I want to open Chrome on the client side using selenium webdriver. I have a piece of code and it works fine for single system, but I can't access it in another system.
I am using selenium-server-standalone-2.44.0.jar, chromedriver for the purpose.
This is the code I use to open browser:
System.setProperty("webdriver.chrome.driver", file.getAbsolutePath());
driver=new ChromeDriver();
Is the ChromeDriver on the other system in the same place as on the single system?
Try something like the following (in java):
String currentDir = System.getProperty("user.dir");
String chromeDriverLocation = currentDir + "/../tools/chromedriver/chromedriver.exe";
System.setProperty("webdriver.chrome.driver", chromeDriverLocation);
ChromeOptions options = new ChromeOptions();
options.addArguments("test-type");
options.addArguments("disable-plugins");
options.addArguments("disable-extensions");
WebDriver chrome = new ChromeDriver(options);
chrome.get("http://www.google.com");
Selenium webdriver can be used in different languages.
I can give you an example.
A web application is developed by using python in back-end and front-end is built up with html and a interpreted programming language like javascript. If we use selenium webdriver with python then browser opens at server side. and if we use selenium with javascript then browser opens at client side.

Very new to Selenium testing and after reading the doc I tried to setup my own Selenium Grid Hub but I'm failing to use it for my local testing.
I setup the Selenium Grid Hub on a kubernetes cluster (following https://github.com/kubernetes/examples/tree/master/staging/selenium) and I manage to reach my nodes.
I've built a simple java application to test this is working as expected and I manage to reach web based url like http://www.google.com but I would like to be able to test my local app by using my RemoteWebDriver.
Here is what is actually working:
log.info("test selenium");
ChromeOptions chromeOptions = new ChromeOptions();
WebDriver driver = new RemoteWebDriver(new URL("http://my-k8-node.com:32223/wd/hub"), chromeOptions);
driver.get("http://www.google.com");
String pageSource = driver.getPageSource();
log.info(pageSource);
driver.quit();
But I get a This site can't be reached - localhost refused to connect. with
driver.get("http://localhost:8080/health/check");
The same with
driver.get("http://host.docker.internal:8080/health/check");
Or with
driver.get("http://127.0.0.1:8080/health/check");
I didn't find any documentation on how to achieve this kind of setup but any hint is welcome.
I would like to further integrate the selenium testing to my Gitlab CI/CD so I should be able to run the test from a "local" point of view.
Thanks for reading.
I need to start Firefox / Chrome using remote webdriver with a specific browser language. I know how to do it while running locally. But is it possible to start a remote webdriver with specifying browser language.
This is how object creation done is RemoteWebDriver,
WebDriver driver = new RemoteWebDriver(new URL("http://localhost:PORT_NUMBER/"), DesiredCapabilities.firefox());
Profiller is the key here,
var fp = new FirefoxProfile();
fp.SetPreference("intl.accept_languages", "en-au");
desiredCap.SetCapability(FirefoxDriver.ProfileCapabilityName,fp.ToBase64String());
your code seems specific to chrome so you can use this, I hope this might help you,
var options = new ChromeOptions();
options.AddArgument("--lang=zh"); // this sets US english
desiredCap.SetCapability(ChromeOptions.Capability, options);
WebDriver driver = new RemoteWebDriver(new URL("http://localhost:PORT_NUMBER/"), desiredCap.chrome());

From what I understand so far, Chrome Driver always starts without any stored browser cookies.
I need the driver start with all the cookies stored by Chrome.
I wonder if there is any way to start the driver with the cookies that are already stored? I'm using C# with .net 4.5.
Yes we can do it by invoking saved chrome profile just like firefox profile. below are steps i noted when i am doing bit back ago
in Java, we can do it by using ChromeOptions and Chrome Profile. In chrome navigate to chrome://version/ It will display profile path and Executable path.
