PyTest - Test Organization

This fixture in conftest.py aims to provide a database connection:

import pytest

@pytest.fixture
def db_conn():
    conn = connect_db()
    yield conn
    conn.close()

Tests fail with NameError: name 'connect_db' is not defined. How can you fix this?

AChange <code>yield</code> to <code>return</code> in the fixture

BImport or define the <code>connect_db</code> function before using it in the fixture

CRemove the <code>@pytest.fixture</code> decorator

DRename the fixture to avoid conflicts

Step-by-Step Solution

Solution:

Step 1: Understand the error
NameError means connect_db is not defined or imported.
Step 2: Fix by importing or defining
Ensure connect_db is either imported from the module where it is defined or implemented in conftest.py.
Final Answer:
Import or define the connect_db function before using it in the fixture -> Option B
Quick Check:
Undefined functions must be imported or defined [OK]

Quick Trick: Always import functions used in fixtures [OK]
