Selenium不再推荐使用PhantomJS，会报如下警告 UserWarning: Selenium support for PhantomJS has been deprecated, please use headless versions of Chrome or Firefox instead warnings.warn('Selenium support for PhantomJS has been deprecated, please use headless ' 于是从PhantomJS转移到Chrome，使用headless versions of Chrome时，首先要安装Chrome，然后下载chromedriver，再把chromedriver的地址配置到系统环境变量path中，方便调用。如果不把chromedriver的地址配置到系统环境变量的话，也可以在使用时指定chromedriver的地址。注意Chrome和chromedriver有版本对应的要求，系统中安装了某一版本的chrome要使用对应版本的chromedriver，其实下载最新版本的Chrome和chromedriver就行了，一般都是对应的。 Chrome下载地址：https://chrome.en.softonic.com/ chromedriver下载地址：http://npm

Karma, PhantomJS and es6 Promises

阅读更多关于 Karma, PhantomJS and es6 Promises

问题 I am writing a JavaScript library that uses the new es6 promises. I can test the library in Firefox because promises are defined. However, when I try to test my code with Karma and PhantomJS, I get the error Can't find variable: Promise. . I am guessing this is because the PhantomJS browser doesn't support es6 promises yet. How can I configure Karma to bring in the polyfill for promises? 回答1: You can pull in the Babel polyfill by simply installing Babel Polyfill: npm install --save-dev babel

win10无法运行phantomjs

@参考文章 echarts利用phantomjs将图片保存到电脑，在win7下好好的，在win10下报错： 'phantomjs' 不是内部或外部命令，也不是可运行的程序或批处理文件。在win7下没有配置环境变量，在win10下需要配置环境变量。虽然我win10账有管理员权限，配置系统环境变量仍不起作用。最后在用户环境变量配置成功。配置到phantomjs的bin目录即可来源： https://www.cnblogs.com/yanan7890/p/11790693.html

I have a unit test that is passing when I run it via python manage.py test , but failing when I run it from within PyCharm. def test_alpha(self): from selenium.webdriver.common.utils import free_port from selenium import webdriver driver = webdriver.PhantomJS(executable_path=PHANTOMJS_PATH, port=free_port()) driver.quit() The exception I get when running from PyCharm is WebDriverException: Message: 'Can not connect to GhostDriver' I've spent a fair amount of time digging into this problem, and I've noticed that when I specify a port manually the test passes within PyCharm. # suppose 50000

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I'm using Phantomjs to detect errors/warnings on my pages by hooking console messages : page.onConsoleMessage = function(msg, line, source) { console.log(msg); } page.open(page.address, function (status) { if (status !== 'success') { console.log('Fail to load the address'); } else { for(var i=0;i<page.errors.length;i++) { console.log(page.errors[i]); } } phantom.exit(); }); It works fine with the errors, but it does not record the warnings. By errors and warnings, I mean what Chrome console displays in red/yellow. Is there a way to do it in

I'm very new to Angular and I'm trying to figure much of this out still. I'm writing some tests using Angular 1.5.8 which I generated from the Yeoman Generator. Specifically, I'm trying to figure out how to manipulate $httpBackend results (I'm not sure if that's important or not)... In my app.js file I have the following code: .run(['$rootScope', '$location', 'breadcrumbService', function ($rootScope, $location, breadcrumbService) { $rootScope.$on('$viewContentLoaded', function () { jQuery('html, body').animate({scrollTop: 0}, 200); }); $rootScope.isEditMode = false; $rootScope.$on('

How to reduce phantomjs memory consumption?

阅读更多关于 How to reduce phantomjs memory consumption?

问题 I'm using phantomjs with casperjs to run multiple tests and it looks like each instance of PhantomJS takes ~106M of RAM. Is it possible to reduce that amount? Is there a simple way to run tests in multiple "tabs"? 回答1: Edit: As pointed by @newfurniturey, release is now deprecated. We must use close : http://phantomjs.org/api/webpage/method/close.html Don't know if that helps, but the release function could be a good tail : http://phantomjs.org/api/webpage/method/release.html Releases memory