As per my working on this, The profile path is \Local\Google\Chrome\User Data\Profile 3 This is displaying what is displayed when i navigate to chrome://version/ in normal chrome browser. In this profile, i navigated to stackoverflow and saved credentials. So used below code
Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("binary", "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
System.setProperty("webdriver.chrome.driver", "E:\\selenium_setups\\poi-3.12\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", prefs);
options.addArguments("user-data-dir=C:\\Users\\murali\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 3");
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
WebDriver driver = new ChromeDriver(capabilities);
//WebDriver driver = new ChromeDriver(options);
driver.get("http://stackoverflow.com/");
As per my understanding, i excepted stackoverflow.com page displayed as logged in. but for first time, i am not logged in. so cross checked with chrome://version/ in chrome opened by driver, profile path is displayed as
\Local\Google\Chrome\User Data\Profile 3\Default . then logged manually in that profile it self, which is opened by webdriver and executed gain by closing it.
Finally, page is displayed as logged in. So it may be in java, i hope it will helps you to try in C# .
For Chrome,
public class Chrome {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "E://chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://www.google.com");
}
}
for Firefox,
public class Firefox {
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com");
}
}
Why do we need to specify the system.setProperty for Chrome and IE?
I had also same question, but after digging I found,
WebDriver uses native browser approach. Selenium offers inbuilt
driver for Firefox but not for other browsers. All drivers (Chrome
Driver, IE driver, etc.) are built based on the special JS Engine used
by each browser.
Selenium WebDriver works very well with Mozilla Firefox because it has a built in driver server. But the same is not true for Internet Explorer and Google Chrome. Firefox is the most traditional browser, thus Selenium WebDriver do not require any additional utility to be set before launching the browser. The Selenium package automatically references towards the default location of the firefox.exe, thus the user need not to set any other property.
If you ever get the “the path to the driver executable must be set by the webdriver. ie. driver system property” error or its similarly worded Chrome equivalent, it means that you need to install the driver servers on your browser. The driver server manages the calls between the browsers and the Selenium wire protocol.
The InternetExplorerDriver is a standalone server which implements WebDriver’s wire protocol
Similarly, Google Chrome doesn’t have a built-in server so you will need a Chrome driver server for communicating your Selenium code to the browser. You can download the Chrome driver server.
Founded from here.
Implementation of FirefoxDriver, ChromeDriver, InternetExplorerDriver is different, thus the way of instantiating the object differs as well.
The Firefox Driver controls the Firefox browser using a Firefox plugin. The Firefox Profile that is used is stripped down from what is installed on the machine to only include the Selenium WebDriver.xpi
The InternetExplorerDriver is a standalone server which implements WebDriver’s wire protocol.
The ChromeDriver is maintained / supported by the Chromium project iteslf. WebDriver works with Chrome through the chromedriver binary (found on the chromium project’s download page). You need to have both chromedriver and a version of chrome browser installed. chromedriver needs to be placed somewhere on your system’s path in order for WebDriver to automatically discover it. The Chrome browser itself is discovered by chromedriver in the default installation path
For more details, refer the selenium documentation
Simple answer is, each browser has its own WebDriver implementation and is not maintained by the Selenium project. Hence for selenium to interact with the browser specific driver we need to specify the full path of the driver.
Why for firefox there is no need to specify the driverpath? In Selenium 2.0, selenium RC is still present and was supporting firefox. From Selenium 3.0 onwards there is no official support for any browser specific drivers. Hence, we need to specify the driver path through System.setproperty for all the browsers.
I have a question about selenium2 (webdriver).
As selenium-2 supports following 4 types of web drivers..
1-IE
2-firefox
3-chrome
4-htmlunit
Is there any way to use any other webdriver apart from these; like Safari, Opera etc?
In C# (I think in Java too at least), there is the RemoteWebDriver which is meant to control a WebDriver on a remote machine (although it can be done locally).
RemoteWebDriver can be given a DesiredCapability that has more options. So for example:
RemoteWebDriver operaDriver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), DesiredCapabilities.Opera());
