Django - Testing Django Applications

Identify the error in this test code:

class Car(models.Model):
    model = models.CharField(max_length=50)

class CarTest(TestCase):
    def test_car_creation(self):
        car = Car(model='Tesla')
        self.assertEqual(car.model, 'Tesla')

ATest method name does not start with 'test_'

BCar object is not saved before assertion

CModel field is missing max_length

DTestCase class is not imported

Step-by-Step Solution

Solution:

Step 1: Check object creation and saving
The Car object is created but not saved to the test database.
Step 2: Understand assertion context
Even without saving, accessing car.model works, so test passes but does not test DB save.
Step 3: Identify best practice
To fully test model creation, car.save() should be called before assertion.
Final Answer:
Car object is not saved before assertion -> Option B
Quick Check:
Save object to test DB before assertions [OK]

Quick Trick: Call save() to test database persistence [OK]

Common Mistakes:

MISTAKES

Assuming object is saved automatically on creation
Ignoring save() before assertions
