Note: the xml created for this code runs successfully on terminal.i think issue is with chromedriver

SELENIUM CODE:

   public class cmddd {
      @Test
      public void f() throws InterruptedException {
          System.setProperty("webdriver.chrome.driver", "/home/dev2/Downloads/newchromedriver/chromedriver");
            WebDriver m = new ChromeDriver();
            m.get("https://www.google.com/");
            System.out.println("passed");

回答1:

Check your chromedriver version and chromebrowser version. I had noticed this behaviour when there is a version mismatch.

You can refer this link http://chromedriver.chromium.org/downloads

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• You are using chromedriver=2.40
• Release Notes of chromedriver=2.40 clearly mentions the following :

Supports Chrome v66-68

• Possibly you are using the latest Chrome Browser i.e. chrome=72.0
• As per ChromeDriver - WebDriver for Chrome:
  • If you are using Chrome version 73, please download ChromeDriver 73.0.3683.20
  • If you are using Chrome version 72, please download ChromeDriver 2.46 or ChromeDriver 72.0.3626.69
  • If you are using Chrome version 71, please download ChromeDriver 2.46 or ChromeDriver 71.0.3578.137
  • For older version of Chrome, please see this discussion for the version of ChromeDriver that supports it.

Solution

• Upgrade Chrome version to Chrome v72 level.
• As per ChromeDriver - WebDriver for Chrome upgrade ChromeDriver to ChromeDriver v2.46 or ChromeDriver 72.0.3626.69.
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• Take a System Reboot.
• Execute your @Test.
• Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
