Как установить chromedriver на windows 10

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.

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:

Скачать ChromeDriver для Linux, Windows и Mac

Заходим на сайт: https://sites.google.com/a/chromium.org/chromedriver/downloads

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.

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).

Setup

ChromeDriver is a separate executable that Selenium WebDriver uses to control Chrome. It is maintained by the Chromium team with help from WebDriver contributors. If you are unfamiliar with Selenium WebDriver, you should check out the Selenium site.

Follow these steps to setup your tests for running with ChromeDriver:

• Ensure Chromium and Google Chrome are installed in a recognized location.
  • ChromeDriver expects you to have Chrome installed in the default location
    for your platform. You can
    force ChromeDriver to use a custom location
    by setting a special capability.
• Download the ChromeDriver binary for your platform.
• Help WebDriver find the downloaded ChromeDriver executable.

Any of these steps should work:

1. Include the ChromeDriver location in your PATH environment variable
2. (Java only) Specify its location using the webdriver.chrome.driver system property (see sample below)
3. (Python only) Include the path to ChromeDriver when instantiating webdriver.Chrome. See the following samples.

Sample Java test

import org.openqa.selenium.*;
import org.openqa.selenium.chrome.*;
import org.junit.Test;
public class GettingStarted {   
@Test   
public void testGoogleSearch() throws InterruptedException {
  // Optional. If not specified, WebDriver searches the PATH for chromedriver.
  // System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
  // WebDriver driver = new ChromeDriver();
  driver.get("http://www.google.com/"); 
  Thread.sleep(5000);  // Let the user actually see something!
  WebElement searchBox = driver.findElement(By.name("q"));
  searchBox.sendKeys("ChromeDriver");
  searchBox.submit(); 
  Thread.sleep(5000);  // Let the user actually see something!
  driver.quit();  
 }
}

Sample Python test

import time
from selenium import webdriver

driver = webdriver.Chrome('/path/to/chromedriver')  # Optional argument, if not specified will search path.
driver.get('http://www.google.com/')
time.sleep(5) # Let the user actually see something!
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!
driver.quit()

Control ChromeDriver’s lifetime

The ChromeDriver class starts the ChromeDriver server process at creation and
terminates it when quit is called. This can waste a significant amount of time
for large test suites where a ChromeDriver instance is created per test. There
are two options to remedy this, ChromeDriverService and starting ChromeDriver
separately.

ChromeDriverService

Use the ChromeDriverService. This is available for most languages and lets you start or stop the ChromeDriver server yourself. Here’s a Java example, with JUnit 4:

import java.io.*;
import org.junit.*;
import org.openqa.selenium.*;
import org.openqa.selenium.chrome.*;
import org.openqa.selenium.remote.*;
public class GettingStartedWithService {
  private static ChromeDriverService service;
  private WebDriver driver;
  @BeforeClass
  public static void createAndStartService() throws IOException {
      service = new ChromeDriverService.Builder()
              .usingDriverExecutable(new File("/path/to/chromedriver"))
              .usingAnyFreePort()
              .build();
      service.start();
  }
  
  @AfterClass   
  public static void stopService() {
    service.stop();
  }

  @Before   
  public void createDriver() {
    driver = new RemoteWebDriver(service.getUrl(), new ChromeOptions());
  }

  @After   public void quitDriver() {
    driver.quit();
  }

  @Test   
  public void testGoogleSearch() {
    driver.get("http://www.google.com");
    // rest of the test...
  }
}

Python:

import time
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
service = Service('/path/to/chromedriver')
service.start()
driver = webdriver.Remote(service.service_url)
driver.get('http://www.google.com/');
time.sleep(5) # Let the user actually see something!
driver.quit()

Start ChromeDriver separately

Start the ChromeDriver server separately before running your tests, and connect
to it using the Remote WebDriver.

Terminal:

$ ./chromedriver
Starting ChromeDriver
76.0.3809.68 (...) on port 9515
...

