运行Karmatesting的angular度错误：HTML5模式需要一个<base>标记
我有一个Rails后端的单页Angular应用程序。 我在我的index.html文件中使用了一个标签，但是当我使用Karma运行我的前端unit testing时，我得到了以下结果：
$location in HTML5 mode requires a <base> tag to be present
我在我的主要.js文件中这样做：
angular.module('my.module').config( function($locationProvider, $routeProvider) { $locationProvider.html5Mode( true ); }
那么，有什么办法可以在业务实际呈现的页面中注入<base>元素？ 否则，在运行unit testing时告诉Angular / Karma忽略这个错误？
更新
这个Google网上论坛线程和这个GitHub问题都描述了这个问题，但是在这两种情况下，解决scheme都是简单地修改Angular的版本。 我已经这样做了，我甚至可以看到angular-mocks.js中默认的baseHref被设置的行。
这是规格问题：
describe 'amnResource', -> $compile = null $rootScope = null beforeEach -> module 'ngMock' module 'amn' module 'directive.template.cache' inject([ '$compile', '$rootScope', ($c, $r) -> $compile = $c $rootScope = $r ]) it 'compiles to an article', -> console.log $rootScope console.log $rootScope.foo $rootScope.foo = title: 'Foo' excerpt: 'foo bar qux' element = $compile('<amn-resource resource="foo"></amn-resource>')($rootScope) console.log element.html() console.log $rootScope.foo expect( element.html() ).toMatch /Foo/
噶玛输出：

您可以通过执行以下操作来禁用基本标记检查：
$locationProvider.html5Mode({ enabled: true, requireBase: false });
你可以在你的index.html <head>指定你的基本标签：
<head> <base href="/"> ... </head>

如果您不能或不想将requireBase设置为false ，则解决scheme（如其他人指出的那样）是在主HTML文件的标头中添加<base href="/"> 。 为此，您需要为Karma指定自定义HTML文件，然后您可以编辑它们。
首先查找并复制node_modules/karma/static/context.html和node_modules/karma/static/debug.html到您的unit testing文件夹，并修改两者的头文件。
然后在你的karma.conf.js中添加以下两行：
customContextFile: 'test/unit/context.html', customDebugFile: 'test/unit/debug.html',
当然你的path可能会有所不同。
