无法让 php-webdriver 工作

Question

我要运行都安装automated tests on browserstack which require that the libaries from github.com/facebook/php-webdriver。

我正在开发 Ubuntu 14.04 运行ning Apache2。

我正在按照 GitHub 存储库中的 Get The Code 步骤进行操作，但是当我尝试运行 php composer.phar install 时，我收到了一些警告，提示我缺少软件包和扩展。

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
   see <https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion> for more details.

Read <http://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

可能是我在packagist步骤中没有正确添加依赖？对于这一步，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？

我尝试继续 next step 和运行ning java -jar selenium-server-standalone-2.45.0.jar 但后来我在终端中收到此错误。

关于我对运行 selenium jar 文件的问题的第二部分，我尝试了@acfreitas bellow 建议的解决方案，但仍然收到相同的错误消息。

Answer 1

这里有两个问题：

第一题

您的作曲家无法解析来自 facebook/webdrive 和 minimum stability flags 的依赖项。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/"]
  }
}

和运行

$ php composer.phar install

第二个问题

Selenium 默认端口为 4444。 Exception in thread "main" java.net.BindException: Selenium is already running on port 4444. Or some other service is.表示selenium已经运行ning了。如果你想要运行再次，你可以杀死进程：

$ $ 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

看到 3997 大约是来自 selenium 过程的 pid。更改您的 pid。

或运行 selenium 使用此命令：

$ 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，可以查看doc

Answer 2

只是想评论为什么 GitHub 自述文件页面不建议使用 "minimum-stability"："dev"。因为这样做不好idea/practice

One way to fix the problem would be to just lower your minimum-stability down to "dev". But that's usually a really bad idea, because it applies to all constraints and as a result you will get unstable versions of all packages.

So please, don't do that.
