I'm trying to install and run Selenium WebDriver using Java on a Mac. My favourite IDE is IntelliJ IDEA. When I try this:

public class TestImplWithoutWebDriverManager implements TestingConstants
{
static public void main(String... args)
{
String chromeDriverLibPath = "./lib/chromedriver";
File chromeDriverLib = new File(chromeDriverLibPath);
System.out.println(chromeDriverLib.exists());
System.out.println(chromeDriverLib.canRead());
System.setProperty("webdriver.chrome.driver", chromeDriverLibPath);
ChromeDriver chromeDriver = new ChromeDriver();
chromeDriver.navigate().to(MyTestHomePage);
}
}

I get this console output:

true
true
Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

What am I missing out?

This is very confusing. How do you go from:

ChromeDriver chromeDriver = new ChromeDriver();

to:

at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:106)
at TestImplWithoutWebDriverManager.main(TestImplWithoutWebDriverManager.java:26)

Show the other 26 lines of your code.

Hi SiKing

Thanx for your note. I have to correct my console output. There it says something about a FirefoxDriver which is not addressed in the source code at all. The console output and the source code were not in sync. Here's the correct source code:

import framework.TestingConstants;
import org.openqa.selenium.chrome.ChromeDriver;

import java.io.File;

public class TestImplWithoutWebDriverManager implements TestingConstants
{
static public void main(String... args)
{
String chromeDriverLibPath = "./lib/chromedriver";
File chromeDriverLib = new File(chromeDriverLibPath);
System.out.println(chromeDriverLib.exists());
System.out.println(chromeDriverLib.canRead());
System.setProperty("webdriver.chrome.driver", chromeDriverLibPath);
ChromeDriver chromeDriver = new ChromeDriver();
chromeDriver
.navigate()
.to(MyTestHomePage);
}
}

and the correct console output:

true
true
Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

1. Check whether mentioned Correct driver exe path.

2. keep the Path till extension like ./lib/chromedriver.exe

3. make sure downloaded the correct version of the exe file to match your local chrome browser.

I suggest overcoming all these steps using the WebDriverManager opensource project.

WebDriverManager.chromedriver().setup();
WebDriver driver= new ChromeDriver();

public class TestImplWithoutWebDriverManager implements TestingConstants

As an initial experiment can you drop implementing TestingConstants, since I have no idea what that is.

Also, what do you get if you manually run ` ./lib/chromedriver --version` from the commandline?

Hi Veena

Many thanx for your reply.

To 1: The file path is ok. That's what the two "true" in the console output show. They show whether the lib file is there and whether it is readable.

To 2: There are no ".exe" extensions since this is a Macintosh computer, not a windows computer:

... where the content of the .lib folder is:

-rwxr-xr-x@ 1 lemmi staff 17775332 Jun 4 2013 chromedriver

-rwxr-xr-x@ 1 lemmi staff 4261264 Sep 16 11:55 geckodriver
-rwxr-xr-x@ 1 lemmi staff 18016880 Mar 10 08:06 msedgedriver

To 3: I downloaded the files a couple of days ago from https://www.selenium.dev/documentation/webdriver/getting_started/install_drivers/
They are up-to-date.

WebDriverManager: Due to security policy, it is not possible to let a class get stuff from the internet. The libs must already be in place locally.

ACK. TestingConstants is a part of my testing suite. It can easily be omitted, only then the Constant "MyTestHomePage" in the very last line of code must be replaced by an existing URL String.

Hm... when I run "./lib/chromedriver --version", he says:

zsh: bad CPU type in executable: lib/chromedriver

What does that mean?

Sounds like you are on a MAC.

Can you just use brew to install chromedriver ? That would also ensure that the binary is automatically added to your PATH variable and you don't need to be doing anything extra.

You may have to restart your IDE after installing chromedriver via homebrew

https://brew.sh/

https://formulae.brew.sh/cask/chromedriver

After installing try just running chromedriver. You should see something like this.

~ chromedriver
Starting ChromeDriver 99.0.4844.51 (d537ec02474b5afe23684e7963d538896c63ac77-refs/branch-heads/4844@{#875}) on port 9515
Only local connections are allowed.
Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
ChromeDriver was started successfully.

Thanks & Regards

This means you found your problem! You installed an invalid/corrupted executable.

You can install the correct one from here https://chromedriver.chromium.org/downloads

Or follow the advice from Krishnan Mahadevan.

Good luck.

All fine. Now it works as expected!

At first I installed Homebrew and with it then chromedriver. It worked.

Then I downloaded from <chromedriver.storage.googleapis.com/index.html?path=99.0.4844.51> the 64-bit-version of the chromedriver, put it into my ./lib folder and it worked as well.
