How to implement chromedriver in selenium in Linux platform

Can somebody tell me how to use the Chrome driver in Selenium for Linux platform? I have my chrome driver location at username/home/chromedriver . My code is:

System.setProperty("webdriver.chrome.driver", "/home/username/ChromeDriver/chrome‌​driver"); driver = new ChromeDriver(); driver.get("facebook.com"); 

org.openqa.selenium.WebDriverException : Unable to either launch or connect to Chrome. Please check that ChromeDriver is up-to-date. Using Chrome binary at: /opt/google/chrome/google-chrome (WARNING: The server did not provide any stacktrace information)

The location of your Chrome driver ( username/home/chromedriver ) and your configuration ( /home/username/ChromeDriver/chrome‌​driver ) don’t match. Make sure you use the right path at every location. Apart from this, everything should be ok, this is how I initialize mine Chrome, too. Try re-downloading all the parts once again. Don’t forget to unzip the chromedriver package.

Requirements

The ChromeDriver controls the browser using Chrome’s automation proxy framework.

The server expects you to have Chrome installed in the default location for each system:

OS Expected Location of Chrome ------------------------------------- Linux /usr/bin/google-chrome Mac /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome Windows XP %HOMEPATH%\Local Settings\Application Data\Google\Chrome\Application\chrome.exe Windows Vista C:\Users\%USERNAME%\AppData\Local\Google\Chrome\Application\chrome.exe 

For Linux systems, the ChromeDriver expects /usr/bin/google-chrome to be a symlink to the actual Chrome binary. See also the section on overriding the Chrome binary location.

Getting Started

To get set up, first download the appropriate prebuilt server. Make sure the server can be located on your PATH or specify its location via the webdriver.chrome.driver system property. Finally, all you need to do is create a new ChromeDriver instance:

WebDriver driver = new ChromeDriver(); driver.get("http://www.google.com"); 

Therefore, download the version of chromedriver you need, unzip it somewhere on your PATH (or specify the path to it via a system property), then run the driver.

Установка драйвера chromedriver для Chrome Selenium

Для запуска тестов Selenium в Google Chrome, помимо самого браузера Chrome, должен быть установлен ChromeDriver. Установить ChromeDriver очень просто, так как он находится в свободном доступе в Интернете. Загрузите архив в зависимости от операционной системы, разархивируйте его и поместите исполняемый файл chromedriver в нужную директорию.

Какую версию chromedriver установить?

Мы должны установить именно ту версия которая была бы совместима с установленным Google Chrome на нашем ПК или VDS. В случае, если версии не совпадают, то мы получим данную ошибку:

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 81

Введите в адресную строку Google Chrome данный путь:

У вас появится вот такое окно:

Рисунок 1 — Узнаем версию браузера Google Chrome

Скачать ChromeDriver для Linux, Windows и Mac

На данный момент актуальная версия драйвера 81.0.40 хотя у меня установлен более старый Google Chrome и последняя версия мне не подойдет. Как видно на рисунке выше, мне нужна версия 79.0.39 у вас может быть другая версия, нужно её скачать.

Рисунок 2 — Официальный сайт Google для загрузки драйвера chromedriver

На момент прочтения этой статьи версия может быть другой. Всегда выбирайте более новую версию, чтобы не поймать старые баги которые уже давно исправили в новой версии. НО! Помните, что вам нужно обновить и свой браузер Google Chrome если вы хотите работать с новой версией ChromeDriver.

Установка ChromeDriver под Linux, Windows и Mac

1. Заходим на сайт https://chromedriver.storage.googleapis.com/index.html?path=79.0.3945.36/ (Проверьте сайт с Рис. 2 на обновления, тут версия: 79.0.3945);
2. Скачиваем архив под вашу операционную систему;
3. Распаковываем файл и запоминаем где находится файл chromedriver или chromedriver.exe (Windows).

Рисунок 3 — Скаченный архив с ChromeDriver

Если у вас Linux дистрибутив или Mac, вам нужно дать файлу chromedriver нужные права на выполнения. Открываем терминал и вводим команды одна за другой.

Developed in collaboration with the Chromium team, ChromeDriver is a standalone server which implements WebDriver’s wire protocol.

The ChromeDriver consists of three separate pieces. There is the browser itself («chrome»), the language bindings provided by the Selenium project («the driver») and an executable downloaded from the Chromium project which acts as a bridge between «chrome» and the «driver». This executable is called «chromedriver», but we’ll try and refer to it as the «server» in this page to reduce confusion.

