Assertequals
Function prototype 1: assertequals ([String message],expected,actual)
Parameter description:
The message is optional and, if provided, will be reported when an error occurs.
expected are expected and are typically user-specified content.
actual is the actual value returned by the code being tested.
function prototype 2:assertequals ([String message],expected,actual,tolerance)
Parameter description:
The message is optional and, if provided, will be reported when an error occurs.
Expected are expected and are typically user-specified content.
Actual is the actual value returned by the code being tested.
Tolerance is the error parameter, and the two floating-point numbers participating in the comparison are considered
Equal.

Example:

#定义被测方法, file name is wait_test.py

def add (A, B):
    Return a+b

Def Cheng (A, B):
    Return a*b
---------------------------------

Import UnitTest
From wait_test Import *

Class MyTest (UnitTest. TestCase):

def test_add (self):
#断言
        Self.assertequal (8,add (3,5), ' error ')

    def Test_cheng (self):
        Self.assertequal (15,cheng (3,5), ' error ')


if __name__ = = ' __main__ ':
Unittest.main ()
