Run tests using Behat and Mink Selenium2 driver for Microsoft Edge browser in Selenium 4

Question

Is it possible to run tests on Edge browser using Mink Selenium2 driver and Selenium 4 grid ?

I've tried using:

default:
    suites:
      default:
        filters:
          tags: ~@wip
        paths: ['%paths.base%/storage/features']
    gherkin:
      cache: ~
    extensions:
      Behat\MinkExtension:
        base_url: http://www.google.com
        javascript_session: selenium2
        browser_name: edge
        selenium2:
          capabilities:
            browserName: MicrosoftEdge
            browser: edge
            extra_capabilities:
              edgeOptions:
                args:
                  - "--no-sandbox"
                  - "--disable-dev-shm-usage"
                  - "--headless"
                  - "--disable-gpu"
                  - "--dns-prefetch-disable"
                  - "--disable-setuid-sandbox"
                  - "--window-size=1920,1080"
                  - "--remote-debugging-port=9222"

But this gives me some errors saying that the DevToolsActivePort file does not exist:

is there any way to make this work ?

Answer 1

Please make sure you have

127.0.0.1 localhost in your /etc/hosts file.

To check it, you should go to the terminal and run

sudo vi /etc/hosts type your user password and paste

127.0.0.1 localhost to an empty row.

Additionally, please make sure you have ChromeDriver -or the driver of the browser you intend to use- is installed and your program knows the path of ChromeDriver.

You can follow the steps explained here https://www.browserstack.com/guide/run-selenium-tests-using-selenium-chromedriver.

Answer 2

1. For DevToolsActivePort error try another workaround: add --remote-debugging-port=
2. I tried a different version of Selenium server with Edge, including version 4, till version 3.5; it is working fine, and above, it gives different errors. I can see that Selenium 4 is in alpha release at the Maven repository, and all other versions were released in October 2021. I would recommend that you use an earlier version for some time. You can refer to this article for the configuration of Edge with Behat Mink Selenium 2.
