+# pytest-service
+
+Inspired by [pytest-pg](https://pypi.org/project/pytest-pg/) but with `MongoDB` onboard
+
+### How to use
+
+#### Postgres
+
+```python
+@pytest.fixture(scope="session")
+def pg_14_local() -> Iterator:
+    with pytest_service.PGService("postgres:14.4-alpine").run() as pg:
+        yield pg
+
+
+@pytest.fixture(scope="session", autouse=True)
+def init_env(pg_14_local: pytest_service.PG) -> None:
+    if not pg_14_local:
+        return
+    os.environ["POSTGRES_DBNAME"] = pg_14_local.database
+    os.environ["POSTGRES_USER"] = pg_14_local.user
+    os.environ["POSTGRES_PASSWORD"] = pg_14_local.password
+    os.environ["POSTGRES_HOST"] = pg_14_local.host
+    os.environ["POSTGRES_PORT"] = str(pg_14_local.port)
+
+```
+
+#### MongoDB
+
+```python
+@pytest.fixture(scope="session")
+def mongo_6_local() -> Iterator:
+    with pytest_service.MongoDBService("mongo:6").run() as mongo:
+        yield mongo
+
+
+@pytest.fixture(scope="session", autouse=True)
+def init_env(mongo_6_local: pytest_service.Mongo) -> None:
+    if not mongo_6_local:
+        return
+    os.environ["MONGODB_CONNECTION_STRING"] = mongo_6_local.connection_string
+
+```
