我正在为一个函数编写测试代码，该函数将检查 twitter 中是否存在用户名。我正在使用 Hapi 框架和实验室进行测试。

当我运行时，npm test我收到以下错误：

> NameGen@0.0.0 test /Users/mario/projects/NameGen
> ./node_modules/lab/bin/lab -c


/Users/mario/projects/NameGen/test/test.js:5

npm ERR! Test failed.  See above for more details.

我的测试代码是：

var Lab = require("lab");
var server = require('../'); // require index.js
var request = require('request');

Lab.experiment( "Test Username Existence", function() {
  // tests

  Lab.test( "Test username exists", function(done){
    var options = {
      url: 'http://twitter.com/BarackObama'
    };

    request(options, function(error, response, body){
      Lab.expect(response.statusCode).to.equal(200);
    });
      done();
    });

    Lab.test("Test username does not exists", function(done){
      var options = {
        url: 'http://twitter.com/jhkhksdhkjahsdfkjhasdf'
      };

      request(options, function(error, response, body){
        Lab.expect(response.statusCode).to.equal(404);
      });
        done();
      });

  });

package.json我在我的文件中安装了最新版本的节点和所有必要的依赖项。什么可能导致此错误？

正如@Jordonias 所说。但是，当我使用他的示例时，它仍然不起作用。我不得不将第二行更改为：

lab = exports.lab = Lab.script()

根据实验室文档：Test files must require the lab module, and export a test script

测试.js

var Lab = require('lab');
var lab = module.exports = Lab.script();

lab.experiment( "Test Username Existence", function() {
  lab.test( "Test username exists", function(done){

   });
});
