第二步， 根據(jù)每個(gè)testcase建立TestCase類的實(shí)例：
class TestCase:
def __init__(self， _testcase):
self.name=_testcase.attrib['name']
_list=[]
self.actions=[]
try:
_list=_testcase.getchildren()
except Exception，msg:
print msg
self._executor=_testcase.find('Executable').text
self.address=_testcase.find('Address').text
for act in _testcase.findall('Action'):
if act.tag=='Action':
_action=Action(act)
self.actions.append(_action)
def setUp(self):
if 'Chrome'==self._executor:
self.executor=webdriver.Chrome()
elif 'Firefox'==self._executor:
self.executor=webdriver.Firefox()
else:
self.executor=webdriver.Ie()
self.executor.get(self.address)
def tearDown(self):
self.executor.quit()
def execute(self):
logging.debug("Start to execute the testcase:%s" % self.name)
print "TestCaseName:%s" % self.name
try:
self.setUp()
for action in self.actions:
action.execute(self.executor);
self.tearDown()
Assert.AssertPass("TestCase:%s " % self.name)
except Exception as error:
print error
self.tearDown()
Assert.AssertFail("TestCase:%s " % self.name)
第三步，根據(jù)xml里定義的type來(lái)觸發(fā)動(dòng)作，我簡(jiǎn)單的列了下：
def execute(self，executor):
_type=self._actions['Type']
self.getBy(self._actions)
try:
if self.by!=None:
ele=self.findElement(executor)
Assert.AssertIsNotNull(ele，" ".join("Find element by %s:%s" % (str(self.by)，self.by_value)))
if _type=='Input':
ele.send_keys(self._actions['Content'])
time.sleep(3)
elif _type=='Click':
ele.click()
elif _type=='Scroll':
webOperate.page_scroll(executor)
elif _type=='Back':
webOperate.goBack(executor)
else:
print " "，
Assert.AssertFail(self._name)
print "No such action:%s" % _type
if self._expected is not None:
Assert.AssertIsTrue(self.isExpected(executor)，" ".join("Find element by %s:%s" % (str(self.by)，self.by_value)))
print " "，
Assert.AssertPass(self._name)
except AssertionError:
print " "，
Assert.AssertFail(self._name)
raise AssertionError(self._name +" execute failed")
看一個(gè)運(yùn)行的截圖
代碼比較簡(jiǎn)單，原理也很清晰，是解析XML文件，然后調(diào)用相應(yīng)的selenium代碼，但是如果我們?cè)偕钊氲南胂耄诮馕鲞@些XML的時(shí)候，是不是可以以更友好的方式來(lái)展示生成的代碼呢，甚或者以UI的方式，一條條展示。然后再提供可編輯功能？甚或者再提供錄制的方式來(lái)自動(dòng)生成這些XML文件，再解析成代碼，這不是一個(gè)強(qiáng)大的自動(dòng)化測(cè)試工具？？
