内容图文
我经历过各种职位,但找不到解决方案.
HTML：
<div class="col-xs-3" ng-repeat="post in posts track by $index">
<div class="well">
<h3 class="postTitle">
<a ui-sref="singlePost({id:post.id,permalink:post.permalink})">
{{post.title}}
</a>
</h3>
<h5>By: {{post.author}} | {{post.datePublished}}</h5>
</div>
</div>
censing.js：
'use strict';
/* https://github.com/angular/protractor/blob/master/docs/toc.md */
describe('The Single Page Blogger E2E Test', function() {
var ptor = browser; // browser === protractor.getInstance();
// ptor.get('/'); //go to http://localhost:8000
beforeEach(function() {
ptor.get('app');
});
it('Should have 4 posts', function() {
var posts = element.all(by.repeater('post in posts'));
expect(posts.count()).toBe(4); // we have 4 hard coded posts
});
it('Should redirect to #/posts/1/sample-title1', function() {
var posts = element.all(by.repeater('post in posts'));
posts.first().then(function(postElem) {
postElem.findElement(by.tagName('a')).then(function(a) {
a.click(); //click the title link of 1st post
expect(ptor.getCurrentUrl()).toMatch('/posts/1/simple-title1');
});
});
});
});
protractor.conf.js：
exports.config = {
allScriptsTimeout: 11000,
specs: [
'specs/*.js'
],
capabilities: {
'browserName': 'chrome'
},
baseUrl: 'http://localhost:8000',
framework: 'jasmine2',
jasmineNodeOpts: {
onComplete: null,
isVerbose: true,
showColors: true,
includeStackTrace: true,
defaultTimeoutInterval: 30000
}
};

第22:19行在posts.first().then(function(postElem){});中指向.
我不了解代码中的错误,因为我已经在堆栈溢出帖子之一中以及通过量角器api指南检查了代码,我们可以将first()链接起来,然后<--这样.谁能帮我这个忙吗？
解决方法:
发生了重大变化.没有element.then() since 2.0.0.
改用：
posts.first().element(by.tagName('a')).click();
expect(browser.getCurrentUrl()).toMatch('/posts/1/simple-title1');
