对象#< Object>没有方法“类型" [英] Object #<Object> has no method 'type'

问题描述

我的测试代码是

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');
  });

});

当我运行此测试时，它给我错误

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

1) passport-twitter should export Strategy constructor directly from package:
     TypeError: Object #<Object> has no method 'type'
      at Context.<anonymous> (/home/ritesh/projects/passport-topcoder/test/module.test.js:7:26)

      at processImmediate [as _immediateCallback] (timers.js:330:15)

  2) passport-twitter should export Strategy constructor:
     TypeError: Object #<Object> has no method 'type'
      at Context.<anonymous> (/home/ritesh/projects/passport-topcoder/test/module.test.js:11:35)

      at Object._onImmediate (/usr/local/lib/node_modules/mocha/lib/runner.js:261:5)
      at processImmediate [as _immediateCallback] (timers.js:330:15)

但是类型方法是在文档中指定的.如何消除此错误.请提供一些帮助.

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

当我尝试运行时代替

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');
  });

});

我仍然收到错误

     TypeError: Object #<Object> has no method 'type'

推荐答案

should.js具有以下语法:

'xxxx'.should.be.type('string');

Should.js文档#类型
