Generally, these system tests should be self-contained. The DAG that will be run references ArangoDB documents and data that aren't created or available as part of the test in a resources/ directory as well as missing SQL files.

I would suggest taking a look at the Postgres provider system tests. Tables are created, inserted into, dropped all within the same test, and all SQL is available so it can be executed straight away as written.

Side note, it looks like the other __init__ files for the other providers are unrelated and not needed.

Suggested change

	:start-after: [START howto_aql_operator_template_file_arangodb]
	:dedent: 4
	:start-after: [START howto_aql_operator_template_file_arangodb]

Now that the START/END markers have been indented in the system test example DAG, this option should be added to the exampleinclude:: directives in the docs so the code snippets are rendered properly.

	tags=['example'],
	schedule_interval='@once',
	tags=['example'],

Looks like this parameter is explicitly needed based on the AIP docs.
