Selenium server does not open browser

Question

I'm trying to get our tried and tested Behat setup to work, but even though Selenium server is up and running, the browser window never opens when I run my script. It seems to be running headless (which it's not supposed to do) but when I check my output file then none of the steps have passed.

I've tried deleting everything and starting from scratch with a fresh pull, but nothing does the trick. Unfortunately I have no idea how I'm supposed to troubleshoot this particular problem so it seems like you guys are my last hope.

I'm guessing my setup would not be of much value since it's already working across multiple other machines but maybe someone has experienced a similar problem and might have a suggestion as to what the error might be. If you need anymore information then please let me know and I'll be happy to provide it.

I use the following when I start Selenium Server:

selenium-server-standalone-2.9.0.jar

chromedriver-2.24

InternetExplorerDriver server (64-bit) 2.53.1.0

Powershell script that I use to start Selenium Server:

Param (
      [string] $FireFoxBinary  
      )
$SeleniumServerPath = (Split-Path -Parent $MyInvocation.MyCommand.Definition) 
if (-not ([String]::IsNullOrEmpty($FireFoxBinary))) {
    $WebDriverFireFoxBin ="""-Dwebdriver.firefox.bin=$FireFoxBinary"""
}
java -jar (Join-Path $SeleniumServerPath "selenium-server-standalone-2.9.0.jar")  "-Dwebdriver.ie.driver=$(Join-Path $SeleniumServerPath IEDriverServer.exe)" "-Dwebdriver.chrome.driver=$(Join-Path $SeleniumServerPath chromedriver-2.24.exe)" $WebDriverFireFoxBin

Console output when starting Selenium server:

please show how you are instantiating the webdriver in your code, and any console output that is displayed. also provide which versions of selenium, the browser, and operating system you are running. Your original question is verbose but contains absolutely no information that can be used to help you. — Corey Goldberg
You should add at least something, some error, profile from behat.yml. If absolute everything in the setup is the same then the selenium server might be the issue, maybe different driver or different browser version. — lauda
I've updated my original post with some more information about my setup. Unfortunately I don't get an error, so I can't post any information regarding that. If you need even more information then I'll update as soon as possible. — Test monkey

One thing that helps a lot of people who've encountered your sort of problem is maximizing the browser. Even a headless browser needs room to render. I just use:

driver.manage().window().maximize();

You should also try to take a screenshot immediately after the first driver.get().
