使用 Laravel Sail 运行 Laravel Dusk 时连接被拒绝 docker-compose.yml.env.duskdatabase.phpDuskTestCase.php

问题描述

我正在尝试使用与 Laravel Sail 集成的 Laravel Dusk，如下所述：https://laravel.com/docs/8.x/sail#laravel-dusk

我在完成这项工作时遇到了一些问题：

• 如果使用 .env.dusk 或 .env.dusk.local 文件并使用“sail dusk”运行测试，我会收到连接拒绝错误（更多详细信息见下文）

• 例如，如果使用 .env.testing 来设置 ENV 变量并运行“sail dusk --env=testing”，则连接拒绝错误消失，但应用程序继续使用默认的 .env 文件，同时dusk 测试使用 .env.testing，导致很多错误。

docker-compose.yml

    use CreatesApplication;

    /**

     *

     * @return void
     */
    public static function prepare()
    {
        if (! static::runningInSail()) {
            static::startChromeDriver();
        }
    }

    /**
     * Create the RemoteWebDriver instance.
     *

    protected function driver()
    {
        $options = (new ChromeOptions)->addArguments([
            '--disable-gpu','--headless','--window-size=1920,1080',]);

        return RemoteWebDriver::create(
            $_ENV['DUSK_DRIVER_URL'] ?? 'http://localhost:9515',DesiredCapabilities::chrome()->setCapability(
                ChromeOptions::CAPABILITY,$options
            )
        );
    }
}

当我运行 'sail dusk' 时，出现以下错误：

解决方法

尝试使用

APP_URL=http://laravel.test

由于测试是在 selenium docker 中运行的，这会引用回您的 Laravel docker 容器。
