由 冷暖自知 提交于 2021-02-08 14:53:41
Selenium是一个用于Web应用程序自动化测试工具。Selenium测试直接运行在浏览器中，就像真正的用户在操作一样。支持的浏览器包括IE（7, 8, 9, 10, 11），Mozilla Firefox，Safari，Google Chrome，Opera等。 主要功能包括：测试与浏览器的兼容性——测试你的应用程序看是否能够很好得工作在不同浏览器和操作系统之上。 测试系统功能——创建回归测试检验软件功能和用户需求。支持自动录制动作和自动生成 .Net、Java、Perl等不同语言的测试脚本。 Selenium也是一款同样使用Apache License 2.0协议发布的开源框架。 1、 支持平台 WebDriver支持Android和BlackBerry两个移动平台的浏览器测试。Android目前为市场占有率第一的移动平台，对于在其上面进行自动化测试，推荐Appium，Appium扩展了WebDriver的协议，支持ios平台和Android平台上的原生应用、Web应用和混合应用等。 2、支持浏览器 WebDriver 目前所支持的浏览器包括：Firefox、Chrome、IE、Edge、Opera、Safari. 为什么会选择上面几款浏览器进行支持呢？主要与浏览器的内核有关。 3、支持模式 HtmlUnit和PhantomJS是两个比较特殊的模式

由 a 夏天 提交于 2021-02-08 12:20:15
问题 This question already has an answer here : Why does {} == false throw an exception? (1 answer) Closed 3 years ago .

Keyboard shortcut to close all tabs without closing Firefox

由 佐手、 提交于 2021-02-08 11:55:25
问题 Is there a keyboard shortcut to close all open tabs without closing Firefox? In fact, I want Firefox not to close when all tabs are closed. There may be a new blank tab after all tabs are closed. 回答1: Follow the instructions in this post to configure FireFox to not close the window when the last tab is closed: (Don’t) Close Firefox with Last Tab If you hold CTRL + W all tabs will close very quickly, when the last one is closed, you will get the default tab that is there when you open FireFox.

React Redux onBlur event not firing in Safari and Firefox

由 纵然是瞬间 提交于 2021-02-08 10:16:48
问题 This seems to work perfectly in Chrome and Edge. I have a tooltip that needs to pop up onClick of the button, and then disappear onBlur. For some reason the onBlur event does not fire at all on Safari or Firefox. I've tried logging to the console in handleBlur and it does not get that far, it is as if onBlur does not exist in this context. class Tooltip extends Component { componentWillUnmount() { this.closeActiveTooltip(); } handleKeyPress = (event) => { if (event.keyCode === 27) { // Esc

Browser fingerprinting and Firefox

由 霸气de小男生 提交于 2021-02-08 10:14:56
问题 I'm wondering if there is a way to fake your browser fingerprint (can be tested on sites like https://panopticlick.eff.org/) by making the browser (firefox in my case) supply fake data? If so i would like to make an extension that does it. Is that possible? If it is any suggestions as to how would i go about doing it? Many Thanks! 回答1: Just make an extension that is a proxy and every http request that goes out would go through your extension's proxy. Then take the data and manipulate it

问题 I should be able to open a new tab in selenium for python using the code from selenium import webdriver from selenium.webdriver.common.keys import Keys driver = webdriver.Firefox() driver.get("http://stackoverflow.com/") body = driver.find_element_by_tag_name("body") body.send_keys(Keys.COMMAND + 't') But no new tab opens, and no error message appears (http://stackoverflow.com/ does load).

Chrome vs Firefox - Why do CORS headers behave differently, and how should I use them?

由 我是研究僧i 提交于 2021-02-08 03:33:08
问题 I am doing Ajax calls with CORS headers. The short version is that in Firefox, it all works nicely, in Chrome I get an error: "Refused to set unsafe header Access-Control-Request-Method" , and the same thing for Access-Control-Request-Headers. So, I am just confused. Like, very confused. What is it that I have to do in order to make CORS work properly in both Chrome and Firefox? The weird part I will say, though, is that it seems that despite the error, Chrome does execute the Ajax call. I am

Debugging: Is it possible to see value of JS variable in real time?

由 百般思念 提交于 2021-02-07 20:40:05
问题 Is there any tool (preferably extension/add-on to any browser) that allows you to see all the value changes of the desired JS variable in real time? Previously I did something like this (in pure JS): var someVariable; var previousValueOfSomeVariable; var f = function() { if (previousValueOfSomeVariable != someVariable) { console.log(Date.now(), someVariable); previousValueOfSomeVariable = someVariable; } } var TO = setInterval(f, 100); It did the trick, but was, of course, inefficient (in
