在 step 3 of the AngularJS Tutorial AngularJS 教程示例建议添加另一个 e2e 测试:
it('should display the current filter value within an element with id "status"',
function() {
expect(element('#status').text()).toMatch(/Current filter: \s*$/);
input('query').enter('nexus');
expect(element('#status').text()).toMatch(/Current filter: nexus\s*$/);
//alternative version of the last assertion that tests just the value of the binding
using('#status').expect(binding('query')).toBe('nexus');
});
测试最初失败，将以下内容添加到页面应该可以使其通过。添加后我的页面是这样的:
<!doctype html>
<html lang="en" ng-app ng-controller="PhoneListCtrl">
<head>
<meta charset="utf-8">
<title ng-bind-template="Google Phone Gallery: {{query}}">Google Phone Gallery</title>
<link rel="stylesheet" href="css/app.css">
<link rel="stylesheet" href="css/bootstrap.css">
<script src="lib/angular/angular.js"></script>
<script src="js/controllers.js"></script>
</head>
<body ng-controller="PhoneListCtrl">
<div class="container-fluid">
<div class="row-fluid">
<div class="span2">
<!--Sidebar content-->
Search:
<input ng-model="query">
<div id="status">
Current filter: {{query}}
</div>
</div>
<div class="span10">
<!--Body content-->
<ul class="phones">
<li ng-repeat="phone in phones | filter:query">
{{phone.name}}
<p>
{{phone.snippet}}
</p>
</li>
</ul>
</div>
</div>
</div>
</body>
最终断言失败了:`
using('#status').expect(binding('query')).toBe('nexus');`
带有以下消息:
Chrome 23.0 PhoneCat App Phone list view should display the current filter value within an element with id "status" FAILED
expect select binding 'query' toBe "nexus"
我认为这是因为该元素实际上并未绑定(bind)到查询，元素的内容使用该绑定(bind)，但是，我应该做什么才能使其通过？

编辑:Controllers.js
'use strict';
/* Controllers */
function PhoneListCtrl($scope) {
$scope.phones = [
{"name": "Nexus S",
"snippet": "Fast just got faster with Nexus S.",
"age": 0},
{"name": "Motorola XOOM™ with Wi-Fi",
"snippet": "The Next, Next Generation tablet.",
"age": 1},
{"name": "MOTOROLA XOOM™",
"snippet": "The Next, Next Generation tablet.",
"age": 2}
];
$scope.orderProp = 'age';
}
最佳答案
我发现您使用了两次 ng-controller="PhoneListCtrl"。这可能会导致问题。删除 html 标记上的一个。
