Connection Refused : Failed to connect to 127.0.0.1 port 4444: Connection refused laravel dusk with selenium and laradock

Question

I am using laradock https://github.com/laradock/laradock for development environment setup. Everything looks good untill I have tried to run dusk test in the environment.

This is the output of command php artisan dusk

root@e686e0cbda43:/var/www/stability_v54# php artisan dusk --filter test_WhenEmptyFormIsSubmitted_ShowErrorMessages 
PHPUnit 6.5.14 by Sebastian Bergmann and contributors.

E                                                                   1 / 1 (100%)

Time: 28.59 seconds, Memory: 34.00MB

There was 1 error:

1) Tests\Browser\NurseRegisterTest::test_WhenEmptyFormIsSubmitted_ShowErrorMessages
Facebook\WebDriver\Exception\WebDriverCurlException: Curl error thrown for http POST to /session with params: {"desiredCapabilities":{"browserName":"chrome","platform":"ANY","chromeOptions":{"w3c":false,"binary":"","args":["--disable-gpu","--no-sandbox","--ignore-ssl-errors","--whitelisted-ips=\"\"","--headless"]}}}

here is DuskTestCase,

<?php

namespace Tests;

use Laravel\Dusk\TestCase as BaseTestCase;
use Facebook\WebDriver\Chrome\ChromeOptions;
use Facebook\WebDriver\Remote\RemoteWebDriver;
use Facebook\WebDriver\Remote\DesiredCapabilities;

abstract class DuskTestCase extends BaseTestCase
{
    use CreatesApplication;

    protected function setUp()
    {
        //Set wait env variables
        $this->quickWait  = env('QUICK_WAIT', false);
        $this->shortWait  = env('SHORT_WAIT', false);
        $this->mediumWait = env('MEDIUM_WAIT', false);
        $this->longWait   = env('LONG_WAIT', false);

        parent::setUp();

        foreach (static::$browsers as $browser) {
            $browser->driver->manage()->deleteAllCookies();
        }
    }

    /**
     * Prepare for Dusk test execution.
     *
     * @beforeClass
     * @return void
     */
    public static function prepare()
    {
        static::startChromeDriver();
    }

    /**
     * Create the RemoteWebDriver instance.
     *
     * @return \Facebook\WebDriver\Remote\RemoteWebDriver
     */
    protected function driver()
    {
        $arguments = [
            '--disable-gpu',
            '--no-sandbox',
            '--ignore-ssl-errors',
            '--whitelisted-ips=""',
        ];

        $headlessMode = env('DUSK_HEADLESS_MODE', false);

        if($headlessMode) {
            array_push($arguments, '--headless');
        }

        $options = (new ChromeOptions)->addArguments($arguments);

        return RemoteWebDriver::create(
            'http://127.0.0.1:4444', DesiredCapabilities::chrome()->setCapability(
                ChromeOptions::CAPABILITY, $options
            )
        );
    }
}

I have following version of chrome driver and selenium.

Chrome version 88.0.4324.96 Selenium Standalone v.3.141.59

Somewhere I found I have to update these two into latest version, but these are already latest ones in my setup.

This question may sound duplicate but I have already tried the available ones in this community.

If somebody know the reason behind this please share, it will be extremly helpful.

The Curl error thrown for POST... means your dusk test case was unable to connect with the selenium endpoint entirely.

I see that you used 127.0.0.1 in your driver setup

protected function driver() {
    return RemoteWebDriver::create('http://127.0.0.1:4444', ...

but, assuming you're running php artisan dusk inside your laradock workspace container, that container can't see the seleninum host at http://127.0.0.1. However, because of the frontend network set up between containers by docker compose, that container can see it at http://selenium

Also, I think you also need to specify path /wd/hub under selenium

So try this:

return RemoteWebDriver::create('http://selenium:4444/wd/hub', ...
Run dusk inside your laradock workspace container, e.g.
docker-compose exec -u laradock workspace php artisan dusk
