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 Valkey integration should inherit the relevant mixins to avoid maintaining duplicate test code.

What needs to be done

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

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

Note: The existing Valkey async tests use non-standard naming (e.g. test_async_write_and_count_documents instead of test_write_documents_async). When inheriting the mixins, ensure the mixin tests don't overlap in intent with the remaining store-specific tests.

Tests that can be removed (covered by mixins)

• test_async_write_and_count_documents → covered by CountDocumentsAsyncTest + WriteDocumentsAsyncTest
• test_async_write_and_delete_documents → covered by DeleteDocumentsAsyncTest
• test_async_delete_all_documents → covered by DeleteAllAsyncTest
• test_async_delete_all_documents_empty_store → covered by DeleteAllAsyncTest
• test_delete_by_filter_async
• test_update_by_filter_async
• test_count_documents_by_filter_async
• test_count_unique_metadata_by_filter_async
• test_get_metadata_fields_info_async
• test_get_metadata_field_min_max_async
• test_get_metadata_field_unique_values_async

Tests to keep (Valkey-specific)

• test_async_write_exceed_batch_size
• test_async_write_exact_batch_size
• test_async_write_multiple_full_batches
• test_async_overwrite_documents
• test_async_write_large_batch_performance
• test_async_search_by_embedding_no_limit
• test_async_search_by_embedding_with_limit
• test_async_search_by_embedding_with_category_filter
• test_async_search_by_embedding_with_numeric_filter
• test_async_search_by_embedding_with_or_filter
• test_async_search_by_embedding_with_in_filter
• test_async_similarity_scores_are_set_correctly
• test_async_filter_by_meta_score
• test_async_search_with_meta_score_filter
• test_get_metadata_field_min_max_empty_store_async (Valkey-specific empty-store edge case)
• test_get_metadata_field_unique_values_with_search_term_async (Valkey-specific search term behaviour)

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 Valkey-specific tests are preserved
• The full test suite passes
