"uses Selenium stand alone server to run the files which is not very effective. Has it been updated to use selenium webdriver"
Using the stand-alone server is irrelevant. The stand-alone server has both Selenium RC and Selenium WebDriver built in. It all depends on which classes you are extending from.
So to your question:
Has it been updated to use selenium webdriver?
Behat is just a DSL of sorts... If you are using Behat with Selenium, then it depends on what you are extending your classes from.
Behat itself has nothing to do with selenium.
Web automation is implemented in Mink, which is used with Behat via the MinkExtension.
All the drivers supported by Mink out of the box are listen in their docs:
GoutteDriver
BrowserKitDriver
Selenium2Driver
ZombieDriver
SahiDriver
SeleniumDriver
As you probably noticed there are two selenium drivers - SeleniumDriver supports the old SeleniumRC protocol - while Selenium2Driver supports the webdriver.

from selenium docs https://www.seleniumhq.org/docs/03_webdriver.jsp#webdriver-and-the-selenium-server we don't need to run selenium-server if we are using webdriver but almost all javascript automation frameworks need selenium-server to be started before running tests. why do we need to run selenium standalone server for webdriverjs tests ?
This is not true. Given your browser/ driver pair supports directConnect. It will run without the selenium server regardless of the language binding.
For instance, Here is the directConnect reference for protractor. https://github.com/angular/protractor/blob/master/docs/server-setup.md#connecting-directly-to-browser-drivers
Here you can see how to make Selenium Standalone Server use the chromedriver. My question is, which drivers are include out the box in the Selenium Standalone Server jar?
Should I use the browsers drivers instead of the drivers included in the Selenium Standalone Server jar?
I know that with Firefox the Selenium Team recommend use the Firefox driver, but what about the others browsers?
The post you have pointed out as how to make Selenium Standalone Server use the chromedriver is a demonstration of using Selenium Standalone Server in Grid configuration i.e. through setting up Selenium Grid Hub and Selenium Grid Node.
Selenium 3.x releases doesn't supports any of the drivers out the box in the Selenium Standalone Server jar.
The main reason behind Selenium Team recommending to use the geckodriver (Firefox) and Mozilla Firefox Browser because both geckodriver and Mozilla Firefox Browser follows the W3C Specifications.
Can anyone please explain the difference between "selenium server" and "selenium server standalone" jars and use of both.
Which one to prefer?
When to use which one?
As per Selenium Documents,
You may, or may not, need the Selenium Server, depending on how you intend to use Selenium-WebDriver. If you will be only using the WebDriver API you do not need the Selenium-Server. If your browser and tests will all run on the same machine, and your tests only use the WebDriver API, then you do not need to run the Selenium-Server; WebDriver will run the browser directly.
There are some reasons though to use the Selenium-Server with Selenium-WebDriver.
You are using Selenium-Grid to distribute your tests over multiple machines or virtual machines (VMs).
You want to connect to a remote machine that has a particular browser version that is not on your current machine.
You are not using the Java bindings (i.e. Python, C#, or Ruby) and would like to use HtmlUnit Driver.
Here is a photo from the old version of selenium website:
Selenium Server is formerly known as selenium RC server.
I can not say exact selenium server standalone definition, but i can say based on the version
In the selenium server standalone server is different
I believe that "selenium server" jar IS "selenium server standalone" jar. If you look at http://www.seleniumhq.org/download/ - there is not such thing as "selenium server".
Grid and RC servers are in the same jar file. RC ("Remote Control") is deprecated in Selenium 2 and emulated in Selenium 3.
Lazily, "selenium server standalone" can be called just "selenium server", because that's what it is: proxy to selenium grid or whatever remote browsers you want to automate. "standalone" is HTTP server.
http://www.protractortest.org/#/infrastructure hints at difference in terminology: it is "standalone" when running locally, and "server" when running (standalone jar) on remote grid (which is a http server assigning jobs to multiple selenium servers, each running "standalone" jars).
If one enters via the Getting Started page at the Selenium Wiki, there is a download link to selenium-release.storage.googleapis.com. E.g. the 3.8 release directory features:
[DIR] selenium-server-3.8.1.zip 2017-12-01 19:21:38 20.58MB
[DIR] selenium-server-standalone-3.8.1.jar 2017-12-01 19:17:06 21.79MB
So there are indeed two versions. It seems a matter of packaging:
The selenium-server-3.8.1.zip contains a file selenium-3.8.1-nodeps.jar and the dependent classes as .jar files ("jars in zip"):
..
---x------ 63504 1-Feb-1985 00:00:00 libs/jcommander-1.48.jar
..
---x------ 857721 1-Feb-1985 00:00:00 selenium-3.8.1-nodeps-sources.jar
---x------ 2137810 1-Feb-1985 00:00:00 selenium-3.8.1-nodeps.jar
while the selenium-server-standalone-3.8.1.jar contains the dependent classes and its own classes as direct entries ("class files in jar"):

