脑洞大开：CMap 一种 UI 自动化开发模式 - 51Testing软件测试论坛

CMap=CtrlMap控件地图

意图：①抽象控件：将UI自动化开发中的“控件逻辑”与“控件信息”进行隔离 ②自动回归：“控件信息”有变化时可快速的识别出来进行适配。
主要解决：①简化“控件逻辑” ②降低由“控件信息”变化时引起的适配成本。
如何解决：①控件抽象化：例如在WEB自动化中，将"text_field/radio/checkbox/select_list"这些抽象为一种控件，
那么假如有20个页面、平均每个页面10个控件，原本需要写20*10个控件逻辑的，用CMap模式后能简化为20*1个控件逻辑。

②地图化：例如有一个控件的对象名为"AccoCapac.Line_FastEdt_Name"，可以知道它的跳转路径为"AccoCapac->AccoCapac.Line->AccoCapac.Line_FastEdt"

应用实例1-抽象控件（以TesterHome的登录页面为例，先贴出部分关键代码）：

from Selenium2Library import Selenium2Libraryclass CMap(object): """ Singleton_Pattern extend Selenium2Library """ ...# end classclass Signin(object): URL = CMap('https://testerhome.com/account/sign_in', CMap.NONE) Commit = CMap('xpath=//input[@name="commit"]', CMap.BUTTON) Remember = CMap('xpath=//input[@id="user_remember_me"]', CMap.CHECKBOX) User = CMap('xpath=//input[@id="user_login"]', CMap.TEXT_FIELD) Pwd = CMap('xpath=//input[@id="user_password"]', CMap.TEXT_FIELD) FLAG = Commit # a special Ctrl<wait_until_element_is_visible> @staticmethod def GOTO_(): Signin.URL.go_to()# end classSignin.URL.open_browser(browser='firefox') # create browserObj<Singleton_Pattern>, and open#Signin.GOTO_()Signin.FLAG.wait_until_element_is_visible()mysets = {'User': '123', 'Pwd': '456', 'Remember': True}for ictrl, ivalue in mysets.items(): print(' ictrl=%r ivalue=%r' % (ictrl, ivalue)) getattr(Signin, ictrl).Set(ivalue) ifact = getattr(Signin, ictrl).Get() print(' ictrl.Get()=%r' % ifact) assert ifact == ivalue, "ifact==%r, but=%r" % (ivalue, ifact)

应用实例2-自动回归（下图是之前一个项目中，全自动生成的“控件信息”回归代码）：

[color=rgb(0, 105, 214) !important]

class CMap(object):
""" Singleton_Pattern extend Selenium2Library """
B = None # browserObj<Singleton_Pattern>
def __init__(self, locator, ctrlCls, **kw):
if CMap.B is None:
CMap.B = Selenium2Library(**kw)
self._locator = locator
self._ctrlCls = ctrlCls
def __getattr__(self, attr):
return _CMapHelper_BrowserDo(method=attr, arg0=self._locator)
# Abstract_Methods
def Set(self, value=None):
self._ctrlCls(opt='Set', locator=self._locator, value=value)
def Get(self, value=None):
return self._ctrlCls(opt='Get', locator=self._locator)
# Abstract_Methods's real_method
@staticmethod
def __TEXT_FIELD__(opt, locator, value=None):
if opt == 'Set':
CMap.B.input_text(locator, value)
elif opt == 'Get':
return CMap.B.get_webelement(locator).get_attribute('value')
@staticmethod
def __BUTTON__(opt, locator, value=None):
if opt == 'Set':
CMap.B.click_element(locator)
elif opt == 'Get':
return CMap.B.get_text(locator)
@staticmethod
def __CHECKBOX__(opt, locator, value=None):
""" value==is_selected() # True/False """
elementGet = CMap.B.get_webelement(locator)
if opt == 'Set':
return elementGet.click() if elementGet.is_selected()!=value else None
elif opt == 'Get':
return elementGet.is_selected()
# ctrlCls
TEXT_FIELD = __TEXT_FIELD__
BUTTON = __BUTTON__
CHECKBOX = __CHECKBOX__
NONE = None
# end class
class _CMapHelper_BrowserDo(object):
def __init__(self, method, arg0):
self.method = method
self.arg0 = arg0
def __call__(self, *args, **kw):
return getattr(CMap.B, self.method)(self.arg0, *args, **kw)
# end class
