Selenium 3.8.1, ChromeDriver 2.34 - org.openqa.selenium.WebDriverException: chrome not reachable

Question

While executing Selenium-Jvm, Chrome does not start intermittently and throws "chrome not reachable" error. Same scripts work fine for IE

Below is the code. I am using Chrome browser Version 63.0.3239.84 (Official Build) (64-bit).

package sampleSelenium;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.Dimension;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

public class RunScript {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        WebDriver driver;
        System.setProperty("webdriver.chrome.driver", "D:/browser_drivers/chromedriver.exe");
        ChromeOptions options = new ChromeOptions();
        options.addArguments("disable-infobars");

        for (int i=0; i<10;i++)
        {
            try {

                driver = new ChromeDriver(options);

                driver.manage().deleteAllCookies();
                driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
                driver.navigate().to("https://XXXX.XXXX.com/");
                Dimension dimension = new Dimension(1920, 1080);
                driver.manage().window().setSize(dimension);

                String currentWindow = driver.getWindowHandle();
                driver.switchTo().window(currentWindow);

                WebElement elm = driver.findElement(By.cssSelector("#username"));
                System.out.println(elm.isDisplayed());
                elm = driver.findElement(By.cssSelector("#password"));
                System.out.println(elm.isDisplayed());
                elm = driver.findElement(By.cssSelector("#Login"));
                System.out.println(elm.isDisplayed());

                driver.findElement(By.cssSelector("#username")).sendKeys("XXX");
                driver.findElement(By.cssSelector("#password")).sendKeys("XXX");
                driver.findElement(By.cssSelector("#Login")).click();

                WebDriverWait wait = new WebDriverWait(driver, 2);
                System.out.println("waiting");
                try {
                    WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.className("mb12")));

                }
                catch(Exception e) {
                    System.out.println(e);
                };

                driver.close();
                driver.quit();

            }
            catch(Exception e) {
                System.out.println(e);
            };


        }

    }

}

We have referred all the old posts and tried providing absolute path for chrome binary as well as chromedriver but no luck. Also tried setting no_proxy for localhost and 127.0.0.1

Answer 1

What version of ChromeDriver are you using?

Latest Release: ChromeDriver 2.34 (Released 2017/12/10)

Supports Chrome v61- 63

Previous Releases

ChromeDriver 2.33

Supports Chrome v60-62

Also, you may need more options. Here are the ones I use:

args.add("enable-automation");
args.add("test-type=browser");
args.add("disable-plugins");
args.add("disable-infobars");

I believe at minimum you also need the "enable-automation"

Answer 2

You have clubbed up 2 seperate distinct errors in a single Error Stack Trace .

As per the first set of error stack trace, the error says it all as follows :

org.openqa.selenium.TimeoutException: Expected condition failed: waiting for visibility of element located by By.className: mb12 (tried for 2 second(s) with 500 MILLISECONDS interval)

As per the errorlog the error happens in the following line :

WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.className("mb12")));

Here it is worth to mention that className as a locator should only be used if the class attribute is unique for the desired WebElement . If the class attribute of the desired element is not unique through visibilityOfElementLocated(By.className("mb12") Selenium will try for the visibility of the very first matching element in the HTML DOM which may not be your desired element or hidden . Hence instead of the locator className we should try to use either cssSelector or xpath (in absence of id , name , linkText , partialLinkText and tagName ).

Solution :

The solution for you would be to use either of the following :

• cssSelector :

   WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("tagName.class#id"))); 

• xpath :

   WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.className("//tagName[@class='class_values' and @id='id_value']"))); 

As per the second set of error stack trace, the error again says it all as follows :

org.openqa.selenium.WebDriverException: chrome not reachable
  (Driver info: chromedriver=2.34.522940 (1a76f96f66e3ca7b8e57d503b4dd3bccfba87af1),platform=Windows NT 6.1.7601 SP1 x86_64) (WARNING: The server did not provide any stacktrace information)

Driver info: driver.version: ChromeDriver

The possible reason for that is because you are trying in a loop of 10 iterations to initiate the Chrome Browser . Due to the dangling instances of previous Chrome Browser sessions new sessions can't be initiated.

Answer 3

Trouble still no resolved? I use Ch v63.0.3239.132 and Chromedriver 2.35

Simplest prototype, based on your example, work fine to me. I use absolute path for loading the driver like this:

C:\\Users\\...\\IDEA Projects\\AST\\src\\main\\resources\\Drivers\\Chrome\\chromedriver.exe
