搭建测试环境中出现的问题总结

配置错误

在搭建测试中出现如下代码错误：selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

此时的版本执行需要驱动：geckodriver，解压放到D:\Python27中，然后在路径中会出现图2 的一些文件。最后配置图3 关于geckodriver驱动的路径。

                           

        图1                                                            图2                                                                                                      图3

代码错误

在搭建测试中出现：mon.exceptions.WebDriverException:Message: Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line。

方案一：这时我们需要指定Firefox浏览器程序路径。

binary = FirefoxBinary('D:\\Firefox\\Firefox\\firefox.exe')
driver = webdriver.Firefox(firefox_binary=binary)

注：提示找不到"firefoxBinary"可以通过下面语句导入from selenium.webdriver.firefox.firefox_binary import FirefoxBinary这样就能正常使用了。

方案二：

将firefox的安装路径，直接增加到 python35\Lib\site-packages\selenium\webdriver\firefox目录下的 firefox_binary.py文件中，如下图所示，然后driver = webdriver.Firefox()调用.

安装SetupTools出现问题

出现此错误Python version 2.7 required, which was not found in the registry

新一个register.py 文件，把下面代码贴进去，保存（G盘）

import sys
 
from _winreg import *
 
# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix
 
regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
    installpath, installpath, installpath
)
def RegisterPy():
    try:
        reg = OpenKey(HKEY_CURRENT_USER, regpath)
    except EnvironmentError as e:
        try:
            reg = CreateKey(HKEY_CURRENT_USER, regpath)
            SetValue(reg, installkey, REG_SZ, installpath)
            SetValue(reg, pythonkey, REG_SZ, pythonpath)
            CloseKey(reg)
        except:
            print "*** Unable to register!"
            return
        print "--- Python", version, "is now registered!"
        return
    if (QueryValue(reg, installkey) == installpath and
        QueryValue(reg, pythonkey) == pythonpath):
        CloseKey(reg)
        print "=== Python", version, "is already registered!"
        return
    CloseKey(reg)
    print "*** Unable to register!"
    print "*** You probably have another Python installation!"
 
if __name__ == "__main__":
RegisterPy()

在系统命令中输入以下命令：

当显示“python 2.7 is already registered”，再安装setuptools的时候，就能自动识别出来python2.7了。win7是 64的原因，在安装python（32位）时，如果选择只为当前用户，以上问题是不会出现的，如果选择所有用户，那就用上面的方法解决吧。
