In order to execute test scripts on diff browsers, we download specific browser driver from seleniumhq.com and run the scripts.
This code works fine as it should:
System.setProperty("webdriver.ie.driver", "C:\\Users\\Public\\CIO\\resources\\iedriver.exe");
WebDriver driver = new InternetExplorerDriver();
driver.get("www.mywebsite.com");
When I already have IE Executable -'iexplore.exe' on my machine, can't selenium webdriver use that to launch IE?
Why do we specifically download IEDriver from seleniumhq.com here?
C:\Program Files\Internet Explorer\iexplore.exe
I tried to even setup that up and ran the program. Browser got launched with address as --port=1234/ however it could not navigate to respective website and eventually threw exception:
Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException:
Could not start a new session. Possible causes are invalid address of the remote server or
browser start-up failure.

The "Browser Drivers" are servers that implement the WebDriver's wire protocol, and know how to convert those commands into the specific browser's proprietary native API.
The WebDriver site explains:
Selenium-WebDriver makes direct calls to the browser using each
browser’s native support for automation. How these direct calls are
made, and the features they support depends on the browser you are
using.
For example, the ChromeDriver wiki describes it as follows:
The ChromeDriver consists of three separate pieces. There is the
browser itself ("chrome"), the language bindings provided by the
Selenium project ("the driver") and an executable downloaded from the
Chromium project which acts as a bridge between "chrome" and the
"driver".
Essentially, the browser doesn't know how to "talk" WebDriver Wire Protocol, and the WebDriver doesn't know how to "talk" Browser API. In fact, each Browser has its own native API. The "browser driver" knows how to interpret the Wire Protocol and invoke that browser's API.

I am having trouble in using headless chrome on jenkins remote server. the test is failed at the time of url invoking or takes to much of a time like 5+mins and test failed as it wont have waiting time for that long, i have tried different chromeoption like disable gpu, nosandbox etc still the issue is not solved.There is no issue in opening those url in normal mode but its not working on headless mode. i am using this chromeoptions for test:
enter code here
``` chromeOptions.addArguments("--window-size=1366,768");
chromeOptions.addArguments("--disable-gpu");
chromeOptions.addArguments("--disable-extensions");
chromeOptions.addArguments("--proxy-server='direct://'");
chromeOptions.addArguments("--proxy-bypass-list=*");
chromeOptions.addArguments("--start-maximized");
chromeOptions.addArguments("--headless");
chromeOptions.addArguments("no-sandbox", "--disable-infobars", "--disable-dev-shm-usage", "--disable-browser-side-navigation",
"--ignore-certificate-errors");```
I have Hybrid Framework using Selenium Webdriver that successfully executes test cases against Firefox, Chrome and IE. Now, I wanted to run this entire suite using Browserstack.
However, when I try to access the application I make entries in the host file - the ipaddress and the host name. This makes sure that I'm hitting the exact server.
Using Java code on https://www.browserstack.com/automate/java I'm able to execute a sample script.
However, how can I pass the ipaddress mapping of my application to my Selenium instance when executing it on Browserstack?
The BrowserStack Local Testing feature (https://www.browserstack.com/local-testing) should help you test your private servers configured in your hosts file. Please follow these steps:
1) Download and execute the Local Testing binaries (https://www.browserstack.com/local-testing#command-line) using the following command:
./BrowserStackLocal ACCESS_KEY -forcelocal
The '-forcelocal' parameter will route all traffic via your machine which allows you to test servers configured in your hosts file on BrowserStack.
2) Add the capability 'browserstack.local'='true' in your test scripts and execute them.
I'm trying to run some Selenium tests for an application while it is started, but am getting a runtime exception:
Could not start Selenium session: HTTP method POST is not supported by this URL
The application we made has no need for a POST method. Is there any way to make Selenium work without needlessly implementing one? Why is it required in the first place?
The parameters to pass for DefaultSelenium are as follows according to the api documentation:
serverHost - the host name on which the Selenium Server resides
serverPort - the port on which the Selenium Server is listening
browserString - the command string used to launch the browser
browserURL - the starting URL including just a domain name
You need to direct it to where an instance of your selenium server is running (which could be remotely or locally). I am going to guess that localhost:8080 is where you have deployed a separate application that you want to test with selenium.
So, the details you provide are for the selenium server, not for your application. If you download the standalone server and run it locally, you only need to change the port to match that of the selenium server instance. You can download the selenium standalone server from their main website, and when you run it, it will tell you the port that it uses (by default it is 4444).
Why not just use WebDriver instead?
WebDriver driver = new FirefoxDriver();
driver.get("URL")
You can read more about how to use it on the documentation page on the selenium website.
I m using Selenium IE Webdriver.I want to delete "This is the initial page of webdriver server." from IEDriverServer.exe file of Selenium IE Webdriver. I opened the IEDriverServer.exe file in notepad++ and deleted that line from it and again add it in my classpath.But then i get this error:
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
How can we do that.Please someone tell me.
You can't just edit an executable file like that. You have undoubtedly ruined the executable and now should redownload it from the Selenium site.
Regardless, this is expected behaviour. The IEDriver must have somewhere to go to begin with.
There is a setting that configures this URL called InitialBrowserURL. If this is not configured in your code, then the default is used.
Configure this to what you want. Most cases it can be configured to just go to the home page of your application.
In the selenium download page, I see a section "Selenium Client & WebDriver Language Bindings"
1) What is a Language Binding? and
2) What is a Client Driver?
(I am not from from a technical background)
Can someone please explain the following taken from selenium download page :(http://docs.seleniumhq.org/download/)

In order to create scripts that interact with the Selenium Server
(Selenium RC, Selenium Remote Webdriver) or create local Selenium
WebDriver script you need to make use of language-specific client
drivers. These languages include both 1.x and 2.x style clients. While
language bindings for other languages exist, these are the core ones
that are supported by the main project hosted on google code.
*
Some of that documentation is old. It comes from the old Selenium 1.x versions. Selenium WebDriver is much different now, with 2.x versions (the latest being 2.31). Selenium 2.x versions have bindings hidden from your view. You define capabilities and start a new RemoteWebDriver and the Hub+Node handles the binding under the covers.
Now, to interact similar to RC you need:
1. To start a Grid Hub on port 4444
2. Start 1 Node Hub on port 5555 on either your local machine or a remote machine. It has configuration that tells it how to connect to the Hub.
3. In your script, start a new client using:
URL hubURL = new URL("127.0.0.1:4444"); // always use IP address
DesiredCapabilities capability = DesiredCapabilities.internetExplorer();
RemoteWebDriver driver = new RemoteWebDriver(new URL(hubURL), capability);
I have an example project you can try here.
2) What is a Client Driver?
Selenium uses many client drivers java,python.... so to work with each programming language there is a different driver.This is nothing but a JAR in my understanding.
