完成后，Testem gulp任务会挂起 [英] Testem gulp task hangs after finished

问题描述

这个gulp任务完成后不会退出，我必须手动按
Ctrl-C退出。

  gulp.task（'test'，function（done）{
 var testem = require（'testem'）; 
 
 var testemOptions = {
 file：'testem。 json'
}; 
 
 var t = new testem（）; 
 
 t.startCI（testemOptions，done）; 
}）; 
  

我怎样才能让这个任务正常退出？

输出：

<$>

注意：实际上它会自行退出，但完成后需要15秒。 p $ p> [15:49:59]使用gulpfile〜/ gulpfile.js

解决方案后完成'test'

使用 Chromium启动器管理重现您的问题，但它应该与 PhantomJS 。在任务 15秒 CPU c>以及过程的实际出口。

 > time gulp testem 
启动'testem'...

通过删除完成回调您在任务上设置并传递给 startCI ，它不把它作为参数，



  var testem = require（'testem' ）; 
 
 gulp.task（'test'，function（）{
 
 var testemOptions = {
 file：'testem.json'
}; 
 
 var t = new testem（）; 
 return t.startCI（testemOptions）; 
 
}）; 
  

任务按预期运行并在完成时正常退出：



 > time gulp testem 
启动'testem'... 
 ok 1 Chrome 32.0  -  sass：link 
 ok 2 Chrome 32.0  - 单元 -  HomeRoute：存在
 ok 3 Chrome 32.0  - 单元 -  HomeRoute：#model

 gulp testem 1.26s user 0.19s system 91％cpu 1.582 total 
  

$ b $顺便说一下，不知道你可以做到这一点，只需将一个带有文件属性的对象传递给 startCI ，我认为你应该使用 fs.readFile 读取配置文件，并将它的数据解析为 JSON 使用您在 testem.json 中提供的配置参数启动 testem 。

还有一件事是，有一个gulp插件， gulp-testem

a> ，我没有机会尝试，但这可能会有所帮助。

This gulp task doesn't exit after finished, I have to manually press Ctrl-C to exit.

gulp.task('test', function(done) {
    var testem = require('testem');

    var testemOptions = {
        file: 'testem.json'
    };

    var t = new testem();

    t.startCI(testemOptions, done);
});

How can i make this task exit properly?

Note: Actually it exits itself, but it takes like 15 seconds after finished.

Output:

[15:49:59] Using gulpfile ~/gulpfile.js
[15:49:59] Starting 'test'...

解决方案

Managed to reproduce your problem using the Chromium launcher, but it's should be the same with PhantomJS. There is indeed a 15sec CPU delay between the end of the task and the actual exit of the process.

> time gulp testem
Starting 'testem'...
ok 1 Chrome 32.0 - sass: link
ok 2 Chrome 32.0 - Unit - HomeRoute: exists
ok 3 Chrome 32.0 - Unit - HomeRoute: #model
ok 4 Chrome 32.0 - Unit - HomeRoute: redirect

1..4
# tests 4
# pass  4
# fail  0

# ok
Finished 'testem' after 938 ms
gulp testem  1.27s user 0.25s system 9% cpu 16.581 total

By removing the done callback you set on the task and passing to startCI that don't take this as parameter,

var testem = require('testem');

gulp.task('test', function () {

  var testemOptions = {
    file: 'testem.json'
  };

  var t = new testem();
  return t.startCI(testemOptions);

});

the task run as expected and exit properly on finish :

> time gulp testem
Starting 'testem'...
ok 1 Chrome 32.0 - sass: link
ok 2 Chrome 32.0 - Unit - HomeRoute: exists
ok 3 Chrome 32.0 - Unit - HomeRoute: #model
ok 4 Chrome 32.0 - Unit - HomeRoute: redirect

1..4
# tests 4
# pass  4
# fail  0

# ok
gulp testem  1.26s user 0.19s system 91% cpu 1.582 total

By the way, don't know you can do this, simply pass an object with a file property to startCI, I thought you should read the config file using fs.readFile and parsing its data into JSON to launch testem using the config parameters you provided inside testem.json.

One more thing, there is a gulp plugin, gulp-testem that I did not have the opportunity to try, but which may be helpful.
