Eclipse + Java + Selenium creates ClassNotFoundException

just getting started with Eclipse + Java + Selenium.

Not doing anything fancy -

My code looks like this:

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


When I run, I get a ClassNotFoundException.

I have selenium-java-2.48.2.jar in my Java Build Path.

What am I missing?

Can you add your stacktrace, so I could see the full exception messge.

You need download Chromedriver first, once you download it, place executable inside your project and set chromedriver property, it should be something like:

project_folder
- src
- chromedriver.exe

System.setProperty("webdriver.chrome.driver", "chromedriver.exe");
WebDriver driver = new ChromeDriver();


Tried all that, didn't help: public class TestApp { public static void main(String args) { System.setProperty("webdriver.chrome.driver", "chromedriver.exe"); WebDriver driver = new ChromeDriver(); driver.get("google.com"); } }

Is there test runner in place, JUnit or TestNG?

I see now, you missing test runner (just use JUnit or TestNG) and annotate your test methods with @Test tag, also keep your tests in src/test not in src/main.

okay, so I am going to install JUNIT based on junit.sourceforge.net, unzip junit*.jar to some directory, setup environment variable CLASSPATH to include that.

String WEB_DRIVER_PATH="";
String url=URL_TO_HIT_ON_BROWSER;

System.setProperty("webdriver.chrome.driver", WEB_DRIVER_PATH);
driver=new ChromeDriver();
driver.get(url +"/");


use updated jars.

try this:

WebDriver driver = new ChromeDriver();

@Test
public void goToWebsite() {
driver.get("http://www.google.com");
}


and then run goToWebsite

I am not sure if you are using 2.XX version of selenium because the problem you are facing is the same i faced when i moved my existing scripts from selenium 2 to Selenium 3.
You need to set the path of the chromedriver first.
Steps-
1. Download chromedriver.exe compatible for your environment.
2. Set the path of chromedriver.Add the following line of code before making ChromeDriver object.

System.setProperty("webdriver.chrome.driver", "chromedriver.exe");


Check if your class file is in a source folder. If it is not, right click on the folder, choose Build Path > Use as source folder

Make sure all your jars are in the build path. I also suggest that you use Maven to help you organize jars as dependencies

After these, you must download the chromedriver.exe file from here:
http://chromedriver.chromium.org/downloads

Place the chromedriver.exe file in any accessible directory and set the web driver environment property by inserting this line on your code before instantiating your driver:

System.setProperty("webdriver.chrome.driver", "<pathToYourDriver>/chromedriver.exe");
