在 Mocha 中使用 PhantomJS 的问题

Question

我在尝试从我的 Mocha 测试套件向服务器发送 PhantomJS 调用时遇到问题。

问题

我正在尝试使用 PhantomJS 对端点进行调用。我的第一个电话正常工作。

但是我有两个问题：

• 当前脚本第一次运行良好，但连续运行看一些文件导致测试失败。我要解决这个问题吗？
• 这似乎不是进行这些测试的好方法，有更好的替代方法吗？

设置：

• Gulp 作为观察者
• gulp-mocha 运行测试
• phantom-sync 做一些端到端测试

Mocha 测试文件（简体）：

if(typeof process != 'undefined') {
  var should = require('chai').should();
  var _ps = require('phantom-sync');
  var phantom = _ps.phantom;
  var sync = _ps.sync;
}

describe('Login', function() {
  this.timeout(5000);

  it('should be able to open CMS', function(done) {

    sync(function() {
      var ph = phantom.create();
      var page = ph.createPage();
      var status = page.open('http://www.google.com'); // Get a default CMS url...
      status.should.equal('success');
      ph.exit();
      return done();
    });

  });

  it('should redirect after successful login');

});

Gulpfile（简化版）：

gulp.task('test-develop', ['scripts'], function() {
  return test(null, true);
});

var keepAlive = false;

function test(reporter, _keepAlive) {

  keepAlive = _keepAlive;

  return gulp.src('test/**/*.js')
    .pipe(plugins.plumber())
    .pipe(plugins.mocha({ reporter: reporter || 'spec' })
      .on('error', onError));

}

function onError(err) {

  console.log(err.toString());
  if (keepAlive) {
    this.emit('end');
  } else {
    // if you want to be really specific
    process.exit(1);
  }

}

gulp.task('watch-test', function() {
  gulp.watch('test/**/*.js', ['test-develop']);
});

错误：

它最终状态为邪恶，Phantom 在被要求时没有正确清除它的缓存和 cookie。
