ChromeDriver initialized by Selenium remains active in the background

Question

ChromeDriver initialized by Selenium remains active in the background

Having trouble completely deleting a project due to the chromedriver instance running in the background despite no code execution. Please refer to the image linked below: https://i.stack.imgur.com/bt1Tb.png

Error encountered during project deletion:https://i.stack.imgur.com/pKIO0.png

Consider the following code snippet:

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class Test {

    public static void main(String[] args) throws Exception {

        String url = "https://www.google.com";
        System.setProperty("webdriver.chrome.driver", "src/driver/chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.manage().window().maximize();
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        driver.get(url);
        System.out.println(driver.getTitle());

    }
}

Running this code multiple times results in several background instances persisting. Even restarting Eclipse doesn't resolve the issue.

The problem stems from missing the line:

driver.close();

Typically, once the main-thread terminates, all associated instances should end as well. Is this a known bug or an error in my scripting?

Thanks for any help in advance.

Answer 1

Answer №1

It is crucial to address a few key points:

To resolve the issue, attempt running this code five times to observe five background instances running: This occurs because each time a new driver instance is opened without being released.
Restarting Eclipse has been unsuccessful in resolving the problem: It's important to note that Eclipse serves as an IDE (Integrated Development Environment) for constructing programming steps. This includes writing instructions for Selenium to manage browser sessions and driver sessions. However, Eclipse does not dictate the execution of Selenium actions, such as opening or closing browser sessions. Therefore, restarting Eclipse will not have any impact.
driver.close(): This command specifically closes the active browser session/window associated with the current driver focus.
When the main-thread terminates, all accompanying instances should also cease operation: The WebDriver instance (referred to as 'driver' in your code) initiates every browser session. Hence, upon program completion, it is essential to call driver.quit() to close all browser windows, quit the driver, and safely end the session.

However, you can forcibly terminate all WebDriver variants like geckodriver, selenium-chromedriver, selenium-iedriver using OS-specific methods as outlined below:

Java Solution(Windows):

import java.io.IOException;

public class Kill_ChromeDriver_GeckoDriver_IEDriverserver 
{
    public static void main(String[] args) throws Exception 
    {
        Runtime.getRuntime().exec("taskkill /F /IM geckodriver.exe /T");
        Runtime.getRuntime().exec("taskkill /F /IM chromedriver.exe /T");
        Runtime.getRuntime().exec("taskkill /F /IM IEDriverServer.exe /T");
    }
}

Python Solution(Windows):

import os
os.system("taskkill /f /im geckodriver.exe /T")
os.system("taskkill /f /im chromedriver.exe /T")
os.system("taskkill /f /im IEDriverServer.exe /T")

Python Solution(Cross Platform):

import os
import psutil

PROCNAME = "geckodriver" # or chromedriver or IEDriverServer
for proc in psutil.process_iter():
    # check whether the process name matches
    if proc.name() == PROCNAME:
        proc.kill()

Since chromedriver is an executable file, it runs as a separate thread and may not close automatically if the driver.close() method is not called. In such cases, manually closing the chromedriver process is necessary. You can either do this through Task Manager or use the following command in Command Prompt:

 taskkill /f /im chromedriver.exe

This command allows you to terminate any lingering processes on your Windows device.

Although it may veer off topic, I found a solution to the issue of

chromedriver lingering in the background

. Instead of using driver.close, which doesn't completely close the session, I came across this insightful response:

The key is to use driver.quit whenever you want to terminate the program. By doing so, all browser windows will be closed and the WebDriver session will properly end. Failing to use driver.quit can lead to memory leakage errors as files remain uncleared from memory.

It is important to remember to always close the Chrome driver after executing it in order to properly shut down the program. Utilizing a suitable testing framework such as JUnit for Java will help streamline the process and prevent any confusion during test execution.

To create a batch file named killchorme.bat, follow the command below:

taskkill /f /im chromedriver.exe

After creating the bat file, make sure to run it before starting your chrome driver by using this code: Runtime.getruntime().exec("killchrome.bat")
