【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');
  });

});

当我运行这个测试时，它给了我错误

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)

  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)

但是在文档中指定了类型方法。如何摆脱这个错误。请帮助一下。

当我尝试运行时而不是这个

啊

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'

【问题讨论】：

不清楚你需要什么策略变量
在控制台日志中的策略是 { version: '1.0.0', Strategy: { [Function: Strategy] super_: { [Function: OAuth2Strategy] super_: [Function: Strategy] } } } 我们是得到这个。
即使它在我更新时给我同样的字符串错误

标签： node.js npm mocha.js should.js

【解决方案1】：

should.js 的语法如下：

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

Should.js documentation # type
