无法启动Selenium独立服务器

Question

我是Selenium IDE的初学者。添加了插件，并试图运行一个测试用例。它向我显示了下面的错误消息。

[info] Test case failed
[info] Test suite completed: 1 played, 1 failed
[info] Playing test case My First TC
[info] Executing: |open | / | |
[error] Could not connect to Selenium Server. Have you started the Selenium Server yet?

因此，我下载了必要的jar文件，并执行下面的命令java-jar selenium-server-standalone-2.28.0。jar[替换为下载的最新版本]

收到的信息如下：该怎么办？

Usage: <main class> [options]
  Options:
    -browserTimeout
       <Integer> in seconds : number of seconds a browser session is allowed to
       hang (0 means indefinite) while a WebDriver command is running (example:
       driver.get(url)). If the timeout is reached while a WebDriver command is
still processing,
       the session will quit. Minimum value is 60. Default is 0
    -debug
       <Boolean> : enables LogLevel.FINE. Default is false (if omitted)
       Default: false
    -jettyThreads, -jettyMaxThreads
       <Integer> : max number of threads for Jetty. Default is 200
    -log
       <String> filename : the filename to use for logging. If omitted, will log

       to STDOUT
    -port
       <Integer> : the port number the server will use. Defaults to [4444]. When

       "role" is a set to [node], default is [5555]
       Default: 4444
    -role
       <String> options are [hub], [node], or [standalone] : Default is
       [standalone]
       Default: standalone
    -timeout, -sessionTimeout
       <Integer> in seconds : Specifies the timeout before the server
       automatically kills a session that hasn't had any activity in the last X
seconds. The
       test slot will then be released for another test to use. This is typicall
y
       used to take care of client crashes. For grid hub/node roles, cleanUpCycl
e
       must also be set. Default is 1800 (30 minutes)
       Default: 1800

Answer 1

我在启动selenium时也遇到了同样的问题。我通过终止占用4444端口的进程解决了这个问题。

1. netstat-aon|findstr 4444然后可以获取占用端口4444的pid xx。
2. taskkill /T /F /pidxx

Answer 2

这些是几个步骤，你可以申请和检查工程与否

）下载selenium独立jar文件。

2） 将jar文件粘贴到lib文件夹中。

3） 计划-

4） 跑-

5） 为java添加位置和工作目录。exe和selenium独立服务器。罐子

6） 单击变量并添加参数-jar selenium-server-standalone-3.0.1。罐子

7） 点击应用并运行。。。。

8）在Eclipse控制台中，您将获得端口号，这将确认您启动硒独立服务器