Java:

import java.net.*;
import org.openqa.selenium.*;
import org.openqa.selenium.chrome.*;
import org.openqa.selenium.remote.*;  

public class GettingStartedRemote {

  public static void main(String[] args) throws MalformedURLException {
    WebDriver driver = new RemoteWebDriver(
        new URL("http://127.0.0.1:9515"),
        new ChromeOptions());
    driver.get("http://www.google.com");
    driver.quit();
  }
}

ChromeDriver is a standalone executable server that acts as an intermediary between your WebDriver-based test scripts and the Google Chrome web browser. It facilitates the communication between your code and the browser, allowing you to automate interactions with web pages using programming languages like Python, Java, Ruby, or C#.

Here’s what ChromeDriver does:

1. Browser Control: ChromeDriver allows you to open, control, and manage instances of the Google Chrome web browser programmatically. You can open and close browser windows, navigate to specific URLs, interact with web elements, and perform various actions just as a human user would.
2. Automation: It provides a way to automate tasks on web pages, such as filling out forms, clicking buttons, submitting data, and extracting information from websites. This is particularly useful for web scraping, web testing, and web application automation.
3. Cross-Platform: ChromeDriver is available for multiple operating systems, including Windows, macOS, and Linux. This cross-platform compatibility makes it a versatile tool for web automation across different environments.
4. Selenium Integration: ChromeDriver is commonly used in conjunction with the Selenium WebDriver framework. Selenium WebDriver is a popular tool for automating web browsers, and ChromeDriver serves as the WebDriver implementation for Google Chrome.

When you write code using a WebDriver library (e.g., Selenium WebDriver), you can specify that you want to use ChromeDriver as the driver for Google Chrome. Your code then sends commands to ChromeDriver, which translates those commands into actions performed by the Chrome browser. This allows you to automate tasks, conduct web testing, and gather data from websites in an automated and reproducible manner.

ChromeDriver Installation on PC

Check Your Chrome Browser Version

First, you need to determine the version of Google Chrome installed on your computer. You can find this information by opening Chrome, clicking on the three-dot menu (top-right corner) > Help > About Google Chrome. Note down the version number.

Download ChromeDriver

Go to the ChromeDriver download page: https://sites.google.com/chromium.org/driver/. On this page, you will find ChromeDriver downloads for different versions of Chrome.

• Find the Chrome version that matches the one installed on your computer.
• Click on the link to download ChromeDriver for that version. Make sure to choose the appropriate version for your operating system (e.g., Windows, macOS, or Linux).

• For Windows: After downloading, extract the ChromeDriver executable (chromedriver.exe) from the ZIP file to a directory of your choice.
• For macOS or Linux: After downloading, extract the ChromeDriver executable (chrome driver) from the ZIP file to a directory of your choice. You may need to make it executable using the chmod +x chromedriver command in the terminal.

Add ChromeDriver to System PATH

• On Windows: You need to add the directory containing chromedriver.exe to your system’s PATH environment variable. You can do this by editing your system’s Environment Variables and adding the directory to the PATH variable.
• On macOS and Linux: You can place the chrome driver executable in a directory that is already in your PATH, or you can add its directory to your PATH in your shell’s profile file (e.g., .bashrc, .zshrc, or .profile).

For example:

export PATH=$PATH:/path/to/chromedriver_directory

I am using a Windows machine, so for me it was D:\lab\server\chromedriver-win64. You can launch System Properties by typing SystemPropertiesAdvanced on the RUN prompt.

Verify Installation

Open a terminal or command prompt and type chromedriver --version. You should see the version of ChromeDriver displayed, which confirms the installation.

You can now use ChromeDriver with automation tools or scripts like Selenium to interact with Google Chrome programmatically. Make sure to include the appropriate driver path in your automation code.

To launch a website use the following python code.

from selenium import webdriver
from selenium.webdriver.common.by import By
import time

driver = webdriver.Chrome()
driver.get('https://tech-champion.com/tech-fundamentals/blockchain-basics-what-is-blockchain-technology/')
time.sleep(5)
driver.quit()
