javascript - Travis CI 在 Node Jasmine 测试中超时，但在本地通过

Question

我一直在 node 中开发一个命令行应用程序，它执行一些文件系统读取和表达应用程序的东西，我的所有测试都在本地通过，但是 Travis 在构建时似乎遇到了问题(超时，这是 Jasmine Node 的东西)。这是我得到的

.travis.yml

language: node_js
node_js:
  - '>=0.10'
before_script:
  - npm install -g grunt-cli
  - npm link
script:
  - "grunt --verbose"

sickmerge_spec.js

// Set the test environment
process.env.NODE_ENV = 'test';

// Dependencies
var exec = require('child_process').exec,
    fs = require('fs'),
    version = require('../package.json').version,
    request = require('request');
    // Helper function to exectue the sickmerge cli
    function execSickmerge (options, callback) {
        exec('sickmerge ' + options, function(err, stdout) {
            console.log(stdout);
            callback(stdout);
        });
    }
// ... Lots of other tests that exec the command, test below fails
describe('web application services', function() {
    it('should respond when with a 200 when http requested', function(done) {
        execSickmerge('./spec/fixtures/javascript.js', function() {
            request('http://127.0.0.1:3000/', function(err, response) {
                expect(response.statusCode).toEqual(200);
                done();
            });
        });
    });
});

});

您还可以看到the code on github , 和 builds in Travis .我最初认为 app.list() 阻止了控制台的执行，但删除它也没有用。

Travis 是否只是阻止某些端口？它不允许文件系统查询吗？

看起来像the current script正在工作，这是:

.travis.yml

language: node_js
node_js:
  - '>=0.10'
before_install:
  - npm install -g grunt-cli
before_script:
  - npm link
script:
  - "grunt --verbose"

Does it not allow filesystem queries?

Travis-CI 允许文件系统查询。
