Pytest fixtures are a powerful feature for setup and teardown in test cases. They allow you to share setup logic across multiple tests, making your code cleaner and more efficient. Here's how to use them effectively:
📌 What Are Fixtures?
Fixtures are functions that run before or after tests. They can:
- Provide data for tests
- Set up environment (e.g., databases, files)
- Clean up resources after tests
Example:
import pytest
@pytest.fixture
def sample_data():
return {"key": "value"}
def test_example(sample_data):
assert sample_data["key"] == "value"
🚀 Key Features
- Scope: Control how often a fixture runs (
function
,class
,module
,session
) - Params: Pass multiple values to a fixture
- Autouse: Automatically use a fixture without declaring it in test functions
