Consider this Django test case snippet:
from django.test import TestCase

class SimpleTest(TestCase):
    def test_addition(self):
        self.assertEqual(2 + 2, 4)

What will happen when you run this test?
AThe test will pass because 2 + 2 equals 4
BThe test will fail because 2 + 2 is not 4
CThe test will raise a syntax error
DThe test will be skipped automatically
Step-by-Step Solution
Solution:
  1. Step 1: Understand the test logic

    The test checks if 2 + 2 equals 4 using assertEqual.
  2. Step 2: Evaluate the assertion

    Since 2 + 2 is indeed 4, the assertion passes and the test succeeds.
  3. Final Answer:

    The test will pass because 2 + 2 equals 4 -> Option A
  4. Quick Check:

    2 + 2 = 4 test passes [OK]
Quick Trick: assertEqual checks if values match exactly [OK]
