I am trying to launch Mozilla but still I am getting this error:
Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver. The latest version can be downloaded from https://github.com/mozilla/geckodriver/releases
I am using Selenium 3.0.01
Beta version and Mozilla 45
. I have tried with Mozilla 47
too. but still the same thing.
GeckoDriver serves as a proxy between WebDriver enabled clients and the Firefox browser. In other words, GeckoDriver is a link between Selenium tests and the Firefox browser. It is a proxy for using W3C WebDriver-compatible clients that lets them interact with Gecko-based browsers.
The Selenium
client bindings will try to locate the geckodriver
executable from the system PATH
. You will need to add the directory containing the executable to the system path.
On Unix systems you can do the following to append it to your system’s search path, if you’re using a bash-compatible shell:
export PATH=$PATH:/path/to/geckodriver
On Windows you need to update the Path system variable to add the full directory path to the executable. The principle is the same as on Unix.
All below configuration for launching latest firefox using any programming language binding is applicable for Selenium2
to enable Marionette explicitly. With Selenium 3.0 and later, you shouldn't need to do anything to use Marionette, as it's enabled by default.
To use Marionette in your tests you will need to update your desired capabilities to use it.
Java :
As exception is clearly saying you need to download latest geckodriver.exe
from here and set downloaded geckodriver.exe
path where it's exists in your computer as system property with with variable webdriver.gecko.driver
before initiating marionette driver and launching firefox as below :-
//if you didn't update the Path system variable to add the full directory path to the executable as above mentioned then doing this directly through code System.setProperty("webdriver.gecko.driver", "path/to/geckodriver.exe"); //Now you can Initialize marionette driver to launch firefox DesiredCapabilities capabilities = DesiredCapabilities.firefox(); capabilities.setCapability("marionette", true); WebDriver driver = new MarionetteDriver(capabilities);
And for Selenium3
use as :-
WebDriver driver = new FirefoxDriver();
If you're still in trouble follow this link as well which would help you to solving your problem
.NET :
var driver = new FirefoxDriver(new FirefoxOptions());
Python :
from selenium import webdriver from selenium.webdriver.common.desired_capabilities import DesiredCapabilities caps = DesiredCapabilities.FIREFOX # Tell the Python bindings to use Marionette. # This will not be necessary in the future, # when Selenium will auto-detect what remote end # it is talking to. caps["marionette"] = True # Path to Firefox DevEdition or Nightly. # Firefox 47 (stable) is currently not supported, # and may give you a suboptimal experience. # # On Mac OS you must point to the binary executable # inside the application package, such as # /Applications/FirefoxNightly.app/Contents/MacOS/firefox-bin caps["binary"] = "/usr/bin/firefox" driver = webdriver.Firefox(capabilities=caps)
Ruby :
# Selenium 3 uses Marionette by default when firefox is specified # Set Marionette in Selenium 2 by directly passing marionette: true # You might need to specify an alternate path for the desired version of Firefox Selenium::WebDriver::Firefox::Binary.path = "/path/to/firefox" driver = Selenium::WebDriver.for :firefox, marionette: true
JavaScript (Node.js) :
const webdriver = require('selenium-webdriver'); const Capabilities = require('selenium-webdriver/lib/capabilities').Capabilities; var capabilities = Capabilities.firefox(); // Tell the Node.js bindings to use Marionette. // This will not be necessary in the future, // when Selenium will auto-detect what remote end // it is talking to. capabilities.set('marionette', true); var driver = new webdriver.Builder().withCapabilities(capabilities).build();
Using RemoteWebDriver
If you want to use RemoteWebDriver
in any language, this will allow you to use Marionette
in Selenium
Grid.
Python:
caps = DesiredCapabilities.FIREFOX # Tell the Python bindings to use Marionette. # This will not be necessary in the future, # when Selenium will auto-detect what remote end # it is talking to. caps["marionette"] = True driver = webdriver.Firefox(capabilities=caps)
Ruby :
# Selenium 3 uses Marionette by default when firefox is specified # Set Marionette in Selenium 2 by using the Capabilities class # You might need to specify an alternate path for the desired version of Firefox caps = Selenium::WebDriver::Remote::Capabilities.firefox marionette: true, firefox_binary: "/path/to/firefox" driver = Selenium::WebDriver.for :remote, desired_capabilities: caps
Java :
DesiredCapabilities capabilities = DesiredCapabilities.firefox(); // Tell the Java bindings to use Marionette. // This will not be necessary in the future, // when Selenium will auto-detect what remote end // it is talking to. capabilities.setCapability("marionette", true); WebDriver driver = new RemoteWebDriver(capabilities);
.NET
DesiredCapabilities capabilities = DesiredCapabilities.Firefox(); // Tell the .NET bindings to use Marionette. // This will not be necessary in the future, // when Selenium will auto-detect what remote end // it is talking to. capabilities.SetCapability("marionette", true); var driver = new RemoteWebDriver(capabilities);
Note : Just like the other drivers available to Selenium from other browser vendors, Mozilla has released now an executable that will run alongside the browser. Follow this for more details.
You can download latest geckodriver executable to support latest firefox from here
.
System.setProperty("webdriver.gecko.driver","C:\\geckodriver-v0.10.0-win64\\geckodriver.exe"); WebDriver driver = new FirefoxDriver();
