@pytest.fixture Explanation

@pytest.fixture is a decorator in pytest used to define reusable test setup functions. It allows tests to use shared resources without redundant code.

Example & Usage

python

Copy code

import pytest @pytest.fixture def sample_data(): return {"name": "John Doe", "age": 30} def test_example(sample_data): assert sample_data["name"] == "John Doe" assert sample_data["age"] == 30

🔹 How it works:

• The function sample_data() is decorated with @pytest.fixture, making it a fixture.
• The test function test_example() receives sample_data as an argument.
• pytest automatically provides the fixture data when running the test.

Why use fixtures?

• Avoids repetitive setup code.
• Ensures clean test environments.
• Can handle resource management (e.g., opening/closing database connections, creating temporary files).
