伊斯坦布尔代码覆盖摩卡和AngularJS

问题描述：

我有一个非常大的AngularJS应用程序，我使用摩卡和柴（和JSDom）测试浏览器。完美的作品。不过，我现在正在尝试使用伊斯坦布尔添加代码覆盖范围，并且遇到有关Angular错误的问题。伊斯坦布尔代码覆盖摩卡和AngularJS

我的测试命令：mocha src/**/*.spec.js
覆盖命令：istanbul cover _mocha src/**/*.spec.js

，我得到的错误是这样的：

TypeError: Cannot read property '1' of null 
    at Function.annotate (node_modules/angular/angular.js:3810:24)

这是错误发生：https://github.com/angular/angular.js/blob/v1.4.x/src/auto/injector.js#L101。我已经登录fnText存在和运行使用伊斯坦布尔测试时，该值是

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

我的测试：

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_。伊斯坦布尔正在添加Angular不知道如何处理其注释功能的东西。

我该如何解决这个问题？

答

通过从Angular 1.4.x升级到1.5.x来修复。
