未能用风帆运行 mocha 测试

Question

我正在关注 Sails 文档并尝试运行 Mocha 测试。 我已经按照文档指定的方式编辑了我的package.json，但由于某种原因，当我尝试运行 Mocha 时，我总是收到 EACESS，权限被拒绝错误。

一开始我得到了：

Error: EACCES, permission denied '/Library/Application Support/Apple/ParentalControls/Users'

我不明白为什么它必须对运行我的测试做任何事情，但添加了此文件夹所需的权限。

然后我得到了：

Error: EACCES, permission denied '/Library/Application Support/ApplePushService'

再次，不明白，所以改变了这个文件夹的权限，这也没有帮助。

我不明白为什么 Mocha 需要这些文件的权限，或者如何修复它。

我运行了命令：

mocha test/bootstrap.test.js test/unit/**/*.test.js

而且我的项目结构和 Sails 教程中的完全一样。

我正在使用 Mocha@2.2.5。 我的同事克隆了 repo，并尝试在他的机器上运行测试，但失败并出现完全相同的错误。

我尝试降级到 Mocha@2.2.0 这也没有帮助。

完整的错误跟踪：

Answer 1

看看我的sails.js test example。我想它可能会对你有所帮助。

如下图代码，参考test/bootstrap.js。

var Sails = require('sails');
var _ = require('lodash')
global.DOMAIN = 'http://localhost';
global.PORT = 1420;
global.HOST = DOMAIN + ':' + PORT;
before(function(callback) {
  this.timeout(7000);

  var configs = {
    log: {
      level: 'info'
    },
    connections: {
      memory: {
        // lets use memory tests ...
        adapter   : 'sails-memory'
      }
    },
    models: {
      connection: 'memory'
    },
    port: PORT,
    environment: 'test',

    // @TODO needs suport to csrf token
    csrf: false,

    // we dont need this configs in API test
    hooks: {
      grunt: false,
      socket: false,
      pubsub: false
    }
  };

  Sails.load(configs, function(err, sails) {
    if (err) {
      console.error(err);
      return callback(err);
    }

    console.log('rodo!')
    // here you can load fixtures, etc.
    callback(err, sails);
  });
});

after(function(done) {
  // here you can clear fixtures, etc.
  sails.lower(done);
});

Answer 2

我不确定它是否有帮助，但我遇到了类似的问题：当我在 shell 中输入 mocha 时，它在我的应用程序外部的文件夹中出现 EACCES 失败。 ：

/usr/local/lib/node_modules/mocha/bin/_mocha:372
    throw err;
    ^

Error: EACCES: permission denied, scandir '/backup/mint17.3/etc/cups/ssl'

我发现错误来自文件 ./test/mocha.opt 是我从sails.js 文档中写的评论：

/**
* @Doc :: This file should contain mocha configuration as described here:     https://mochajs.org/#mochaopts
*     
*    Note: The default test-case timeout in Mocha is 2 seconds. Increase
*      the timeout value in mocha.opts to make sure the sails lifting completes
*      before any of the test-cases can be started.
*/

--timeout 5s
