Last Updated :

assertGreater() in Python is an unittest library function that is used in unit testing to check whether the first given value is greater than the second value or not. This function will take three parameters as input and return a boolean value depending upon the assert condition.
This function check that if the first given value is greater than the second value and returns true if it is so, else returns false if the first value is not greater than the second value.
Syntax: assertGreater(first, second, message=None)
Parameters: assertGreater() accept three parameters which are listed below with explanation:
- first: first input value (integer)
- second: second input value (integer)
- message: a string sentence as a message which got displayed when the test case got failed.
Listed below is an example illustrating the positive and negative test case for a given assert function:
Example 1:
Python3
import unittest
class TestStringMethods(unittest.TestCase):
def test_negativeForGreater( self ):
first = 4
second = 5
message = "first value is not greater that second value."
self .assertGreater(first, second, message)
if __name__ = = '__main__' :
unittest.main()
|
Output:
F

Example 2:
Python
import unittest
class TestStringMethods(unittest.TestCase):
def test_positiveForGreater( self ):
first = 4
second = 3
message = "first value is not greater that second value."
self .assertGreater(first, second, message)
if __name__ = = '__main__' :
unittest.main()
