Question

我一直在节点中的命令行应用程序上做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传递，但是Travis在构建时似乎遇到了问题（超时，这是一个Jasmine Node的事情）。这就是我所拥有的

.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();
            });
        });
    });
});

    console.log(

        'Press CTRL+C if you\'ve closed your web browser and didn\'t click either of those buttons.'
    );
    app.listen(port);
    if( env !== 'test') open('http://' + hostname + ':' + port);
});

您还可以看到the code on github和builds in Travis。我原本以为app.list（）阻止了控制台的执行，但删除它也不起作用。

Travis是否只阻止某些端口？它不允许文件系统查询吗？

看起来the current script正在发挥作用：

<强> .travis.yml

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

是否不允许文件系统查询？

Travis-CI确实允许文件系统查询。

Travis CI在节点茉莉花测试中超时，但在本地传递
