第二步， 根据每个testcase建立TestCase类的实例：
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，根据xml里定义的type来触发动作，我就简单的列了下：
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") |
看一个运行的截图
代码比较简单，原理也很清晰，就是解析XML文件，然后调用相应的selenium代码，但是如果我们再深入的想想，在解析这些XML的时候，是不是可以以更友好的方式来展示生成的代码呢，甚或者以UI的方式，一条条展示。然后再提供可编辑功能？甚或者再提供录制的方式来自动生成这些XML文件，再解析成代码，这不就是一个强大的自动化测试工具？？
