php - 浏览器 “DevToolsActivePort file doesn' t 存在的 Dusk 测试”

Question

我正在为浏览器运行 Laravel Dusk 的示例测试，但是当我执行 php artisan dusk 时出现错误

使用:* Ubuntu 18* 拉维尔 5.8*黄昏5.1* Chrome 驱动程序 74* Apache 2

这是我的 DuskTestCase.php:

    <?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;

/**
 * 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()
{
    $options = (new ChromeOptions)->addArguments([
        '--disable-gpu',
        '--headless',
        '--window-size=1920,1080',
        '--disable-dev-shm-usage',
        '--no-sandbox'
    ]);

    return RemoteWebDriver::create(
        'http://localhost:9515', DesiredCapabilities::chrome()->setCapability(
            ChromeOptions::CAPABILITY, $options
        )
        // 'http://localhost:9515', DesiredCapabilities::phantomjs()
        // 'http://localhost:9515', DesiredCapabilities::chrome()
    );
}

这是错误:

    1) Tests\Browser\ExampleTest::testBasicExample
    Facebook\WebDriver\Exception\UnknownServerException: unknown error: Chrome failed to start: exited abnormally
      (unknown error: DevToolsActivePort file doesn't exist)
      (The process started from chrome location /snap/bin/chromium is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
      (Driver info: chromedriver=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Linux 4.18.0-20-generic x86_64)

在我的例子中，我发现我需要将 --no-sandbox 添加到 tests/DuskTestCase.php，因为我在 lxd 容器上以根目录运行.

我通过运行发现错误:vendor/laravel/dusk/bin/chromedriver-linux --log-level=ALL 并在另一个终端运行 php artisan dusk。它将显示日志，我能够从那里推断出问题。
