Popping up is a bunch of code, is not a bit ignorant!, the following small part to explain:
Class Baidu (UnitTest. TestCase):
Baidu class inherits UnitTest. The TestCase class, which inherits from the TestCase class, is the way to tell the UnitTest module, which is a test case.

def setUp (self):
Self.driver = Webdriver. Firefox ()
Self.base_url = "http://www.baidu.com/"
Setup is used to set the initialization part, and the function in this method is called first before the test case executes. This places the invocation of the browser and the access of the URL into the initialization section.

Self.verificationerrors = []
When the script runs, the wrong information will be printed to this list

Self.accept_next_alert = True
Whether to continue accepting the next warning.

def test_baidu (self):
Driver = Self.driver
Driver.get (Self.base_url + "/")
driver.find_element_by_id ("kw"). Send_keys ("Seleniumwebdriver")
driver.find_element_by_id ("su"). Click ()
Our test script is placed in the Test_baidu, which we are not unfamiliar with, because the script we execute is here

def is_element_present (self, how, what):
Try:self.driver.find_element (By=how, value= what)
Except Nosuchelementexception, E:return False
Return True
The Is_element_present function is used to find out whether a page element exists, try...except .... Exception capture for the Python language.
The Is_element_present function is not very useful here, usually deleted, because it is common to judge whether a page element exists in TestCase.

def is_alert_present (self):
Try:self.driver.switch_to_alert ()
Except Noalertpresentexception, E:return False
Return True
Handling of the exception of the pop-up window

def close_alert_and_get_its_text (self):
Try
Alert = Self.driver.switch_to_alert ()
Alert_text = Alert.text
If Self.accept_next_alert:
Alert.accept ()
Else
Alert.dismiss ()
Return Alert_text
Finally:self.accept_next_alert = True
Close the warning and to get the processing of the text box, if Judgment statement has been used many times, is not unfamiliar; try....finally To Python
Exception handling.

def tearDown (self):
Self.driver.quit ()
Self.assertequal ([], self.verificationerrors)
The TearDown method is called after each test method executes, and this place does all the cleanup work done by the test cases, such as exiting
Browser and so on.

Self.assertequal ([], self.verificationerrors)
This is a difficult point to compare the list obtained by the previous Verificationerrors method, such as a list of verificationerrors
Not empty, the error message in the output list

if __name__ = = "__main__":
Unittest.main ()
The Unitest.main () function is used to test test cases in a class that start with test

In this analysis, we have a preliminary understanding of the UnitTest framework. Run the script because the UnitTest framework was introduced,

So the console outputs information such as the number of executions, the time of the use cases, and whether or not OK.

This article is only a preliminary analysis of the framework of UnitTest, and the details will be discussed in the following chapters, such as Python exception handling mechanism.
