使用Robot Framework执行selenium示例时出错

Question

在我的系统上，我安装了Python 2.6和Robot框架。我已经按照下面的链接安装了Selenium2Library：https://github.com/rtomac/robotframework-selenium2library，但当我尝试运行这个例子时，它给了我以下错误信息，并且没有打开firefox窗口。

ERROR:  clean-python26-env]$ python testExeJS.py 
======================================================================
ERROR: test_exe_javascript (__main__.ExecuteJavascriptTestCase)
----------------------------------------------------------------------

Traceback (most recent call last):
  File "testExeJS.py", line 7, in setUp
    selenium.setTimeout("60000")
NameError: global name 'selenium' is not defined

----------------------------------------------------------------------
Ran 1 test in 0.000s

FAILED (errors=1)

任何帮助都是非常感谢的

很抱歉，我刚看到你的回复。也许这会帮助你更好地理解我的问题。示例代码链接为：`http://www.wallix.org/2011/07/26/how-to-use-robotframework-with-the-selenium-library/

我的运行错误是：

$ pybot myFirstTest.txt 

==============================================================================

好的，在这里，我将对日志进行注释，希望您将来可以看到如何读取它并从中进行调试。我为任何不准确的地方道歉，因为我已经习惯了Selenium2Library：

$ pybot myFirstTest.txt 
==============================================================================
myFirstTest :: This is your first test                                        
==============================================================================
[ WARN ] Keyword 'Capture Page Screenshot' could not be run on failure: No browser is open

好的，这是你的第一条线索- selenium正在尝试截图，但是没有看到浏览器打开-你看到浏览器打开了吗？它是否打开到正确的页面？

Go To Google Page [Documentation] Go to google page and search som... | FAIL |
WebDriverException: Message: 'The browser appears to have exited before we could connect. The output was: Error: no display specified\n'

所以这里是下一个线索- The browser appears to have exited before we could connect. The output was: Error: no display specified -这表明问题是你在无头运行，SeleniumLibrary希望找到一个显示器(如果我错了请纠正我)，所以你可能需要创建一个显示器，这比听起来要简单得多-你会想要安装PyVirtualDisplay，然后从robotframework -在使用| Library | pyvirtualdisplay.smartdisplay.SmartDisplay |之前尝试使用SeleniumLibrary。

------------------------------------------------------------------------------
[ WARN ] Keyword 'Capture Page Screenshot' could not be run on failure: No browser is open

这又是第一条线索。

Open Selenium Page [Documentation] TestCase for open Selenium page    | FAIL |
No browser is open

这是因为之前的问题。
