I hear that webdriver for Chrome is being re-developed as part of the Chromium project (since the original Chrome webdriver of the selenium project is unusable). Does anyone know if development is complete? If so, where can I find the jars? Has it been pushed to maven central yet?
The new Chrome driver has been checked into the Chromium project tree, and the binaries made available on the Selenium project site. The individual language bindings for the Chrome driver will still be included in the Selenium downloads. Information about what is required to run the new Chrome driver can be found in the project wiki. Note that Chrome 12.0.712.0 or higher is required to work with the new Chrome driver.
The .jars, as of this writing, are not available yet in any Maven repository. You can expect that to change when the next public release of the compiled sources is available. In the interim, you can build from the latest sources yourself.

I am interested in getting the browser Version
I've two questions-
Question 1:- is there is a way to find out the browser version without setting up the browser?
or can we force stop the downloading of the Driver in the first place.
It is possible with the below code but the driver will be downloaded in this case.
WebDriverManager.chromedriver().setup(); //without doing this step
WebDriverManager.chromedriver().getDownloadedDriverVersion();
Question 2:-
Currently I am using wmic commands for browser detection which is used in WebDriverManager but it is failing on some systems.
what more alternatives ways are used in the WebDriverManager to fetch the browser version. I am curious to know about this as I've disabled wmic on my system still webDriverManager is working as usual(I guess with alternative methods within WebDriverManager).I am facing difficulties in understand the code. Please help me to understand the flow of the WebDriverManager like which methods/ways are used to detect the browser version and in what order.
Any help would be appreciated!
WebDriverManager
WebDriverManager is the open-source Java library that maintains the configuration management of the drivers required by Selenium WebDriver (e.g., chromedriver, geckodriver, msedgedriver, etc.) in a fully automated fashion.
Additionally, WebDriverManager provides other relevant features, such as the capability to discover browsers installed in the local system, building WebDriver objects (such as ChromeDriver, FirefoxDriver, EdgeDriver, etc.), and running browsers in Docker containers seamlessly.
The primary use of WebDriverManager is the automation of driver management (i.e., download, setup, and maintenance) of the drivers involved in your Test Automation Suite. Hence using WebDriverManager it's highly unlikely you can force stop the downloading of the Driver in the first place.
However, when you use a specific browser version for the first time in a while the matched driver version is downloaded and saved within the cache which is pretty much evident from the generated logs.
====== WebDriver manager ======
Current google-chrome version is 98.0.4758
Get LATEST chromedriver version for 98.0.4758 google-chrome
There is no [win32] chromedriver for browser in cache
Trying to download new driver from https://chromedriver.storage.googleapis.com/98.0.4758.102/chromedriver_win32.zip
Driver has been saved in cache [C:\Users\Sadanand.Kolhe\.wdm\drivers\chromedriver\win32\98.0.4758.102]
Moving forward, if the browser version and the matched driver version remains unchanged and at the same time the previous version of the downloaded version of the driver is available within the cache, the fresh downloading is avoided, which is evident from the logs generated from two back to back test execution.
====== WebDriver manager ======
Current google-chrome version is 98.0.4758
Get LATEST chromedriver version for 98.0.4758 google-chrome
Driver [C:\Users\Sadanand.Kolhe\.wdm\drivers\chromedriver\win32\98.0.4758.102\chromedriver.exe] found in cache
Regarding Q1, as of version 5, WebDriverManager allows detecting if a given browser is installed or not in the local system. To this aim, each manager provides the method getBrowserPath(). This method returns an Optional<Path>, which is empty if a given browser is not installed in the system or the browser path (within the optional object) when detected. See doc.
Regarding Q2, WebDriverManager uses internally a knowledge database called commands database. This database is a collection of shell commands used to discover the version of a given browser in the different operating systems (e.g., google-chrome --version for Chrome in Linux). This database contains WMIC commands for Windows but also queries to the registry. See doc again.
