UnitTest Unit Test Framework and assertions

I. Introduction to the UNITTEST Unit testing framework

1. Import UnitTest Module

Import UnitTest

2. Define test class

Class Login (UnitTest. TestCase):

3. Pre-conditions

    def setUp (self):        u' no preconditions can write pass'            

4. Test Case plus assertion

    # The test case must start with Test        print (" execute test Case"'1'# to assert that result is true  

5. Post conditions

    def TearDown (self):        u' no post condition can write pass'            

6. Running the main function

'__main__': Unittest.main ()  

Example:

#Import UnitTest ModuleImportUnitTestClassLogin (unittest. TestCase):DefSetUp (self): U‘‘‘No pre-conditions can write pass‘‘‘Passdef test01 (self):#Test cases must start with testprint ( " execute test Case 01 ") result =  ' 1 '  Self.asserttrue (result) # assert that result is true def  TearDown (self): U No post conditions can be written Passpassif" Span style= "COLOR: #800080" >__name__ = =  ' __main__ ' : Unittest.main ()        

Second, assert

UnitTest Common assertion Methods

1, assertequal (self, first, second,msg=none)

    def test02 (self):# Determine if two parameters are equal to        print (" execute test Case"'1'2' self.assertequal (result1,result2,msg="%s not equal to%s"% (RESULT1,RESULT2))     

2, assertnotequal (self, first, second,msg=none)

    def test03 (self):# Determine if two parameters are unequal        print (" execute test Case"'1'2' self.assertnotequal (result1,result2,msg="%s equals%s"% (RESULT1,RESULT2))     

3, Assertin (self, Member, Container,msg=none)

    def test04 (self):# determine if one parameter contains another parameter        print (" execute test Case"' 1'21 ' self.assertin (result1,result2,msg="%s does not contain%s"% (RESULT2,RESULT1))   

4, Assertnotin (self, member,container, Msg=none)

    def test05 (self):# determine if one parameter does not contain another parameter        print (" execute test Case"'1'2 ' self.assertnotin (result1,result2,msg="%s contains%s"% (RESULT2,RESULT1))   

5. Asserttrue (self, expr, msg=none)

    # Test If a parameter is true        print (" execute test Case"' self.asserttrue ' "%s" is not true 

6. Assertfalse (self, expr, msg=none)

    def test07 (self):# Determines if one parameter does not contain another parameter,        print (" execute test Case"' self.assertfalse "( result,msg="%s is not false"% (result))          

7, Assertisnone (self, obj, msg=none)

    def test08 (self):# determine if one parameter does not contain another parameter        print (" execute test Case") result = None Self.assertisnone (result,msg="%s is not none"% (result))        

8, Assertisnotnone (self, obj,msg=none)

    def test09 (self):# determine if one parameter does not contain another parameter        print (" execute test Case"'123'  Self.assertisnotnone (result,msg="%s is none"% (result))       

Example:

#Import UnitTest ModuleImportUnitTestClassLogin (unittest. TestCase):DefSetUp (self): U‘‘‘No pre-conditions can write pass‘‘‘Print"Start execution")#Passdef test01 (self):#Test cases must start with testPrint"Execute test Case 01") result =‘1‘Self.asserttrue (Result)#Assert that result is not truedef test02 (self):#Determine if two parameters are equalPrint"Execute test Case 02") RESULT1 =‘1‘RESULT2 =‘1‘Self.assertequal (result1,result2,msg="%s is not equal to%s"%(RESULT1,RESULT2))def test03 (self):#Determine if two parameters are not equalPrint"Execute test Case 03") RESULT1 =‘1‘RESULT2 =‘2‘Self.assertnotequal (result1,result2,msg="%s equals%s"%(RESULT1,RESULT2))def test04 (self):#Determine if a parameter contains another parameterPrint"Execute test Case 04") RESULT1 =‘1‘RESULT2 =‘21st‘Self.assertin (result1,result2,msg="%s does not contain%s"%(RESULT2,RESULT1))def test05 (self):#Determine if a parameter does not contain another parameterPrint"Execute test Case 05") RESULT1 =‘1‘RESULT2 =‘2‘Self.assertnotin (result1,result2,msg="%s contains%s"%(RESULT2,RESULT1))def test06 (self):#Test whether a parameter is truePrint"Execute test Case 06") result =‘1‘Self.asserttrue (result,msg="%s is not true"%Resultdef test07 (self):#Determine if a parameter does not contain another parameterPrint"Execute test Case 07") result =‘‘Self.assertfalse (result,msg="%s is not false"%(result))def test08 (self):#Determine if a parameter does not contain another parameterPrint"Execute test Case 08") result =None Self.assertisnone (result,msg="%s is not none"%(result))def test09 (self):#Determine if a parameter does not contain another parameterPrint"Execute test Case 09") result =‘123‘ Self.assertisnotnone (Result,msg= " %s is None "%def TearDown (self): U No post-conditions can be written Passprint ( " end ...  ") # Passif __name__ = =  __main__ ": Unittest.main ()  

Ps:unittest executes the setup, executes the test case test* (the test case is executed in the name order), and finally executes the teardown.
