+### `make_volume` fixture
+Create a volume and return its info. Remove it after the test. Returns instance of [`VolumeInfo`](https://databricks-sdk-py.readthedocs.io/en/latest/dbdataclasses/catalog.html#databricks.sdk.service.catalog.VolumeInfo).
+
+Keyword Arguments:
+* `catalog_name` (str): The name of the catalog where the schema and the volume are.
+* `schema_name` (str): The name of the schema where the volume is.
+* `name` (str): The name of the volume.
+* `comment` (str, optional): The comment attached to the volume.
+
+Usage:
+```python
+def test_volume_creation(make_catalog, make_schema, make_volume, make_random):
+    # Create a catalog
+    catalog = make_catalog()
+
+    # Create a schema in the catalog
+    schema = make_schema(catalog_name=catalog.name)
+
+    # Generate a random name for the volume
+    volume_name = f"dummy_vol_{make_random(6).lower()}"
+
+    # Create the volume
+    volume = make_volume(
+        catalog_name=catalog.name,
