Create a Python executable with chromedriver & Selenium

阅读更多关于 Create a Python executable with chromedriver & Selenium

问题 I have created a small web scraping app using Selenium & chromedriver for a project that outputs the content into an excel file. The people I did this app for unfortunately aren't the most tech-savvy. So my question is how can I share this app with these people? I looked into py2exe.org, but it doesn't take the chromedriver into account when creating the executable. Any better ways of doing this, without these people having to add the files manually to their "usr/bin"? 回答1: You can do this

How do I use Selenium Webdriver on headless Chrome?

阅读更多关于 How do I use Selenium Webdriver on headless Chrome?

I'm learning to use Selenium for basic things like taking a screenshot, scraping, and testing and would like to use it with headless Chrome, which is now stable as of Chrome 59. I have been able to take a screenshot using the 'selenium-webdriver' gem and chromedriver, but not headless. Here is the ruby script that I am running which hangs after starting to initialize the driver require 'rubygems' require 'selenium-webdriver' Selenium::WebDriver.logger.level = :debug p 'initializing driver' driver = Selenium::WebDriver.for :chrome, switches: %w[--headless --disable-gpu --screenshot --hide

Protractor webdriver-manager chromedriver update

阅读更多关于 Protractor webdriver-manager chromedriver update

There seems to be a issue with chromedriver 2.2 and the newest version of Chrome. This issue has to deal with the protractor not being able to send tab keys with 2.2. If I do webdriver-manager update, it does not update to the chromedriver 2.4. I did a hack where I downloaded chromedriver 2.4 exe myself and manually put it in the selenium folder, but that is not the best way to do this. How do you update protractor to use the latest version of Chromedriver 2.4? I am having the same issue as you. It is related to a new release of chrome 54. You need to wait for the next release of webdriver

I'd like to embed the Selenium ChromeDriver within a Windows Form panel. I've successfully followed this example for embedding notepad in a Windows Form. I think the problem where I am having trouble is getting the MainWindowHandle from the ChromeDriver . Here's what I've got so far: (pastebin link of full code: https://pastebin.com/RNv2vbJ1 ) //----------------------TEST--------------------- ChromeDriverService service = ChromeDriverService.CreateDefaultService(); service.HideCommandPromptWindow = true; ChromeDriver driver = new ChromeDriver(service); Console.WriteLine(driver

Selenium/Chrome/ChromeDriver Issue Preventing Crawl on VPS (DevToolsActivePort file doesn't exist)

问题 I purchased a VPS — my first ever — which is running CentOS 7 64-bit. I had absolutely zero experience with CentOS 7 until I began using this VPS today, so please go easy on me. When trying to scrape some dynamically generated content with Scrapy and Selenium, the script ultimately fails and the log throws an error that reads: DevToolsActivePort file doesn't exist On the very next line in the log, it pulls up info about the Chrome WebDriver: (Driver info: chromedriver=2.40.565383 ... Hence I

I am working on a Selenium framework using C# .net and Selenium Webdriver (with Chromedriver). I recently updated to the latest version of Chromedriver 75.0.3770.8 and now one of my lines of code is no longer working: driver.Manage().Logs.GetLog(LogType.Browser) My ChromeOptions are set as follows: options.SetLoggingPreference(LogType.Browser, LogLevel.Severe); None of this has changed - the only update I've made is to Chromedriver 75. If I revert back to Chromedriver 74 then this code works again. Currently it is failing with "object reference not set to an instance of an object". The release

问题 I have built a Polymer based application. I'd like to write some end-to-end tests (not unit tests, but user behavior integration tests) for it. How do I do this currently (May 2015)? 回答1: I spent the past few days looking into this problem.

Hope this is useful for those looking to write end-to-end
