This is equivalent to running the  datasette  command-line tool with the  --pdb  option. \n             Here's what that looks like in a test function: \n             def test_that_opens_the_debugger_or_errors():\n    ds = Datasette([db_path], pdb=True)\n    response = await ds.client.get(\"/\") \n             If you use this pattern you will need to run  pytest  with the  -s  option to avoid capturing stdin/stdout in order to interact with the debugger prompt.", "breadcrumbs": "[\"Testing plugins\"]", "references": "[]"}
