Expect matchers for sinon

Sinon Expect

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

A quick example is:

var object = {
  methodfunction(){}
};
 
//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.

Drop the first argument (the spy) otherwise the method signature is the same.
