Grails - Selenium-RC插件-启动Selenium服务器

Question

我正在尝试通过Selenium-RC插件在我的Grails项目中设置Selenium。然后，我运行了grails install-plugin selenium-rc命令。

然后，我运行了grails create-selenium-test firstTest命令，并在其中添加了以下内容：

import grails.plugins.selenium.*
import org.junit.*
import static org.junit.Assert.*
import static org.hamcrest.Matchers.*

@Mixin(SeleniumAware)
class FirstTestTests {
    @Before void setUp() {
    }

    @After void tearDown() {
        super.tearDown()
    }

    @Test void something() {
        selenium.open "/"
        assertTrue selenium.isTextPresent("Bem vindos")
    }
}

当我在Ubuntu 11.04上运行测试时，Grails启动了默认的firefox浏览器(8.0版)，但在将以下内容打印到控制台输出后在此处冻结：

    Server running. Browse to http://localhost:8080/
  [groovyc] Compiling 1 source file to /home/alessandro/Documents/[...]/target/test-classes/selenium
Starting Selenium server on port 4444 ...
Starting Selenium session for http://www.mywebsite.com/ ...

当我通过Ctrl + C中断测试时，它抛出以下错误消息：

    Error running selenium tests: java.lang.RuntimeException: Could not contact Selenium Server; have you started it on 'localhost:4444' ?

我已经阅读了插件文档，其中说服务器是由插件启动的，在测试冻结之前，它由控制台输出作为支持。我真的不知道下一步该怎么做。我浏览过网页，但我找到的唯一一条建议是将selenium-server.jar添加到java path中，这似乎已经被插件覆盖了。

非常感谢您的帮助。

Answer 1

我也有同样的问题--你可以看看我的question。我猜问题出在火狐上--我把它改成了Chrome，它开箱即用。你只需要替换掉

  browser = "*firefox"

使用

  browser = "*googlechrome" 

在SeleniumConfig中

Answer 2

非常感谢。它就像你说的那样有效。对于那些在Ubuntu下也使用Chromium的用户，下面是我添加来配置SeleniumConfig文件的内容：

browser = "*googlechrome /usr/lib/chromium-browser/chromium-browser"

现在我明白了：

    Stopping Selenium server ...

当测试通过后。我会调查一下的。感谢mkk
