Using Python webdriver Remote to connect to the Java Agent for swing

[Martin-Pierre Roy]

Hello,

        Would anyone have experienced connecting the Python remote webdriver with  Java agent for swing. I did run tests that are inconclusive. 

 I this simple Python code :

szURL = "http://127.0.0.1:44444/"

requested_capabilities = {"browserName": "java", "version": "1.0", "platform": "ANY"}

driver = webdriver.Remote(command_executor=szURL, desired_capabilities=requested_capabilities)

title = driver.title

print(f'Window title is {title}')

driver.quit()

The  result is the following:

selenium.common.exceptions.WebDriverException: Message: Not Implemented: (route is null)

On the server side I get this in the console

Aug 01, 2019 5:02:49 PM net.sourceforge.marathon.javaagent.server.JavaServer serve

INFO: JavaServer.serve(POST //session): {"capabilities": {"firstMatch": [{}], "alwaysMatch": {"browserName": "java", "browserVersion": "1.0", "platformName": "any"}}, "desiredCapabilities": {"browserName": "java", "version": "1.0", "platform": "ANY"}}

   I ran my Python test using the selenium wheel version selenium-3.141.0, but I also ran the test using version 3.8.0, 3.12.0 and the latest 4.0.0a1 with the same result.

I have the equivalent code running in Java and it runs flawlessly.

try {
    String szURL = "http://127.0.0.1:44444";
    RemoteWebDriver driver = new RemoteWebDriver(
            new URL(szURL),
            new DesiredCapabilities("java", "1.0", Platform.ANY)
    );
    String title = driver.getTitle();
    System.out.println("Window title is " + title);
    driver.quit();
} catch(Exception exp){
    System.out.println("Exception occurred while connecting to JavaDriver [ " + exp.getMessage() + " ]");
}

Many thanks for your help,

MP

Hi Martin

We have tried with selenium version '3.13.0' and it worked. Currently marathon doesn't support w3c so the newer versions of selenium won't work.

Please check the url you have given in the python remote WebDriver.

from selenium import webdriver

caps = {"browserName": "java", "version": "1.0", "platform": "ANY"}

driver = webdriver.Remote(command_executor="http://127.0.0.1:53611", desired_capabilities=caps)

print(driver.current_url)

Thanks & Regards

When you say that the project does not support the W3C specification are we talking momentarily the time to implement the up-to-date specification or rather the project Marathon will distance itself from the W3C WebDriver specification?

Thanks,