The server expects you to have Chrome installed in the default location for each system:

OS	Expected Location of Chrome
Linux	/usr/bin/google-chrome 1
Mac	/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome
Windows XP	%HOMEPATH%\Local Settings\Application Data\Google\Chrome\Application\chrome.exe
Windows Vista and newer	C:\Users\%USERNAME%\AppData\Local\Google\Chrome\Application\chrome.exe

1 For Linux systems, the ChromeDriver expects /usr/bin/google-chrome to be a symlink to the actual Chrome binary. See also the section on overriding the Chrome binary location .

• Mac users with Homebrew installed: brew install —cask chromedriver
• Debian based Linux distros: sudo apt-get install chromium-driver
• Windows users with Chocolatey installed: choco install chromedriver

Running ChromeDriver as a standalone process

Since the ChromeDriver implements the wire protocol, it is fully compatible with any RemoteWebDriver client. Simply start up the ChromeDriver executable (that works as a server), create a client, and away you go:

WebDriver driver = new RemoteWebDriver("http://localhost:9515", DesiredCapabilities.chrome()); driver.get("http://www.google.com"); 

If you are using the RemoteWebDriver and you get the The path to the chromedriver executable must be set by the webdriver.chrome.driver system property error message you likely need to check that one of these conditions is met:

• The chromedriver binary is in the system path, or
• The Selenium Server was started with -Dwebdriver.chrome.driver=c:\path\to\your\chromedriver.exe

ChromeDriver user documentation provides more information on the known issues and workarounds.

Check if the bug has been reported yet. If it hasn’t, please open a new issue and be sure to include the following:

• What platform are you running on?
• What version of the chromedriver are you using?
• What version of Chrome are you using?
• The failure stacktrace, if available.
• The contents of chromedriver’s log file (chromedriver.log).

Of course, if your bug has already been reported, you can update the issue with the information above. Having more information to work on makes it easier for us to track down the cause of the bug.

Testing earlier versions of Chrome

ChromeDriver is only compatible with Chrome version 12.0.712.0 or newer. If you need to test an older version of Chrome, use Selenium RC and a Selenium-backed WebDriver instance:

URL seleniumServerUrl = new URL("http://localhost:4444"); URL serverUnderTest = new URL("http://www.google.com"); CommandExecutor executor = new SeleneseCommandExecutor(seleniumServerUrl, serverUnderTest, DesiredCapabilities.chrome()); WebDriver driver = new RemoteWebDriver(executor);

Setup Selenium with Python and Chrome Driver on Ubuntu & Debian

Selenium is a versatile tool that can be used for automating browser-based tests. It has a wide range of features that make it an ideal choice for automating tests. Selenium can be used to automate tests for web applications and web services. Selenium supports a number of programming languages, including Java, C#, Python, and Ruby.

This makes it possible to write tests in the language that you are most comfortable with. In addition, Selenium has a large user community that provides support and help when needed.

In this blog post, you will learn to set up a Selenium environment on an Ubuntu system. Also provides you with a few examples of Selenium scripts written in Python.

Prerequisites

You must have Sudo privileged account access to the Ubuntu system.

One of the examples also required a desktop environment to be installed.

Step 1: Installing Google Chrome

Use the below steps to install the latest Google Chrome browser on Ubuntu and Debian systems.

First of all, download the latest Gooogle Chrome Debian package on your system.

wget -nc https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb 

sudo apt update sudo apt install -f ./google-chrome-stable_current_amd64.deb 

This will complete the Google Chrome on your Ubuntu or Debian system. This will also create an Apt PPA file for further upgrades.

Step 2: Installing Selenium and Webdriver for Python

We will use a virtual environment for running Python scripts. Follow the below steps to create Python virtual environment and install the required python modules.

Create a directory to store Python scripts. Then switch to the newly-created directory.

python3 -m venv venv source venv/bin/activate 

Once the environment is activated, You will find the updated prompt as shown below screenshot:
Now use PIP to install the selenium and webdriver-manager Python modules under the virtual environment.

pip install selenium webdriver-manager 

Example 1: Selenium Python Script with Headless Chrome

Your system is ready to run Selenium scripts written in Python. Now, create a sample selenium script in Python that fetches the title of a website.

This script will run headless, So you can run it without an X desktop environment. You can simply SSH to your system and run the below example:

Create a Python script and edit it in your favorite text editor:
