock is a function, but also an object 
   var myMock = new SuperMock();
 
   myMock('foo', 'bar');
 
   //SuperMock keeps track of how many times it has been called 
   myMock.assertCallCount(1);
 
   //it also keeps track of what it was called with 
   myMock.assertCalledWith('foo', 'bar');
 
   //SuperMock will return a new SuperMock object for everything 
   myMock.foo.bar.baz.something = 42;
   assert.equal(myMock.foo.bar.baz.something, 42);
 
   myMock.foo.bar.baz.func();
   myMock.foo.bar.baz.func.assertCallCount(1);
 
   //unless you specify it 
   var myMock = new SuperMock({returnValue:'42', foo:'bar'});
   assert.equal(myMock(), 42);
   assert.equal(myMock.foo, 'bar');
 
   //Supermock can also throw errors 
   var myMock = new SuperMock({ throws: new Error('i haz a boo boo') });
   assert.throws(myMock, Error);
 
  //You can also get the information without having to assert 
  myMock.getCallCount() => 1
  myMock.getCalledWith() => [ [] ]
 
  //you can also access the returnValue 
  var myMock = new SuperMock();
  myMock('123')('456')('789');
  myMock.assertCalledWith('123');
  myMock.returnValue.assertCalledWith('456');
  myMock.returnValue.returnValue.assertCalledWith('789');
