Question

版本

角度：1.5.0

alertify-js：1.6.1

我想在Angular 1.5组件上实现单元测试。

我创建了我的org.apache.flume.source.twitter.TwitterSource，导入我的依赖项：

karma.conf.js

以下是将重现错误文件的测试用例的最小工作示例。它只需要进行两次测试：

//jshint strict: false
module.exports = function(config) {
    config.set({

        basePath: './',

        files: [
            'app/bower_components/jquery/dist/jquery.js',
            'app/bower_components/angular/angular.js',
            'app/bower_components/angular-ui-router/release/angular-ui-router.js',
            'app/bower_components/angular-mocks/angular-mocks.js',
            'app/bower_components/kendo-ui/src/js/kendo.ui.core.js',
            'app/bower_components/kendo-ui/src/js/kendo.angular.js',
            'app/bower_components/kendo-ui/src/js/cultures/kendo.culture.fr-FR.js',
            'app/bower_components/alertify-js/build/alertify.js',
            'app/bower_components/angular-resource/angular-resource.js',
            'app/bower_components/ui-leaflet/dist/ui-leaflet.js',
            'app/bower_components/angular-simple-logger/dist/angular-simple-logger.js',
            'app/bower_components/lodash/lodash.js',
            'app/bower_components/moment/moment.js',
            'app/bower_components/moment/locale/fr.js',
            'app/modules/app.js',
            'app/modules/**/*.md.js',
            'app/modules/**/*.js',
            'test/**/*.js'
        ],

        autoWatch: false,

        frameworks: ['jasmine'],

        browsers: ['Chrome'],

        plugins: [
            'karma-chrome-launcher',
            'karma-firefox-launcher',
            'karma-jasmine',
            'karma-junit-reporter'
        ],

        singleRun: true,

        reporters: ['dots', 'junit'],

        junitReporter: {
            outputFile: 'test-results.xml'
        }

    });
};

因为alertify我崩溃了。 We created a new dialog following the default usage of the documentation我们称之为'use strict'; describe('Component: sales', function () { var $componentController; var $scope; beforeEach(module('app.sales')); beforeEach(inject(function (_$componentController_, $rootScope, _TownshipService_, $q) { $scope = $rootScope.$new(); $componentController = _$componentController_('sales', {$scope: $scope, TownshipService: _TownshipService_}); })); describe('controller', function () { it('should be defined', function () { expect($componentController).toBeDefined(); }); it('should not crash', function () { }); }); });。

auxConfirm

我们收到以下错误消息：

(function (app) {
    'use strict';

    app.run(function () {
        alertify.dialog('auxConfirm', function () {
            // [...]
        });
    });
})(angular.module('app.component'));

通过查看alertify源代码，当它尝试注入新的自定义对话框时，我们检查自定义对话框的名称并抛出异常（如果已存在）：

Chrome 55.0.2883 (Mac OS X 10.12.2) Component: sales controller  FAILED
    Error: alertify.dialog: name already exists
    at Object.dialog ([project_folder]/ui/app/bower_components/alertify-js/build/alertify.js:2885:27)

Chrome 55.0.2883 (Mac OS X 10.12.2): Executed 2 of 2 (1 FAILED) (0.073 secs / 0.058 secs)

如何防止出现此错误？我找不到从alertify中删除自定义对话框的方法，我可以放入/** * Dialogs factory * * @param {string} Dialog name. * @param {Function} A Dialog factory function. * @param {Boolean} Indicates whether to create a singleton or transient dialog. * @param {String} The name of the base type to inherit from. */ dialog: function (name, Factory, transient, base) { // get request, create a new instance and return it. if (typeof Factory !== 'function') { return get_dialog(name); } if (this.hasOwnProperty(name)) { throw new Error('alertify.dialog: name already exists'); } }。有没有办法重新创建alertify.js来防止这种情况？

解决方案来自auxConfirm声明文件。在alertify.dialog()解决问题之前添加条件语句。

(function (app) {
    'use strict';

    app.run(function () {
        if (!alertify.auxConfirm) {
            alertify.dialog('auxConfirm', function () {
                // [...]
            });
        }
    });
})(angular.module('app.component'));
