The address wasn’t understood Firefox doesn’t know how to open this address

Question

PROBLEM: FF Browser is showing this error on running following program : The address wasn’t understood.Firefox doesn’t know how to open this address because one of the following protocols (c) isn’t associated with any program or is not allowed in this context.You might need to install other software to open this address.How to resolve this error?

PROGRAM:

package com.packt.webdriver.chapter3;

import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.*;

public class ActionBuildPerform
{
   public static void main(String[] args)
    {
    System.setProperty("webdriver.gecko.driver","C:\\Users\\Pragati    Chaturvedi\\Desktop\\Selenium Web Driver\\geckodriver.exe");
    WebDriver driver = new FirefoxDriver();
    driver.get("C:\\Users\\Pragati Chaturvedi\\Desktop\\Selenium Web Driver\\8850OS_Code\\Chapter 2\\HTML\\Selectable.html");
    WebElement one = driver.findElement(By.name("one"));
    WebElement three = driver.findElement(By.name("three"));
    WebElement five = driver.findElement(By.name("five")); // Add all the actions into the Actions builder.
    Actions builder = new Actions(driver);
    builder.keyDown(Keys.CONTROL).click(one).click(three).click(five).keyUp(Keys.CONTROL); // Generate the composite action.
    Action compositeAction = builder.build(); //Perform the composite action.
    compositeAction.perform();
}

}

Answer 1

Browsers cannot open files directly, you always need to specify a protocol, eg http:// or file://.

driver.get("C:\\Users\\Pragati Chaturvedi\\Desktop\\Selenium Web Driver\\8850OS_Code\\Chapter 2\\HTML\\Selectable.html");

This should be replaced by something like:

driver.get("file:///C:\\Users\\Pragati Chaturvedi\\Desktop\\Selenium Web Driver\\8850OS_Code\\Chapter 2\\HTML\\Selectable.html");

Read more about the file URI scheme here: https://en.wikipedia.org/wiki/File_URI_scheme

Examples:

file://localhost/c:/WINDOWS/clock.avi

file:///c:/WINDOWS/clock.avi

Make sure you try to open the file manually first in Firefox to see it works. You can also open the file with Firefox and then copy the URI.

Answer 2

Are you missing a } here:

  compositeAction.perform();
  } <-------
}

?

It is missing in your code but maybe it is partial code.
