Laravel Sail + Dusk + Selenium：连接被拒绝

Question

我有一个带有 Sail 的 Laravel，我想用 Laravel Dusk 进行自动化测试。我按照Dusk Documentation和Sail + Dusk Installation中的所有说明进行操作，但是当我运行默认测试时，我收到以下错误消息：

Tests\Browser\ExampleTest::testBasicExample
Facebook\WebDriver\Exception\WebDriverCurlException: Curl error thrown for http POST to /session with params: {"capabilities":{"firstMatch":[{"browserName":"chrome","goog:chromeOptions":{"args":["--disable-gpu","--headless","--no-sandbox","--window-size=1920,1080"]},"acceptInsecureCerts":true}]},"desiredCapabilities":{"browserName":"chrome","platform":"ANY","chromeOptions":{"args":["--disable-gpu","--headless","--no-sandbox","--window-size=1920,1080"]},"acceptInsecureCerts":true}}

Failed to connect to localhost port 4444: Connection refused

但如果在 Insomnia 中执行请求，它运行不会出现任何问题：

失眠请求

这是我的 docker-compose：

还有我的 DuskTestCase

<?php

namespace Tests;

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

abstract class DuskTestCase extends BaseTestCase {
    use CreatesApplication;

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

    /**
     * Create the RemoteWebDriver instance.
     *
     * @return \Facebook\WebDriver\Remote\RemoteWebDriver
     */
    protected function driver() {
        $options = (new ChromeOptions)->addArguments([
            '--disable-gpu',
            '--headless',
            '--no-sandbox',
            '--window-size=1920,1080',
        ]);

        return RemoteWebDriver::create(
            'http://localhost:4444/wd/hub', DesiredCapabilities::chrome()->setCapability(
            ChromeOptions::CAPABILITY, $options
        )->setCapability('acceptInsecureCerts', TRUE)
        );
    }
}

我真的不知道我做错了什么。抱歉我的英语不好，我是巴西人。

经过很多天我终于成功解决了我的问题。阅读Docker 文档后，我发现我可以使用镜像名称作为 URL，因此我切换到 http://selenium:4444 并且测试完美运行！

这是我的新代码：

<?php

namespace Tests;

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

abstract class DuskTestCase extends BaseTestCase {
    use CreatesApplication;

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

    /**
     * Create the RemoteWebDriver instance.
     *
     * @return \Facebook\WebDriver\Remote\RemoteWebDriver
     */
    protected function driver() {
        $options = (new ChromeOptions)->addArguments([
            '--disable-gpu',
            '--headless',
            '--no-sandbox',
            '--window-size=1920,1080',
        ]);

        return RemoteWebDriver::create(
            'http://selenium:4444/wd/hub', DesiredCapabilities::chrome()->setCapability(
            ChromeOptions::CAPABILITY, $options
        )->setCapability('acceptInsecureCerts', TRUE)
        );
    }
}

我希望我可以帮助有同样问题的人！
