运行 Karma 测试时出现角度错误:HTML5 模式需要 <base>标签 [英] Angular error running Karma tests: HTML5 mode requires a <base> tag

问题描述

我有一个带有 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 运行我的前端单元测试时，我得到了这个:

I have a single-page Angular app with a Rails backend. I am using a tag in my index.html file, but when I run my front-end unit tests using Karma, I get this:

$location in HTML5 mode requires a <base> tag to be present

我在我的主 .js 文件中执行此操作:

I am doing this in my main .js file:

angular.module('my.module').config( function($locationProvider, $routeProvider) {
  $locationProvider.html5Mode( true );
}

那么，有什么方法可以在 karma 实际呈现的页面中注入 元素?或者，告诉 Angular/Karma 在运行单元测试时忽略这个错误?

So, is there any way I can inject a <base> element in the page that karma actually renders? Or else, tell Angular/Karma to ignore this error when running unit tests?

此 Google 网上论坛帖子和this GitHub issue 都描述了这个问题，但在这两种情况下，解决方案都是简单地提高 Angular 的版本.我已经这样做了，我什至可以在 angular-mocks.js 中看到设置默认 baseHref 的行...

This Google Groups thread and this GitHub issue both describe this problem but in both cases the solution is to simply bump up the version of Angular. I've done that and I can even see the line in angular-mocks.js where the default baseHref gets set...

这是有问题的规范:

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/

业力输出:

推荐答案

您可以通过执行以下操作来禁用基本标签检查:

You can disable the base tag check by doing the following:

$locationProvider.html5Mode({
  enabled: true,
  requireBase: false
});