I am working with JMeter and Selenium. Installed the plugins manager and via that, installed web-driver sampler. When I look into lib folder, I found the selenium jars version are 2.52.0 which is much older. I can able to work with that without any issues. But the real problem is:
Using Maven, I updated all the selenium jars to 3.9.1 version and its dependant jars like guava, gson, commons, etc.
Now, when I open the jmx files with WebDriver sampler and driver configs, I receive below error.
Using maven, I mean, I downloaded all the jars from maven repo manually and pasted into JMeter lib folder.
Please help me to work with latest Selenium drivers in JMeter.
You won't be able to use WebDriver Sampler plugin with Selenium 3.9.1 as it explicitly relies on SessionNotFoundException class which has been removed in the latest Selenium libraries.
So the options are in:
Use WebDriver Sampler with browser version(s) supported by Selenium 2.52.0
Reach out to WebDriver Sampler plugin developers and/or maintainers at jmeter-plugins forum to check whether it is planned to update Selenium libraries and if yes - when. You can also update WebDriver Sampler source code by yourself and send pull request to the plugin maintainer.
Switch to JSR223 Sampler and Groovy language instead. Apart from being able to use latest libraries you will have full control of the WebDriver instance using DesiredCapabilities at full instead of limited subset exposed via *Driver Config elements.
I was wandering since there is many chrome drivers available on the nuGet Packages Manager, which one is fitting the best with Selenium tests, does it make any difference at all?
WebDriver ChromeDriver
WebDriverChromeDriver
Selenium.WebDriver.ChromeDriver
etc...
I'm using for my >30K lines of code (and 6 different web-sites) UI test project the
WebDriver ChromeDriver
with version 26.14.313457.1, it's a separate executable that WebDriver uses to control the Chrome browser. Again it requires Chromium/Google Chrome to be installed.
I have small doubt.
Why do we need IEdriver and Chrome Driver running selenium scrits in IE and Chrome but we do not need a firefox driver to run the script?
Is there any reason for the same?
This is because of the Native Browser approach used in WebDriver.
Each and every browser uses different JS Engine.
All drivers [Chrome Driver, IE driver, etc.,] are built based on the special JS Engine used by each browser.
Selenium offers inbuilt driver for Firefox but not for other browsers. [Not sure it may happen in future, since TestNG and JUnit library files are a part of Selenium-standalone-server right now]
Straight from a google search for FirefoxDriver, the official documentation states:
Firefox driver is included in the selenium-server-stanalone.jar available in the downloads. The driver comes in the form of an xpi (firefox extension) which is added to the firefox profile when you start a new instance of FirefoxDriver.
External drivers are the preferred process by the Selenium developers. They allow the driver versioning to be tied more closely to the browser than to Selenium, and they can be supported by the browser authors (e.g., ChromeDriver, OperaDriver). There is a long-standing plan to replace FirefoxDriver with a Mozilla-supported driver based on Mozilla's "Marionette" architecture.
Firefox driver is already included in the selenium-server-standalone.jar package.
I want to run my Geb specs with chrome driver without having to watch the tests on the browser? can this be done?
P.D.: I know I can use the HtmlUnitDriver, but this driver sometimes gives my errors (caused mainly by timeouts) that the chrome driver don't.
There is currently no way to do this with Chrome, Safari, Opera or FireFox, however there are multiple options you can do. First is to pipe the "window" into a virtual frame buffer (if you're using Linux). This process will pop open the browser, only in memory. I talk about this in my blog post (http://www.ensor.cc/2011/05/maven-javascript-unit-test-using.html) during the maven pre-integration phase
The other option is to use the brand new GhostDriver. GhostDriver is a WebDriver implementation of PhantomJS which is a headless WebKit. This is WAY better than HtmlUnit but still has some features being built out. GhostDriver is currently not in Maven Central, so you will need to manually add it to the common repository. You can then use it as a WebDriver. This has worked for me with moderate success (90% of my test cases dropped in without any changes needed).
