My test code is

var strategy = require('../lib');
var should = require("should");
describe('passport-twitter', function() {

  it('should export Strategy constructor directly from package', function() {
    console.log('strategy is',strategy);
    strategy.should.have.type('function');
  });

  it('should export Strategy constructor', function() {
    strategy.Strategy.should.have.type('function');
  });

});

and when i run this test.it is giving me error

but the type method is specified in documentation.how to get rid of this error.please help a bit.

instead of this when i try to run

aa

var strategy = require('..');
var should = require("should");
describe('passport-twitter', function() {

  it('should export', function() {
    console.log('strategy is',strategy);
   'xxxx'.should.have.type('function');
  });

});

still i am getting the error