Selenium is an opensource, web application automation testing tool suite which provides cross platform and cross browser automation facility.
Selenium is composed of multiple software tools that includes:-
(1). Selenium IDE, (2). Selenium RC, (3). Selenium WebDriver, (4). Selenium Grid
Coming to the Selenium Server,
The Selenium Server is a Selenium RC(Remote Control) component that which launches and kills browsers, interprets and runs the Selenese commands passed from the test program, and acts as an HTTP proxy, intercepting and verifying HTTP messages passed between the browser and the AUT(Application Under Test).
So, Selenium Server is needed to run Selenium RC and Selenium WebDriver tests remotely over multiple machines or VMs using Selenium Grid.
And the Selenium Server Standalone is a bundled jar that contains WebDriver API, Selenium Server and the Selenium Grid for running the tests locally and remotely across many platforms and browsers.
The Selenium Server is needed in order to run Remote Selenium
WebDriver. Selenium 3.X is no longer capable of running Selenium RC
directly, rather it does it through emulation and the
WebDriverBackedSelenium interface.
see https://docs.seleniumhq.org/download/
So,if you use Selenium RC,the Seleniium Server is what you need.if you use Selenium 3.X and update,selenium-server-standalone is what you need.I have the same question and i find the answer.
I have been given the following job from my boss:
three years ago a former employee created selenium tests for our project and committed them via eclipse
now I have to update the tests due to the fact that the software has changed through time.
I created new IDE tests, instead of editing the old ones.
I have committed them through CVS in the project folder and I access them via a browser (selenium has some folder in the project)
when I run these tests via IDE, they run fine, but when I run them via the TEstRUnner that is in the old selenium installation, there are a lot of errors.
Should I install new version of Selenium in the project folder and what should it be?
Or should I just run the tests from IDE instead? (I read somewhere that TestRunner will be deprecated)
How are tests made in IDE run through Web Driver?
Have you looked at Selenium Builder? It supports migrating existing scripts, works well with Sauce Labs and there is also a Jenkins plugin](https://wiki.jenkins-ci.org/display/JENKINS/Selenium+Builder+Plugin) available.
Tests built using Selenium IDE are built using Selenium RC (1.0), and selenium WebDriver is the foundation of Selenium 2.0. Selenium has a migration document for this transition. In moving to Web Driver, you might be required to code the tests yourself, rather than using the point and click Selenium IDE.
Additionally, there is a hybrid approach for using Selenium RC code on Selenium Web Driver: http://docs.seleniumhq.org/docs/03_webdriver.jsp#alternative-back-ends-mixing-webdriver-and-rc-technologies
In order to run the Web Driver tests, you will need to have a selenium server or local browser to execute these tests. Some examples are SauceLabs, Selenium Grid, a standalone Selenium Server, or I believe you allow Web Driver to directly control the browser on the computer executing the code.
I'd like to setup a Selenium server so that clients can record tests locally, recorded tests can be replayed and tested on an Ubuntu server with Firefox + Chrome.
Unfortunately the Selenium site is so confusing and mentions so many different projects (Selenium 1, Selenium 2, Selenium RC, Selenium Grid) that I'm not sure where to start.
How do I go about setting up Selenium Server on an Ubuntu box?

Selenium has multiple versions
IDE - mainly to record the test and play it back. It is mainly a Firefox Addon. This can be used for very basic testing. You can also export the recorded test to selenium RC. All these mentioned in seleniumhq.org->documentation section: http://docs.seleniumhq.org/docs/
RC - Like any other automation tool, you can write your own code to run the test rather than just recording and playing it back. This has far better capabilities than IDE including support for several languages (Java, Javascript, Ruby, PHP, Python, Perl and C#) and support for almost every browser out there in various platform.
Grid - This helps in running multiple tests in parallel.
To record and run the test in Firefox (NOT CHROME) its very easy. This doesn't require a selenium server running.
record the whole test
save it in a file
Copy the file to Ubuntu machine
Open the same test using IDE in Ubuntu machine and run it again in firefox
If you want to run on chrome, then you need to go to the next level of using selenium RC. And this requires the selenium server running.
How do I go about setting up Selenium
Server on an Ubuntu box
Download selenium-server jar from here. Copy this to any directory in your ubuntu server
Open a terminal and navigate to the folder which has the selenium server jar.
Enter java -jar selenium-server-jarfilename.jar
Selenium server will start on port 4444 by default and keep listening to the tests.
The site is confusing in terms of the versioning and names. Selenium is the name of the entire project which started off as Selenium RC (remote control). Selenium RC is the old version of the API which is also sometimes called Selenium 1. Selenium 2 is the newest version and the latest release was last week being Selenium RC2 (release candidate). This uses a different API to Selenium RC. The new API is known as WebDriver. The new API still allows you to access the older Selenium RC but only for backwards compatibility.
Since you're starting now, there is no reason for you to use the Selenium RC API. You should instead use the advanced user interactions which are part of WebDriver. Setting up WebDriver is pretty easy and there is a decent guide on it here. You should note that the API used there is the older standard (2.0 beta) which uses WebElements. The new API (advanced user interactions) decouples actions from the elements they are performed on a lot more. I would recommend you use the latest versions of the API which is being actively supported rather than older deprecated versions.
Since you want to do this all locally, the second link I gave you should be enough to get you up and running. Assuming you're going to be using the Java bindings it is as simple as:
public class Selenium2Example {
public static void main(String[] args) {
// Create a new instance of the Firefox driver
// Notice that the remainder of the code relies on the interface,
// not the implementation.
WebDriver driver = new FirefoxDriver();
// And now use this to visit Google
driver.get("http://www.google.com");
Actions builder = new Actions( driver );
builder.sendKeys( driver.findElement( By.name("q") ), "Cheese!" );
Action action = builder.build();
action.perform();
//Close the browser
driver.quit();
}
}
This is the example code edited to use advanced user interactions.
You must have two things to write and execute selenium tests.
1) Selenium Server is also known as Selenium RC (Remote Control). You can go to this link and download Selenium Server.
You can start selenium server with command java -jar ur_selenium_server.jar
2) Client Driver: Using client-driver you can code selenium tests. It consists of combination of selenium commands that perform certain actions on the UI. For e.g. click, select etc.
Selenium supports many different language bindings for client-driver. Download appropriate client-driver for your preferred language from above download page.
You can refer client driver apis and code your tests.
Hope this helps
