带有 phantomjs 的量角器永远挂起
Protractor with phantomjs hangs forever
这是我的配置文件:
exports.config = {
seleniumServerJar: './selenium-server-standalone-2.43.1.jar',
"capabilities": {
"browserName": "phantomjs"
},
specs: [
"test.js"
],
jasmineNodeOpts: {
isVerbose: false,
showColors: true,
includeStackTrace: true
},
};
这是所谓的 test.js。它是针对 ng-europe
社区站点的,所以每个愿意的人都可以 运行 this.I 选择它来学习量角器写成 angular:
describe('test ng-europe', function() {
beforeEach(function() {
browser.get('http://ngeurope.org');
});
it('should have a title', function() {
expect(browser.getTitle()).toContain('ng-europe');
element.all(by.repeater('avatar in talk.avatars')).count().then(function(count) {
console.log(count);
});
});
it('search something', function() {
var search_=element(by.model('speakerq'));
var speakers_=element.all(by.repeater('speaker in config.speakers').column('name'));
var speakers = $$('div.speaker.col-xs-12.col-sm-4.text-center.ng-scope img.img-responsive.img-thumbnail.img-circle.avatar');
search_.sendKeys('igor');
expect(speakers.count()).toBe(1);
console.log("speakers count" + speakers.count());
});
it('search something else', function() {
var search_=element(by.model('talksq'));
var talkers = $$('ul.list-unstyled li.ng-scope.ng-binding span.speakers-names.ng-binding');
search_.sendKeys('with');
expect(talkers.count()).toBe(8);
console.log("talkers count" + talkers.count());
});
it('click on jobs', function() {
var jobs_button=element(by.linkText('Jobs'));
jobs_button.click();
var sponsors=$$('div.col-md-4 img.sponsor-logo.gold-sponsor')
expect(sponsors.count()).toBe(4);
});
});
我是这样称呼它的:
>protractor conf.js
selenium驱动在同一目录节点,%appdata%\npm在路径,phantomjs已安装,updated.Everything 运行没问题如果我将驱动程序设置为 chrome 或 firefox 但使用 phantomjs 脚本就会挂起永远不会显示 happens.No 错误,nothing.Just 这个:
Starting selenium standalone server...
[launcher] Running 1 instances of WebDriver
Selenium standalone server started at http://XX.XX.XXX.XX:60324/wd/hub
我错过了什么?
我至少成功地 运行 通过了测试:
phantomjs
1.9.7
protractor
2.0.0
但是,现在它在成功通过第一个 it()
块后立即抛出以下错误消息:
Error: Failed: Error communicating with the remote browser. It may have died.
这是我使用的配置(应用了几个 phantomjs 助手 "tricks"):
exports.config = {
seleniumArgs: ['-browserTimeout=60'],
"capabilities": {
"browserName": "phantomjs",
'phantomjs.cli.args': [
'--ignore-ssl-errors=true',
'--web-security=false'
]
},
specs: [
"test.js"
],
framework: "jasmine2",
allScriptsTimeout: 20000,
onPrepare: function () {
browser.driver.manage().window().maximize();
},
jasmineNodeOpts: {
showColors: true,
isVerbose: true,
includeStackTrace: true,
defaultTimeoutInterval: 25000
}
};
有很多人问如何解决这样的错误:
有不同的解决方法建议,但 none 对我和其他人都有效。
这引出了答案的要点:为什么首先使用 phantomjs?
正如 protractor
developers 所述:
We recommend against using PhantomJS for tests with Protractor. There
are many reported issues with PhantomJS crashing and behaving
differently from real browsers.
延长点。
如果使用 protractor
的主要目的是端到端测试,那么您绝对应该重新考虑您的浏览器选择。端到端测试应该模仿您的应用程序的真实用户,我敢肯定,他不会使用 phantomjs
来浏览您的站点。
如果选择phantomjs
的原因是没有真实显示,可以借助xvfb
使用虚拟显示(查看更多here) or run your tests on a remote selenium server, either your own, or provided by BrowserStack
or Sauce Labs
.
