`DeleteAllAsyncTest`, `DeleteByFilterAsyncTest`,

[davidsbatista]

NOTES:

• Tests should be written into haystack/testing/document_store_async.py
• Use async def for all test methods
• Decorate each test method with @pytest.mark.asyncio
• Rely on an async-compatible document_store fixture (to be provided by the concrete test class in each integration)
• Use await on all *_async() calls
• Use write_documents_async / count_documents_async in setup steps (not the sync variants), so the full async path is exercised end-to-end
• Open the PR to the async-mixin-tests feature branch

DeleteAllAsyncTest

Mirrors: DeleteAllTest

Test	Description
test_delete_all_documents_async	Write 2 docs, delete all, count is 0; write 1 new doc, count is 1
test_delete_all_documents_empty_store_async	delete_all_documents_async() on empty store doesn't raise, count stays 0
test_delete_all_documents_without_recreate_index_async	Skipped if recreate_index/recreate_collection param not present; else tests False variant
test_delete_all_documents_with_recreate_index_async	Skipped if param not present; else tests True variant, verifies store still works after

Use inspect.signature(document_store.delete_all_documents_async) to detect recreate_index/recreate_collection parameter (same pattern as sync DeleteAllTest._delete_all_supports_recreate).

DeleteByFilterAsyncTest

Mirrors: DeleteByFilterTest

Test	Description
test_delete_by_filter_async	Write 3 docs, delete 2 by category filter, verify 1 remains
test_delete_by_filter_no_matches_async	Filter matching nothing returns 0 deleted, store unchanged
test_delete_by_filter_advanced_filters_async	AND and OR compound filter deletions in sequence

Use inspect.signature(document_store.delete_by_filter_async) to detect optional refresh parameter.
