可以'；t让php-webdriver工作

Can't get php-webdriver to work

本文关键字：php-webdriver 工作 可以 | 更新日期: 2023-09-27

我想在browserstack上运行自动化测试，这需要安装github.com/facebook/php-webdriver中的库。

我在Ubuntu 14.04上运行Apache2。

我正在遵循GitHub repo中的"获取代码"步骤，但当我尝试运行php composer.phar install时，我会收到一些警告，说我缺少包和外部。

php-webdriver: (master)$ php composer.phar install

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting

也许我没有正确地在包装步骤中添加依赖项？在这一步中，我将composer.json文件更新为：

{
  "name": "facebook/webdriver",
  "description": "A php client for WebDriver",
  "keywords": ["webdriver", "selenium", "php", "facebook"],
  "homepage": "https://github.com/facebook/php-webdriver",
  "type": "library",
  "license": "Apache-2.0",
  "support": {
    "issues": "https://github.com/facebook/php-webdriver/issues",
    "forum": "https://www.facebook.com/groups/phpwebdriver/",
    "source": "https://github.com/facebook/php-webdriver"
  },
  "require": {
    "php": ">=5.3.19",
    "facebook/webdriver": "dev-master"
  },
  "require-dev": {
    "phpunit/phpunit": "3.7.*",
    "phpdocumentor/phpdocumentor": "2.*"
  },
  "autoload": {
    "classmap": ["lib/"]
  }
}

我是否正确添加了"facebook/webdriver": "dev-master"行？

我试着继续下一步并运行java -jar selenium-server-standalone-2.45.0.jar，但后来在终端中出现了这个错误。

关于我问题的第二部分，即运行硒罐文件，我尝试了@acfreitas bellow建议的解决方案，但仍然收到了相同的错误消息。

这里有两个问题：

第一个问题

您的composer无法解析facebook/webdrive和最低稳定性标志的依赖关系。添加"minimum-stability": "dev"

{
  "name": "facebook/webdriver",
  "description": "A php client for WebDriver",
  "keywords": ["webdriver", "selenium", "php", "facebook"],
  "homepage": "https://github.com/facebook/php-webdriver",
  "type": "library",
  "license": "Apache-2.0",
  "support": {
    "issues": "https://github.com/facebook/php-webdriver/issues",
    "forum": "https://www.facebook.com/groups/phpwebdriver/",
    "source": "https://github.com/facebook/php-webdriver"
  },
  "minimum-stability": "dev",
  "require": {
    "php": ">=5.3.19",
    "facebook/webdriver": "dev-master"
  },
  "require-dev": {
    "phpunit/phpunit": "3.7.*",
    "phpdocumentor/phpdocumentor": "2.*"
  },
  "autoload": {
    "classmap": ["lib/"]
  }
}

并运行

$ php composer.phar install

第二个问题

端口默认的Selenium是4444。Exception in thread "main" java.net.BindException: Selenium is already running on port 4444. Or some other service is.说硒已经在运行。若你们想再次运行，你们可以终止进程为：

$ $ ps aux | grep selenium
root   3997  2.6  3.2 465024 33336 pts/0    Sl+  15:40   0:00 java -jar selenium-server-standalone-2.45.0.jar
$ kill -9 3997

请参阅3997是关于硒过程的pid。更改你的pid。

或者使用以下命令运行selenium：

$ java -jar selenium-server-standalone-2.45.0.jar -role hub -port 4441

因此，您应该在测试中编辑主机端口。更多信息，您可以查看文档

我只是想评论一下为什么GitHub Readme页面不建议使用"最低稳定性"："dev"。这是因为这样做是个坏主意/坏做法

解决问题的一种方法是降低最低稳定性降至"dev"。但这通常是一个非常糟糕的主意，因为它适用于所有约束，因此您将得到所有包的不稳定版本。

所以请不要那样做。
