Use async DocumentStore mixin tests in Qdrant

[davidsbatista]

As part of deepset-ai/haystack#10799, async test mixin classes are being added to haystack.testing.document_store. Once those are in place, the Qdrant integration should inherit the relevant mixins to avoid maintaining duplicate test code.

What needs to be done

In integrations/qdrant/tests/test_document_store_async.py, update the async test class to inherit the appropriate mixin classes:

from haystack.testing.document_store import (
    WriteDocumentsAsyncTest,
    DeleteAllAsyncTest,
    DeleteByFilterAsyncTest,
    UpdateByFilterAsyncTest,
    CountDocumentsByFilterAsyncTest,
    CountUniqueMetadataByFilterAsyncTest,
    GetMetadataFieldsInfoAsyncTest,
    GetMetadataFieldMinMaxAsyncTest,
    GetMetadataFieldUniqueValuesAsyncTest,
)

Note: Check whether Qdrant implements count_documents_async and filter_documents_async — if so, also add CountDocumentsAsyncTest and FilterDocumentsAsyncTest.

Tests that can be removed (covered by mixins)

• test_write_documents_async
• test_delete_all_documents_async_no_index_recreation
• test_delete_all_documents_async_index_recreation
• test_delete_by_filter_async
• test_delete_by_filter_async_no_matches
• test_delete_by_filter_async_advanced_filters
• test_update_by_filter_async
• test_update_by_filter_async_multiple_fields
• test_update_by_filter_async_no_matches
• test_update_by_filter_async_advanced_filters
• test_count_documents_by_filter_async
• test_count_unique_metadata_by_filter_async
• test_count_unique_metadata_by_filter_async_multiple_fields
• test_count_unique_metadata_by_filter_async_with_filter
• test_get_metadata_fields_info_async
• test_get_metadata_field_min_max_async
• test_get_metadata_field_unique_values_async
• test_get_metadata_field_unique_values_async_pagination
• test_get_metadata_field_unique_values_async_with_filter

Tests to keep (Qdrant-specific)

• test_sparse_configuration_async
• test_query_hybrid_async
• test_query_hybrid_with_group_by_async
• test_query_hybrid_fail_without_sparse_embedding_async
• test_query_hybrid_search_batch_failure_async
• test_set_up_collection_with_dimension_mismatch_async
• test_set_up_collection_with_existing_incompatible_collection_async
• test_set_up_collection_use_sparse_embeddings_true_without_named_vectors_async
• test_set_up_collection_use_sparse_embeddings_false_with_named_vectors_async
• test_set_up_collection_with_distance_mismatch_async
• test_update_by_filter_async_preserves_vectors (Qdrant-specific vector preservation)

Acceptance criteria

• The async test class inherits the relevant async mixin classes
• The document_store async fixture is correctly wired up
• All duplicate tests listed above are removed
• All Qdrant-specific tests are preserved
• The full test suite passes
