| 67 | +## Duplicates to Remove |
| 68 | + |
| 69 | +### From test_batch_operations.py - ALL tests are duplicated: |
| 70 | +- test_logged_batch |
| 71 | +- test_unlogged_batch |
| 72 | +- test_counter_batch |
| 73 | +- test_mixed_batch_types_error |
| 74 | +- test_batch_with_prepared_statements (merged into test_logged_batch) |
| 75 | +- test_batch_consistency_levels |
| 76 | +- test_large_batch_warning |
| 77 | +- test_conditional_batch (concept merged into LWT tests) |
| 78 | +- test_counter_batch_concurrent (merged into test_counter_batch) |
| 79 | +- test_batch_with_custom_timestamp |
| 80 | + |
| 81 | +### From test_lwt_operations.py (Integration) - ALL tests are duplicated: |
| 82 | +- test_insert_if_not_exists_success (merged into test_insert_if_not_exists) |
| 83 | +- test_insert_if_not_exists_conflict (merged into test_insert_if_not_exists) |
| 84 | +- test_update_if_condition_match (merged into test_update_if_condition) |
| 85 | +- test_update_if_condition_no_match (merged into test_update_if_condition) |
| 86 | +- test_delete_if_exists_success (merged into test_delete_if_exists) |
| 87 | +- test_delete_if_exists_not_found (merged into test_delete_if_exists) |
| 88 | +- test_concurrent_inserts_if_not_exists (renamed to test_concurrent_lwt_operations) |
| 89 | +- test_optimistic_locking_pattern |
| 90 | +- test_complex_condition_with_multiple_columns (concept merged into test_update_if_condition) |
| 91 | +- test_prepared_statements_with_lwt (concept integrated throughout) |
| 92 | +- test_lwt_error_handling (replaced by test_lwt_timeout_handling) |
| 93 | + |
| 94 | +### From test_lwt_operations.py (Unit) - Keep unit tests as they test the wrapper logic: |
| 95 | +The unit tests serve a different purpose (testing the AsyncCassandraSession wrapper) and should be kept. |
| 96 | + |
| 97 | +## Recommendation |
| 98 | + |
| 99 | +1. **DELETE** test_batch_operations.py - All functionality is covered in consolidated file |
| 100 | +2. **DELETE** tests/integration/test_lwt_operations.py - All functionality is covered in consolidated file |
| 101 | +3. **KEEP** tests/unit/test_lwt_operations.py - Unit tests serve different purpose (wrapper logic) |
| 102 | + |
| 103 | +The consolidated file provides better organization, more comprehensive testing, and includes additional patterns like test_read_before_write_pattern. |
