使用 Robot Framework 执行 selenium 示例时发生错误

Question

在我的系统上，我有 Python 2.6 和 Robot 框架。我已经按照以下链接的说明安装了 Selenium2Library： https://github.com/rtomac/robotframework-selenium2library 但是当我尝试运行该示例时，它给了我以下错误并且没有打开任何 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)

任何帮助真的很感激

对不起，我刚刚看到你的回复。可能这将帮助您更多地了解我的问题。 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，所以我将在这里对日志进行注释，以便您将来可以看到如何阅读它并从中进行调试。对于任何不准确之处，我深表歉意，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，这是您的第一个线索 - selenium 正在尝试截取屏幕截图，但没有看到打开的浏览器 - 您看到打开的浏览器了吗？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'

所以这是下一个线索 - The browser appears to have exited before we could connect. The output was: Error: no display specified - 所以这表明问题是你正在无头运行，而 SeleniumLibrary 期望找到一个显示（如果我错了，请纠正我）所以你可能需要创建一，这比听起来容易得多 - 您需要安装PyVirtualDisplay，然后从robotframework - 在使用SeleniumLibrary之前尝试使用| Library | pyvirtualdisplay.smartdisplay.SmartDisplay |。

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

这又是第一个线索。

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

这是因为之前的问题。
