Sinon Expect

Sinon expect is a wrapper for the assertions built into sinon.

A quick example is:

var object = {
  method: function(){}
};

//Yes we are overriding expect
//You can also save it to another variable but that is ugly
expect = require('sinon-expect').enhance(expect, sinon, 'was');

sinon.spy(object, 'method');

//Assert style
sinon.assert.called(object.method);

//Expect style
//All assertions are found under the .spy namespace/"flag"
expect(object.method).was.called();

See Sinon Assertions for additional documentation for each of these assertions.
