如何在 Jasmine/Protractor 中模拟 angular.module('myModule', []).value() [英] How to mock angular.module('myModule', []).value() in Jasmine/Protractor
问题描述
我正在尝试使用 Protractor 的 addMockModule() 来模拟一个简单的 AngularJS 模块并覆盖一个变量:
I'm trying to use Protractor's addMockModule() to mock a simple AngularJS module and override a variable:
这是我的 HTML:
<body ng-app="myApp">
<div ng-controller="myAppController">
Overriden module value <b>{{myValue}}</b>
</div>
<script src="/Scripts/Lib/angular/angular.js"></script>
<script src="/module.js"></script>
<script src="/controller.js"></script>
</body>
这是我的控制器:
var myApp = angular.module("myApp", ['myModule']);
myApp.controller("myAppController", function ($scope, myValue) {
$scope.myValue = myValue;
});
这是我的模块:
var newModule = angular.module('myModule', []);
newModule.value('myValue', "oldValue");
这是我的 Jasmine/量角器代码:
Here is my Jasmine/Protractor code:
var mockMyModule = function () {
var newModule = angular.module('myModule', []);
newModule.value('myValue', "newMockedValue");
};
it('should override services via mock modules', function () {
ptor = protractor.getInstance();
ptor.ignoreSynchronization = true;
browser.addMockModule('portfolioDataAccessMod', mockMyModule);
browser.get('http://localhost:57627/page1.html');
expect(element(by.binding("myValue")).getText()).toBe("newMockedValue");
});
结果:
失败:
1)/AssetAllocation/Index 中的端到端测试应覆盖通过模拟模块提供服务消息:预期oldValue"为newMockedValue".
1) End-to-end test in /AssetAllocation/Index should override services via mock modules Message: Expected 'oldValue' to be 'newMockedValue'.
怎么了?
到目前为止，我发现的所有示例都是覆盖 HTTP 调用，但我只想用一个简单的变量模拟一个非常简单的模块.量角器可以吗?
All samples I have found so far are to override HTTP calls, but all I want is to mock a very simple module with a simple variable. Is it possible to do in Protractor ?
推荐答案
根据 Juliemr 在这篇文章中的说法:
According to Juliemr in this post:
https://github.com/angular/protractor/issues/509
" 在 mockedModule 中运行的代码在单独的来自测试的上下文.一个在浏览器中，一个在 node.js 中运行测试的进程"
" the code that is run in the mockedModule is run in a separate context from the test. One is in the browser, one is in the node.js process running the test "
将 mockedValue 的声明放入 it() 并启用角度同步
Put declaration of mockedValue inside it() and enable angular synchronization
it('should override services via mock modules', function () {
ptor = protractor.getInstance();
// When ignoreSynchronization is true mocking doesn't work
ptor.ignoreSynchronization = false;
browser.addMockModule('myModule', function () {
var module = angular.module('myModule').config(['$provide', function ($provide) {
$provide.constant('myValue', 'newMockedValue');
}])
});
browser.get('http://localhost:57627/page1.html');
expect(element(by.binding("myValue")).getText()).toBe("newMockedValue");
});
