How can you organize the automatic launch of ready data or settings before running tests?

Automatic startup of prepared data or settings before tests is usually organized using special hooks or initialization methods in test frameworks.

For example, in Python with pytest, you can use fixtures with the parameter autouse=True, which are executed before each test:

import pytest

@pytest.fixture(autouse=True)
def setup_data():
    # prepare data or settings
    print("Initializing data before test")
    yield
    # cleanup after test

In Java with JUnit, annotations @Before or @BeforeEach are used for methods that run before tests.

Thus, you can centrally prepare the environment, load necessary data, or perform setup so that tests are isolated and reproducible.
