Re: Tests not passing in suite but pass individually

Will try to send minimal project by end of the day.

Hopefully I can discover the reason during this exercise.

It looks correct. I'd like a minimal project I could download to reproduce the issue. In putting that together, you might discover the reason for the failure.

Below is the test file & logs.

No matter in which order (using --reverse) I run the suite it fails.

The database backend is postgres. Is that an issue ?

How does the test fail? Please show the entire test file including imports.

Hi Tim,

Below is what am trying to achieve.

class OrcaTestCase(TestCase):

    def test_customer_create_modify_delete(self):

        '''Test customer object create, modify and delete operations in  DB.'''

        # Create.

        CustomerDb.objects.create(c_name='Pnc', c_role='ADFS-Admin',

                                  c_date_created=timezone.now(),

                                  c_date_updated=timezone.now())

        customer_list = CustomerDb.objects.all()

        self.assertEqual(len(customer_list), 1)

        # Modify.

        customer = CustomerDb.objects.get(c_name='Pnc')

        self.assertNotEqual(customer, None)

        setattr(customer, 'c_name', 'Zoo')

        customer.save()

        customer_list = CustomerDb.objects.all()

        self.assertEqual(len(customer_list), 1)

        self.assertEqual(str(customer_list[0]), 'Gap')

        # Delete.

        customer = CustomerDb.objects.get(c_name='foo')

        self.assertNotEqual(customer, None)

        customer.delete()

        customer_list = CustomerDb.objects.all()

        self.assertEqual(len(customer_list), 0)

    def test_create_customer(self):

        '''Handle customer create.'''

        customer_list = CustomerDb.objects.all()

        self.assertEqual(len(customer_list), 1)

test_create_customer runs first, test_customer_create_modify_delete fails at the highlighted line.

It will be easier to help if you can provide a sample project that reproduces the error.

Hi,

Am seeing that test case in suite are failing but passing when ran individually.

I have gone through most of the thread on the internet but did not find any solution.

Below is the snip of what am trying to do.

class A(TestCase):

  def test_a():

   create an obj in db

   retrive obj list from db and check the length of the list (should be 1)

   update same obj in db

   delte same obj in db

 def b():

  create an obj in db and check the length.

When ran in suite test_a fails as the length of the list is 2.

test_b() runs before test_a and leave the object in the database.

From various threads suggested using 'django.test import TestCase' 

instead of 'from django.unittest import TestCase' which am already doing.

Is there anything else i need to do here ?
