How to enable Firefox device simulation with WebDriver? - selenium

I would like to run some Selenium tests in Firefox, using the device simulation feature to test for mobile devices.
For Chrome, this is exposed through ChromeDriver, but FirefoxOptions doesn't seem to have any such option, and my search for any related profile preference or command-line option didn't turn up anything.
Is there a way to do this in Firefox? I'd prefer it to Chrome because the built-in device list of Chrome seems to be very outdated.

playwright integration with Selenium Grid

I have started using playwright automation tool from last few weeks, I want to understand, Is it possible to run playwright test using selenium grid? how I can point my test cases to grid hub endpoint using playwright?
In case of selenium we simply use RemoteWebdriver but I am not finding similar option in playwright.
Yes it is. You can use BrowserType.connect_over_cdp() to connect to your existing Chromium browsers over the Chrome DevTools Protocol. But this has the downside that you can't use WebKit or Firefox with it.

MicrosoftWebDriver 16299, 15063 doesn't work when I minimise Edge browser window

When I execute tests using MicrosoftWebDriver for Edge all works fine, but when I minimise the window all tests become failed. Does Edge or MicrosoftWebDriver have any options to avoid that behavior?
As you have been trying to minimise the Browser Window while your Test Execution is In Progress it will be against all the Best Practices. At this point it is worth to mention that as Selenium mocks the User Actions hence Selenium needs Browser focus. If the focus is lost Selenium won't be able to execute the lines of code. Consider the following steps while your Test Execution :
Browser Maximize : While you execute your tests always keep the Web Browser maximized so majority of the elements are within the Viewport
As per best practices, you should try to execute your Test Scripts / Automation Framework in an isolated Test Environment away from Manual Intervention with all the required Software and Hardware configurations and setup.
You can find a detailed discussion in How to run chrome driver in background using selenium with Ruby for Mac OSx?
You also have an option to use Google Chrome or Mozilla Firefox in Headless version.
For Firefox you can find a detailed discussion in How to make firefox headless programatically in Selenium with python?
For Chrome you can find a detailed discussion in selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH error with Headless Chrome
For Ghost Browser you can find a detailed discussion in Which drivers support “no-browser”/“headless” testing?

Why do we need IEDriver and ChromeDriver but no Firefox Driver?

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.

Robot Framework browser support

Has the robot framework support for IExplorer or only for Firefox and Chrome?
(If yes, how to configure it?)
Thanks!
Robot Framework does not, in itself, support any particular browser, so I am guessing you are referring to either SeleniumLibrary or Selenium2Library which use selenium and selenium 2 respectively. The browser support of these is well documented at seleniumhq and there is much support out there. It is recommended for new projects to use Selenium2Library as this will receive ongoing support.
Please check the driver compatiblity for browser.
You might have already known of IE driver.
Apart from that you also need to check Python version- Selenium2 version - IE Driver version - IE browser version compatibility.
In addition to #theheadofabroom 's answer, I should add that Internet Explorer does not play well with Robot Framework. Your test might not work for any number of reasons on IE while it may work just fine on FireFox and Chrome, but the most common is timing. IE is just slow enough that when Robot Framework goes to click on the next element, it searches the page for it, but it hasn't loaded in yet. As long as you have the Selenium webdriver for IE installed correctly and have written your Robot Framework code correctly, I'd recommend adding some Sleep keywords between actions to slow your code down and increase the probability that the element you want to click will load before Robot Framework searches the page for it. This is especially true if you're writing for Chrome and want to send it to either Firefox or IE.
Open Browser ${WEBAPPURL} ${BROWSER} is the keyword to open the browser.
For Firefox you can use firefox/ff instead of ${BROWSER}
For Google Chrome you can use googlechrome/gc/chrome instead of ${BROWSER}
For Internet Explorer you can use internetexplorer/ie instead of
${BROWSER}
For Firefox you don't need any driver but IE and Chrome you need to install the drivers
You can find the installers in and info here for Chrome and here for IE
Download IEdriver exe from here and put this exe file in Scripts folder of your Python installation directory. For eg, in my case it is C:\Python27\Scripts.
Ride will now launch IE for you.
Robot class supports keyboard inputs regardless of the browser. It is a class from the java.awt package and not specific to any browser. It is used in automation for performing operations on the web browser(stand alone application) in which a web-page is being automated
Note that it cannot perform operations directly on the web browser as it's a stand alone application, but can make use of keyboard shortcuts to indirectly perform the operation.
For example, if you want to open a new tab in a browser, you can use the Robot class to press Ctrl+t instead of trying to click on the new tab.
Code to use it to open a new tab in your program
Webdriver driver = new ChromeDriver(); //FirefoxDriver(), IntrrnetExplorerDriver();
driver.get("......");
//code goes here
//to open a new tab
Robot rob = new Robot();
rob.keyPress(Keys.VK_CTRL);
rob.keyPress(Keys.VK_t);
rob.keyRelease(Keys.VK_CTRL);
rob.keyRelease(Keys.VK_t);
//itetator to switch between the tabs

Run Geb tests with chromeDriver without opening the browser

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).
