Django - Testing Django Applications

Identify the error in this Django model test code:

class UserProfile(models.Model):
    age = models.IntegerField()

class UserProfileTest(TestCase):
    def test_age_positive(self):
        profile = UserProfile(age=-5)
        self.assertTrue(profile.age > 0)

AThe model field type is incorrect for age

BThe test method name does not start with 'test_'

CThe test will fail because age is negative but no validation is done

DThe test should use assertFalse instead of assertTrue

Step-by-Step Solution

Solution:

Step 1: Review the test logic
The test creates a UserProfile with age -5 and asserts age > 0, which is false.
Step 2: Identify why the test fails
There is no validation preventing negative age, so the test fails as expected.
Final Answer:
The test will fail because age is negative but no validation is done -> Option C
Quick Check:
Negative age without validation causes test failure [OK]

Quick Trick: Check test logic matches model validation to avoid failure [OK]

Common Mistakes:

MISTAKES

Assuming test method name is wrong
Thinking IntegerField rejects negatives by default
Confusing assertTrue with assertFalse usage
