Grid : Is chromedriver binary file not required when running the test in same machine

[Vignesh Ramesh]

I am using selenium grid to run test in chrome browser . when i am using my PC as both selenium hub and node. My selenium script is running successfully without setting the path for chrome binary file.

sample code

           

 DesiredCapabilities capabilities = DesiredCapabilities.chrome();
 
 capabilities.setBrowserName("chrome");
 
 capabilities.setPlatform(Platform.LINUX);
 
 driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capabilities);

 driver.get("http://www.google.co.in");

But when i create a webdriver instance  instead of RemoteWebDriver

                  

   WebDriver driver = new ChromeDriver();
     
   driver.get("http://www.google.com");

I get an error message The path to the driver executable must be set by the webdriver.chrome.driver system property;

Can anyone explain me why the test is working fine without an binary file in the first case

Any help is greatly appreciated

I dont think that's the case. You will see the error message that you have called out in the second case under the following conditions :

* The chromedriver binary cannot be found in all the folders as detailed by the PATH environment variable.

* Webdriver tried querying the JVM argument webdriver.chrome.driver and found an empty value.

This behavior is the same across both RemoteWebDriver and ChromeDriver because RemoteWebDriver internally doesn't do much apart from using reflection to make a call to ChromeDriver only to get the job done.

Thanks & Regards
