Getting a strange error out of the blue in a Cucumber framework that uses Selenium and Chromedriver

I have two different automation frameworks that both make use of the Chrome driver. These frameworks do not exactly directly access Selenium (they are Appian based) but I have suddenly (beginning today) found that none of my tests work and I get the same error every time. I am sure that the driver is up to date.

org.openqa.selenium.remote.http.ConnectionFailedException: Unable to establish websocket connection to http://localhost:50576/devtools/browser/12acb1c1-5b1c-46c2-7501-a8958019eb0f

To give a little bit of context the Appian framework handles the Selenium driver in a back-end class/method that I have no control over known as "CucumberBaseFixture."

Within my Cucumber step definitions I simply call the driver like such

Given I setup with "CHROME" browser

as Appian has already created all of the step definitions within their automation framework jar.

Further, I actually set the URL directly using another pre-configured step as such (I have redacted the exact URL due to corporate security.

And I set Appian URL to "REDACTED BUT 100% VALID URL"

I have verified that my necessary configuration is correct for the driver which is not difficult considering they have a script that sets the configuration parameter for you.

Once I execute the test then I get the following stack as well which I find interesting and then the chrome window opens for a moment, closes and the test ends.

ChromeDriver was started successfully.

Thank you for any help.

Solution

  • After a very long investigation including opening a ticket with the link Daniel shared and then looking into a still unresolved Selenium bug, I was able to locate a comment with the current workaround.

    First, you must declare the following in your POM:

       <dependency>
  <groupId>org.seleniumhq.selenium</groupId>
  <version>4.8.1</version>
  <artifactId>selenium-http-jdk-client</artifactId>
</dependency>

    Second, you must add the following line of code to your framework. I put mine in my Junit @BeforeClass in my Cucumber TestRunner:

    System.setProperty("webdriver.http.factory", "jdk-http-client");

    I hope this helps anyone with similar problems.
