Python - AttributeError: 'OnDemand' object has no attribute 'calc'

Question

Something is really happening and i couldnt resolve for a day almost

Examples are below: Trying a simple method calling from one class to another class to figure out the problem as i have experienced the notorious problem this morning as well... so have tried a simple method calling checks... Two Class: HomePageAlone OnDemand

HomePageAlone - defined a test "def test_E_Access(self):" calls method in OnDemand i got the below error.

Code as follows:

HomePageAlone

from sikuli import *
from OnDemand import *
import OnDemand

class homePage(unittest.TestCase):

 def setUp(self):
  print("Test")   


 def test_E_Access(self):
  callMethod = OnDemand()
  callMethod.calc() # Line#15


suite = unittest.TestSuite()
suite.addTest(homePage('test_E_Access'))
unittest.TextTestRunner(verbosity=2).run(suite)

OnDemand

from sikuli import *

class OnDemand(object):

    def setUp(self):
        print("setup")


    def calc(self):
        print ("This is calling")

Log Message

ERROR: test_E_Access (main.homePage)

Traceback (most recent call last): File "C:\DOCUME~1\Senthil.S\LOCALS~1\Temp\sikuli-6018543662740221054.py", line 15, in test_E_Access callMethod.calc(self) # Line#15 AttributeError: 'OnDemand' object has no attribute 'calc'

Ran 1 test in 0.016s

Another Try : i tried to use as the below snippet as your suggested - it always throws AttributeError: 'OnDemandPopular' object has no attribute 'calc'

import OnDemandPopular ondemand = OnDemandPopular.OnDemandPopular() ondemand.calc()

You should import OnDemand class from OnDemand module;

from OnDemand import OnDemand

HomePageAlone

import unittest
from OnDemand import OnDemand

class homePage(unittest.TestCase):

 def setUp(self):
  print("Test")   

 def test_E_Access(self):
  callMethod = OnDemand()
  callMethod.calc() # Line#15


suite = unittest.TestSuite()
suite.addTest(homePage('test_E_Access'))
unittest.TextTestRunner(verbosity=2).run(suite)

OnDemand

class OnDemand(object):

    def setUp(self):
        print("setup")

    def calc(self):
        print ("This is calling")

The Output is ;

This is calling
test_E_Access (HomePageAlone.homePage) ... ok

Test
This is calling
----------------------------------------------------------------------

Ran 1 test in 0.000s

OK
Test
This is calling

What is the difference between Module and class? Class has methods and trying to access a method on the class by importing and defining an object. Do you mean a module can have multiple classes?? Please help.

In essence; Module includes classes, you must google it!
