How do I switch to the active tab in Selenium?

阅读更多关于 How do I switch to the active tab in Selenium?

问题 We developed a Chrome extension, and I want to test our extension with Selenium. I created a test, but the problem is that our extension opens a new tab when it's installed, and I think I get an exception from the other tab. Is it possible to switch to the active tab I'm testing? Or another option is to start with the extension disabled, then login to our website and only then enable the extension. Is it possible? Here is my code: def login_to_webapp(self): self.driver.get(url='http://example

问题 Specifically, I'm evaluating all of the images on a page to see if they have a certain attribute, and then adding some new <divs> to the DOM based on those attributes. Must I wait for document.ready to fire before performing these modifications in order to be guaranteed that Chrome has loaded all of the necessary pieces of the DOM? The problem I'm running into is that sometimes document.ready takes a short while to fire and the user is already browsing around the page, wondering why my

问题 I'm creating a UserScript extension for Firefox & Chrome and I'm trying to use some of the code in the website's JavaScript, e.g.: function: myFunction(){ return Grooveshark.playNextSong(); } The problem is when I test this code, Grooveshark is a null reference. I know there are other people who have done it: see BetterGrooveshark But I don't know why my simple extension can't call Grooveshark's JavaScript functions. Do I need to 'append' my script to the document in order for this to work?:

问题 Is Chrome blocking access to the webstore url? I would like to make an extension that displays a like button beside the +1 button, but it looks like that content scripts are not working on https://chrome.google.com/webstore/* Is that true? 回答1: TL;DR The webstore cannot be scripted by extensions, and the flag that previously allowed you to do that ( --allow-scripting-gallery ) has been removed in Chrome 35. Chrome extensions cannot execute Content scripts / insert CSS the Chrome Web Store.

Detect Chrome extension first run / update

阅读更多关于 Detect Chrome extension first run / update

问题 How can an extension find out that it is being run for the first time or has just been updated, so that the extension can perform some specific actions? (e.g. open a help page or update settings) 回答1: In newer versions of Chrome (since Chrome 22), you can use the chrome.runtime.onInstalled event, which is much cleaner. Example: // Check whether new version is installed chrome.runtime.onInstalled.addListener(function(details){ if(details.reason == "install"){ console.log("This is a first

问题 I have a Greasemonkey script that works just fine in Firefox and Opera. I struggle with getting it to work in Chrome, however. The problem is injecting a function into the page that can be invoked by code from the page. Here's what I'm doing so far: First, I get a helper reference to the unsafeWindow for Firefox. This allows me to have the same code for FF and Opera (and Chrome, I thought). var uw = (this.unsafeWindow) ? this.unsafeWindow : window; Next, I inject a function into the page. It
