The stand-alone repro confirms the server *does* reject cross-partition batches with `400 BadRequest` — so this is not a server bug. | +| `CosmosTransactionalBatchTest.SaveChanges_transaction_behavior_always_fails_for_multiple_entities_with_triggers` | Same family — expects the client-side `…TriggerAtomicity` check from `CosmosDatabaseWrapper.cs:225-232`; does not fire. | +| `CosmosTransactionalBatchTest.SaveChanges_fails_for_duplicate_key_in_same_partition_prevents_other_inserts_in_same_partition_even_if_staged_before_add` | Expects only the seeded item to remain after a batched insert containing a duplicate id (i.e. atomic rollback). Got 2 items. The stand-alone repro shows that a single transactional batch with a duplicate id *is* rolled back atomically by the Linux emulator — so the EF save is not being sent as one batch in this scenario. | +| `CosmosTransactionalBatchTest.SaveChanges_transaction_behavior_always_fails_for_single_entity_with_trigger_and_entity_without_trigger` | Expects `InvalidOperationException` (`…TriggerAtomicity`); instead the second save throws a `DbUpdateException` wrapping `409 Conflict`.

Looks like bulk grouping behaves differently than the test assumes. | -| `CosmosBulkExecutionTest.AutoTransactionBehaviorAlways_Throws`, `AutoTransactionBehaviorWhenNeeded_Throws` | Expect `InvalidOperationException` from the `BulkExecutionWithTransactionalBatch` warning-as-error path; no exception is thrown. The `BulkFixture` ignores that warning, but these two methods build their own `contextFactory` — yet they still don't throw. | -| `CosmosTransactionalBatchTest.SaveChanges_transaction_behavior_always_fails_for_multiple_partitionkeys` | Expects `CosmosStrings.SaveChangesAutoTransactionBehaviorAlwaysAtomicity` from the *client-side* check in `CosmosDatabaseWrapper.cs:244-249`. The check is unconditional but does not fire. The stand-alone repro confirms the server *does* reject cross-partition batches with `400 BadRequest` — so this is not a server bug. | -| `CosmosTransactionalBatchTest.SaveChanges_transaction_behavior_always_fails_for_multiple_entities_with_triggers` | Same family — expects the client-side `…TriggerAtomicity` check from `CosmosDatabaseWrapper.cs:225-232`; does not fire. | -| `CosmosTransactionalBatchTest.SaveChanges_fails_for_duplicate_key_in_same_partition_prevents_other_inserts_in_same_partition_even_if_staged_before_add` | Expects only the seeded item to remain after a batched insert containing a duplicate id (i.e. atomic rollback). Got 2 items. The stand-alone repro shows that a single transactional batch with a duplicate id *is* rolled back atomically by the Linux emulator — so the EF save is not being sent as one batch in this scenario. | -| `CosmosTransactionalBatchTest.SaveChanges_transaction_behavior_always_fails_for_single_entity_with_trigger_and_entity_without_trigger` | Expects `InvalidOperationException` (`…TriggerAtomicity`); instead the second save throws a `DbUpdateException` wrapping `409 Conflict`. Same root cause as the previous row — client-side atomicity check is not firing, so the request reaches the server. | - -## How the data was collected - -```bash -docker run --rm -d -p 8081:8081 \ - mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator:vnext-preview - -# In the repo -. ./activate.sh -dotnet build test/EFCore.Cosmos.FunctionalTests/EFCore.Cosmos.FunctionalTests.csproj - -export Test__Cosmos__DefaultConnection=https://localhost:8081 -export Test__Cosmos__EmulatorType=linux - -dotnet test test/EFCore.Cosmos.FunctionalTests/EFCore.Cosmos.FunctionalTests.csproj \ - --no-build \ - --filter "FullyQualifiedName~CosmosTransactionalBatchTest|FullyQualifiedName~CosmosBulkExecutionTest|FullyQualifiedName~CosmosBulkConcurrencyTest|FullyQualifiedName=Microsoft.EntityFrameworkCore.EndToEndCosmosTest.Can_add_update_delete_end_to_end" -``` - -The skip attributes `[CosmosCondition(CosmosCondition.IsNotLinuxEmulator)]` were removed -from each of the seven `// .../issues/292` sites for the run; once the data was collected -they were restored so the test suite continues to behave as before in CI.
