单元测试一个指令,其模板都是带有脚本标签的文件

Question

我很难搞清楚如何在我的Karma单元测试中包含我的指令模板(这些模板都在不同脚本标签中的一个文件中).

我得到的错误:

PhantomJS 1.9 (Linux) ERROR
 SyntaxError: Parse error
 at /var/www/html/tweak/core/global/views/js/modules/datable/templates.html:1
PhantomJS 1.9 (Linux): Executed 0 of 0 ERROR (0.313 secs / 0 secs)

以下是代码的相关部分:

我的指示肉:

return {
  scope       : {
    columns : '=',
    config  : '='
  },
  templateUrl : 'datable/table.html',
  restrict    : 'E',
  controller  : 'datableCtrl',
  link        : linkingFunction
};

我的模板文件:

<script type="text/ng-template" id="datable/table.html">
  <!-- data rows -->
  <tr
    ng-repeat="row in rows track by $id($index)"
    class="datable-row"
    ng-hide="loading">

    <td
      ng-repeat="column in columns track by $id($index)"
      ng-class="{'edit-on': editMode == 'on'}"
      class="{{column.classes.join(' ') + ' column' + $index}}"
      ng-style="column.style">

      <div ng-include="editMode == 'on' && column.editable
        ? 'datable/editCell.html'
        : 'datable/normalCell.html'">
      </div>
    </td>

    <!-- save button -->
    <td ng-show="editMode == 'on'" style="width:1px;">
      <button class="btn"> Save </button>
    </td>
    <!-- / save button -->

  </tr>
  <!-- / data rows -->
</script>

<script type="text/ng-template" id="datable/editCell.html">
  <div ng-switch="column.inputType">

    <!-- text input -->
    <div ng-switch-when="text">
      <div ng-class="{
        'input-append'  : column.append != '',
        'input-prepend' : column.prepend != ''
      }">

        <span
          class="add-on"
          ng-show="column.prepend"> {{column.prepend}} </span>

        <input
          type="text"
          ng-model="row[column.model]"
          ng-keydown="query()"
          ng-class="inputClass.join(' ')"
          ng-attrs="column.inputAttrs">

        <span
          class="add-on"
          ng-show="column.append"> {{column.append}} </span>
      </div>
    </div>
    <!-- end text input -->

    <!-- select input -->
    <div ng-switch-when="select">
      <select
        ng-model="row[column.model]"
        ng-change="query()"
        ng-options="item.value as item.name for item in column.options"
        ng-class="inputClass.join(' ')"
        ng-attrs="column.inputAttrs">

        <option value=""> -- </option>
      </select>
    </div>
    <!-- end select -->

    <!-- radio / checkbox -->
    <div ng-switch-default>
      <label ng-repeat="(key, value) in column.options track by $id($index)">
        <input
          type="{{column.inputType}}"
          ng-class="inputClass.join(' ')"
          ng-change="query()"
          value="{{key}}"
          ng-checked="row[column.model].indexOf('key') > -1"
          ng-attrs="column.inputAttrs">

        <span> {{value}} </span>
      </label>
    </div>
    <!-- end radio / checkbox -->

  </div>
</script>

<script type="text/ng-template" id="datable/normalCell.html">
  <div class="read-only">
    <span> {{column.prepend}} </span>
    <!-- <span> {{row[column.model] | datableFilter : column.filter}} </span> -->
    <span ng-bind-html-unsafe="(row[column.model] + '') | datableFilter : column.filter"></span>
    <span> {{column.append}} </span>
  </div>
</script>

我的单元测试:

'use strict'

describe("datable", function() {

  describe('directive', function () {
    var $rootScope, $compile, element;

    beforeEach(module('datable'));
    beforeEach(module('/var/www/html/tweak/core/global/views/js/modules/datable/templates.html'));

    beforeEach(inject(function (_$rootScope_, _$compile_) {
      $rootScope = _$rootScope_;
      $compile = _$compile_;

      $rootScope.tableConfig = {
        editable     : true
      };
      $rootScope.columns = [];

      element = angular.element('<datable config="tableConfig" columns="columns"></datable>');

        $compile(element)($rootScope);
        $rootScope.$digest();
    }));

    it('should have ng-scope class', function() {
        expect(element.hasClass('ng-scope')).toBe(true);
    });
  });
});

basePath = '/var/www/html/' + branch + '/';

Answer 1

我认为您的错误是因为您尝试将HTML文件加载到通常接受javascript的文件列表中.我确实有一个解决方案.

在我开始之前,我有业力0.10.2,看起来你是在0.8.x或以下？我有这个在0.10.2工作,但我无法安装0.8.x. 我会尝试翻译0.8.x,但无法测试我在做什么,所以我将主要用0.10.x来描述.如果你有能力的话,可能更容易转移到最新的业力.

配置

0.10.x

外部HTML部分可以由karma-ng-html2js-preprocessor加载.这通常用于通过templateUrl类似的方法直接加载到指令中.在0.10.2中,您需要确保安装此软件包(使用npm),然后在您的karma配置中包含以下内容:

preprocessors: {
    '**/*.html' : ['ng-html2js']
},

ngHtml2JsPreprocessor: {
    cacheIdFromPath: function(filepath) {
        // If you had more than one html file you would want to do something more clever here.
        return 'inlinetemplates';
    },
    moduleName: 'inlinetemplates'
},

plugins: [
    ...,
    'karma-ng-html2js-preprocessor'
],

files: [
    ...,
    'app/alltemplates.html', // your main template html
    // Don't include paths for individual files that are inlined in the file above
]

这将允许您加载一个模块,module('inlinetemplates')该模块将插入主模板文件(而不是单个模板)的内容$templateCache.

0.8.4

因此,翻译为0.8.x ...我认为你需要使用html2js哪个不是那么强大,但是在这个版本中包含在业力中.您不需要在插件中安装或包含它,也无法配置它的使用方式,因此您只需要

preprocessors = { '**/*.html': ['html2js'] }

创建的模块及其插入的项目$templateCache将使用您用于引用主模板html的路径命名.

使用Javascript

0.10.x

现在,您应该能够加载相关模块并使用以下权限访问主模板文件的内容

var templates = $templateCache.get('inlinetemplates')

剩下要做的就是将内联模板从主模板文件内容推送到$templateCache.这是使用angular script指令完成的,所以我们只需要编译/链接我们用angular加载的文件.你可以非常简单地做到这一点

$compile(templates)(scope);

因此,将这些放在一起,您可以在describe需要加载模板的任何块中包含以下内容.

beforeEach(module('inlinetemplates'));
beforeEach(inject(function($compile, $templateCache, $rootScope) {
    var templatesHTML = $templateCache.get('inlinetemplates');
    $compile(templatesHTML)($rootScope);
}));

0.8.4

var mainTemplateLocation = 'path/used/to/refer/to/main/templates/in/karma/conf.html';
beforeEach(module(mainTemplateLocation));
beforeEach(inject(function($compile, $templateCache, $rootScope) {
    var templatesHTML = $templateCache.get(mainTemplateLocation);
    $compile(templatesHTML)($rootScope);
}));

加起来

同样,我无法保证0.8.x指令可以正常工作,特别是没有调整,但这肯定适用于0.10.x.

Karma已经拥有将外部HTML部分推送到您的测试中的功能,所有缺少的功能都是能够正确地解释您的主模板.
