PhantomJS不支持Javascript Internationalization API [英] Javascript Internationalization API is not supported by PhantomJS

问题描述

我对使用ECMAScript Internationalization API的 AngularJs 服务运行了一系列 Jasmine 测试。当我通过Chrome运行它们时，它们都成功运行。但是，当我使用 PhantomJS 通过maven运行它们时，它们都会失败，因为它似乎 PhantomJs 不支持Internationalization API然而。

I have series of Jasmine tests running against an AngularJs service that uses ECMAScript Internationalization API. They all run successfully when I run them through Chrome. However, when I use PhantomJS to run them through maven, they all fail as it seems PhantomJs does not support Internationalization API yet.

我使用Intl对象获得的测试错误信息是：

The error message I get for the tests using Intl object is :

1：ReferenceError：找不到变量：localService.js中的Intl

1: ReferenceError: Can't find variable: Intl in localizationService.js

其余的测试都失败了。

And the rest of the tests just fail.

测试很简单，看起来像这样：

The tests are simple and look like this:

it('Format date with en-us locale', (function (){
    var date= "06/13/2013"
    expect(service.date(date,'en-us')).toEqual("6/13/2013");
}))

以及方法service（localizationService.js）是Intl API的简单包装器：

and the methods in service (localizationService.js) are simple wrappers around Intl API:

function getCurrentTimeZone(){
    return Intl.DateTimeFormat().resolved.timeZone
}

function date(dateInput,locale,options){
        // some other stuff
        // ... 
        if (locale) {
            return _date.toLocaleDateString(locale,options);
        } else {
            return _date.toLocaleDateString();
        }
}

我的问题是：

1-我的假设是否正确 PhantomJS v1.9.2 不支持 ECMAScript国际化API ？无论如何要确认吗？

1- Is my assumption correct that PhantomJS v1.9.2 does not support ECMAScript internationalization API? Is there anyway to confirm that?

2-如何解决此问题？我需要通过maven运行我的测试，我将有更多测试以某种方式触及我的本地化服务API。

谢谢

2- How can I approach resolving this issue? I need to run my tests through maven and I will have more tests hitting my localizationService API one way or the other.
Thanks

推荐答案

不确定您是否使用了Karma，但这是我必须采取的措施来解决同样的问题。

Not sure if you're using Karma or not, but here's what I had to do to fix the same issue.

1. npm install karma-intl-shim --save-dev

这也将安装polyfill库Intl;

This will also install the polyfill library Intl;

将'intl-shim'添加到karma.conf.js中的frameworks集合中：

Add 'intl-shim' to the frameworks collection in karma.conf.js:

...
frameworks: ['intl-shim'],

在karma.conf.js中添加您要测试的语言环境文件，例如'en-US'：

Add the locale file you wish to test with in karma.conf.js, for example 'en-US':

...
files: [
      './node_modules/Intl/locale-data/jsonp/en-US.js',
...
