伊斯坦布爾代碼覆蓋摩卡和AngularJS

我有一個非常大的AngularJS應用程序，我使用摩卡和柴（和JSDom）測試瀏覽器。完美的作品。不過，我現在正在嘗試使用伊斯坦布爾添加代碼覆蓋範圍，並且遇到有關Angular錯誤的問題。伊斯坦布爾代碼覆蓋摩卡和AngularJS

我的測試命令：mocha src/**/*.spec.js
覆蓋命令：istanbul cover _mocha src/**/*.spec.js

，我得到的錯誤是這樣的：

TypeError: Cannot read property '1' of null 
    at Function.annotate (node_modules/angular/angular.js:3810:24) 
    at Function.angular.injector.$$annotate (node_modules/angular-mocks/angular-mocks.js:2300:36)

這是錯誤發生：https://github.com/angular/angular.js/blob/v1.4.x/src/auto/injector.js#L101。我已經登錄fnText存在和運行使用伊斯坦布爾測試時，該值是

_emoticonizeFilter_=>{__cov_OCFuCYwLZAl7nm5crSo1eg.s['7']++;emoticonizeFilter=_emoticonizeFilter_;}

我的測試：

require('../../../test-helper'); 
const expect = require('chai').expect; 

describe('filter',() => { 
    let emoticonizeFilter; 

    beforeEach(angular.mock.module('components.filters')); 
    beforeEach(inject((_emoticonizeFilter_) => { 
    emoticonizeFilter = _emoticonizeFilter_; 
    })); 

    describe('emoticonize',() => { 
    it('should replace a smiley :) with emoji ',() => { 
     expect(emoticonizeFilter('Hello :)', true)).to.equal('Hello '); 
    }); 

    it('should not replace smileys when given a falsy parameter',() => { 
     expect(emoticonizeFilter('Hello :)', false)).to.equal('Hello :)'); 
    }); 
    }); 
});

所以它打破在beforeEach，我注入_emoticonizeFilter_。伊斯坦布爾正在添加Angular不知道如何處理其註釋功能的東西。

我該如何解決這個問題？

通過從Angular 1.4.x升級到1.5.x來修復。
