PyTest - Fixtures

Given this pytest code snippet, how many times will setup_db run?

import pytest

@pytest.fixture(scope='class')
def setup_db():
    print('Setup DB')

class TestA:
    def test_1(self, setup_db):
        pass
    def test_2(self, setup_db):
        pass

class TestB:
    def test_3(self, setup_db):
        pass

A1 time

B3 times

C2 times

D4 times

Step-by-Step Solution

Solution:

Step 1: Understand class scope behavior
Fixture with class scope runs once per test class, before any tests in that class.
Step 2: Count test classes using the fixture
There are two test classes: TestA and TestB, each uses setup_db fixture.
Step 3: Calculate total runs
setup_db runs once for TestA and once for TestB, total 2 times.
Final Answer:
2 times -> Option C
Quick Check:
class scope = once per class, 2 classes = 2 runs [OK]

Quick Trick: Class scope runs once per test class [OK]

Common Mistakes:

MISTAKES

Counting runs per test method instead of per class
Confusing class scope with function scope
Ignoring multiple test classes
