testing_plugins:testing-plugins-fixtures	testing_plugins	testing-plugins-fixtures	Using pytest fixtures	Pytest fixtures can be used to create initial testable objects which can then be used by multiple tests. A common pattern for Datasette plugins is to create a fixture which sets up a temporary test database and wraps it in a Datasette instance. Here's an example that uses the sqlite-utils library to populate a temporary test database. It also sets the title of that table using a simulated metadata.json configuration: from datasette.app import Datasette import pytest import sqlite_utils @pytest.fixture(scope="session") def datasette(tmp_path_factory): db_directory = tmp_path_factory.mktemp("dbs") db_path = db_directory / "test.db" db = sqlite_utils.Database(db_path) db["dogs"].insert_all( [ {"id": 1, "name": "Cleo", "age": 5}, {"id": 2, "name": "Pancakes", "age": 4}, ], pk="id", ) datasette = Datasette( [db_path], metadata={ "databases": { "test": { "tables": { "dogs": {"title": "Some dogs"} } } } }, ) return datasette @pytest.mark.asyncio async def test_example_table_json(datasette): response = await datasette.client.get( "/test/dogs.json?_shape=array" ) assert response.status_code == 200 assert response.json() == [ {"id": 1, "name": "Cleo", "age": 5}, {"id": 2, "name": "Pancakes", "age": 4}, ] @pytest.mark.asyncio async def test_example_table_html(datasette): response = await datasette.client.get("/test/dogs") assert ">Some dogs</h1>" in response.text Here the datasette() function defines the fixture, which is than automatically passed to the two test functions based on pytest automatically matching their datasette function parameters. The @pytest.fixture(scope="session") line here ensures the fixture is reused for the full pytest execution session.
