in python it can be done with following code

from robot.libraries.BuiltIn import BuiltIn


def _browser(self):
    return BuiltIn().get_library_instance('Selenium2Library')._current_browser()

Finally, here's the solution to this problem.

I added this line to my build.sbt file :

For SBT 0.x:

unmanagedResourceDirectories in Test <+=  baseDirectory ( _ /"target/web/public/test" )

For SBT 1.x:

unmanagedResourceDirectories in Test +=  baseDirectory ( _ /"target/web/public/test" ).value

Thanks to @MarkVedder and @JarmoPertman for their great comments who put me on this solution!

You are using drive.quit() instead of driver.close(). quit closes the driver and window. This is why you get the child error because the driver is no longer available. close(), will close the window but keep the driver alive. I would only use quit at the very end of your program (like a cleanup routine). I ran your code (modified below) on my machine and did not have any errors. Also, you should put this around a try/catch so that you can see what is going on. I found with selenium that the try/catch sometimes shows errors that your console does not show. I had something similar with an earlier project and the try catch assisted with debugging.

package com.kurt.stackoverflow.selenium;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class Gecko_Driver
{
    public static void main(String[] args) throws InterruptedException{

    try
    {
       System.setProperty("webdriver.gecko.driver","C:\\tmp\\geckodriver-v0.11.1-win64\\geckodriver.exe");
       WebDriver driver = new FirefoxDriver();
       driver.get("http://www.toolsqa.com");
       Thread.sleep(5000);
       driver.close();
    }
    catch (Exception e)
    {
       System.out.println("Caught message " + e.getMessage());
       driver.close();
    }
}

}

You can only wait on an object if you've acquired the lock for it using synchronized.

I don't know whether you're meant to use wait using WebDriver - if you are, you'd need something like:

synchronized (driver)
{
    driver.wait();
}

However, if you're waiting for something to occur, it's more likely that there's an alternative method you're meant to be using. Perhaps WebDriverWait?

@Vel Ganesh - I dont know if this can be verified using selenium. But can be definitely done using Sikuli. You can check sikuli.org for details. Sikuli has a Java API and so can be integrated with WebDriver code as well.

If quit() has been called, driver.toString() returns null:

>>> FirefoxDriver: firefox on XP (null))

Otherwise, it returns a hashcode of the object:

>>> FirefoxDriver: firefox on XP (9f897f52-3a13-40d4-800b-7dec26a0c84d)

so you could check for null when assigning a boolean:

boolean hasQuit = driver.toString().contains("(null)");

A Regular refresh may reload the page from its cache.

A Hard refresh reloads from the server, not from cache.

If you wish to delete the Cache too use Cache.delete():

see MDN Web Docs on Cache.delete().

The answer:

You can use location.reload(true); with execute_script:

driver.execute_script("location.reload(true);")

Reloads the resource from the current URL. Its optional unique parameter is a Boolean, which, when it is true, causes the page to always be reloaded from the server. If it is false or not specified, the browser may reload the page from its cache.

For more info see MDN Web Docs on Location.

Hope this helps!

I got this solution which is working well for all three browser(Firefox, Chrome and IE).

from selenium import webdriver
import time
import win32com.client

driver=webdriver.Firefox()
driver.maximize_window()
driver.get('https://www.engprod-charter.net/')
shell = win32com.client.Dispatch("WScript.Shell")   
shell.Sendkeys("username")  
time.sleep(2)
shell.Sendkeys("{TAB}")
time.sleep(2)
shell.Sendkeys("password") 
time.sleep(2)
shell.Sendkeys("{ENTER}")
time.sleep(2)
driver.quit()

Note : Install win32com.client if you have not downloaded. To install win32com.client use below command

pip install pypiwin32

You can use assertTrue(boolean condition, String message) for this and give the details in the message

boolean isEqual = actualPopUp.equals(expectedPopUpV1) || actualPopUp.equals(expectedPopUpV2);
Assert.assertTrue(isEqual, "The text " + actualPopUp + " is not " + expectedPopUpV1 + " or " + expectedPopUpV2);
