我正在尝试测试使用外部模板的指令。我尝试了以下所有解决方案，但没有成功:

• ng-directive-testing

• How to test directives that use templateUrl and controllers?

• AngularJS + Karma + Ng-html2js => Failed to instantiate module ...html

我创建了一个测试指令(一个简单的 div)并使用内联"template"和外部“templateUrl”对其进行了测试。内联解决方案有效，而外部解决方案无效:

   angular.module('AdUnit').directive('actionButton',function($location){
        return{
            scope:{
                actionName: '@'
            },
            restrict: 'E',
            //template: "<div ng-click='click()'>action button</div>",
            templateUrl: '/staticfiles/adunit/html/directives/actionButtonTemplate.html',
            controller: ['$scope', function($scope){
                $scope.click = function(){
                    $scope.$emit('ACTION_CLICK', $scope.actionName);
                }
            }]

        }
    });



    describe("Unit: Testing action button directive", function() {
    var elm, scope, linkFn;
    beforeEach(
        module('AdUnit')
    );

    beforeEach(module('/staticfiles/adunit/html/directives/actionButtonTemplate.html'));

    beforeEach(inject(function($rootScope, $compile) {
        elm = angular.element('<action-button action-name="post-action-0"></action-button>');
        scope = $rootScope;
        linkFn = $compile(elm);
        linkFn(scope);
        scope.$digest(); // have to digest to bring html from templateCache
        console.log('post compile',elm.html());// <== the html here still have {{}}
    }));

    it('should show a thumb',function() {

            console.log('post link',elm.html());// <== the html is bound

            expect(elm.text()).toBe("action button");

    });
});

我的 Karma 配置文件:

  module.exports = function(config) {
  config.set({

    // base path, that will be used to resolve files and exclude
    basePath: '',


    // frameworks to use
    frameworks: ['jasmine'],


    // list of files / patterns to load in the browser

    },

     /* ngHtml2JsPreprocessor: {

    // list of files to exclude

    colors: true,

    browsers: ['Chrome'],


    // If browser does not capture in given timeout [ms], kill it
    captureTimeout: 60000,


    // Continuous Integration mode
    // if true, it capture browsers, run tests and exit
    singleRun: false
  });
};

我不断收到以下错误:

Failed to instantiate module /staticfiles/adunit/html/directives/actionButtonTemplate.html due to:
Error: [$injector:nomod]

任何帮助将不胜感激!

编辑:@MK Safi 的回答解决了我的问题。我遗漏了以下内容:

 ngHtml2JsPreprocessor: {
     'moduleName': 'Templates',

     // Function that transforms the path to look exactly like
     // you have it in templateUrl in your Angular code
     //
     // Mine looks like this
     cacheIdFromPath: function(filepath) {
         return filepath.match(/\/staticfiles\/adunit\/html\/directives\/.*\.html/);
     }
  },

在每次测试之前:

 beforeEach(module('Templates'));

正则表达式指向与指令的“templateUrl”相同的路径很重要，因为 html2js 将使用此路径缓存这些模板(有关更多详细信息，请参阅 html2js)

最佳答案

我在测试中正确设置了此设置，您的设置看起来正确，但有几处除外。

对您的 Karma 配置文件进行以下更改:

ngHtml2JsPreprocessor = {
  'moduleName': 'Templates',

  // Function that transforms the path to look exactly like 
  // you have it in templateUrl in your Angular code
  //
  // Mine looks like this
  cacheIdFromPath: function(filepath) {
    return filepath.match(/views\/.*/)[0]
  }
}

然后在测试的 beforeEach 中包含您在上面的 Karma 配置中指定的 Templates 模块:module('Templates')

beforeEach(function() {
  module('Templates')
})

关于javascript - Angular.js 使用 html2js 将指令与外部模板联合测试 - 无法加载模板，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21074390/
