使用 webdriver 运行 Selenium 服务器

Question

~/tests > uname -a Linux ghopper-K52F 4.10.0-40-generic #44-Ubuntu SMP Thu Nov 9 14:49:09 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

~/tests > apt list --installed | grep openjdk

openjdk-9-jre-headless/zesty,now 9~b161-1 amd64 [installed]

我想用chromedriver启动服务器

~/tests > java -jar -Dwebdriver.chrome.driver=chromedriver selenium-server-standalone-3.7.1.jar

正如我们所见，没有任何关于 webdriver 的提及。 我所有的测试都失败了，浏览器根本没有运行。我在服务器的控制台中得到了日志 sn-p：

Starting ChromeDriver 2.31.488763 (092de99f48a300323ecf8c2a4e2e7cab51de5ba8) on port 8315
Only local connections are allowed.

还有测试的问题：

./vendor/bin/phpunit -v -c tests/phpunit.xml tests/src/Selenium/LoginTest.php
PHPUnit 4.8.36 by Sebastian Bergmann and contributors.

Runtime:        PHP 7.0.22-0ubuntu0.17.04.1
Configuration:  /home/ghopper/work/***/tests/phpunit.xml

ESSSS

Time: 12.19 seconds, Memory: 6.00MB

There was 1 error:

1) Package\Test\Selenium\LoginTest::testUnauthorizedRandomPage
PHPUnit_Extensions_Selenium2TestCase_WebDriverException:

There were 4 skipped tests:

问题：

1. 为什么 Selenium 在没有 webdriver 的情况下运行。
2. 如何调试服务器？错误及其原因在哪里？
3. 如何查看java及其环境？

附：我在另一台 PC 上做同样的事情，对我来说一切正常。我认为问题出在环境中，而不是在服务器的配置中。

现在一切正常！谢谢）
