We reply on passthrough test suites for transactions test coverage. There are only 3 targeted test suites for large transactions:

• core_txns_multi_oplog_entries
• replica_sets_multi_oplog_txns
• replica_sets_multi_oplog_txns_jscore_passthrough

We need a build variant to leverage the passthrough test coverage of transactions. The tests should set the maxNumberOfTransactionOperationsInSingleOplogEntry to 1.

The new build variant should include the following test suites since they runs at least one test file that includes "startTransaction".

• auth
• auth_audit
• causally_consistent_jscore_txns_passthrough
• change_streams
• change_streams_whole_cluster_passthrough
• change_streams_whole_db_passthrough
• concurrency_replication
• concurrency_replication_ubsan
• concurrency_sharded_replication
• concurrency_sharded_replication_with_balancer
• concurrency_sharded_with_stepdowns
• concurrency_sharded_with_stepdowns_and_balancer
• core_txns
• core_txns_multi_oplog_entries
• logical_session_cache_replication_100ms_refresh_jscore_passthrough
• logical_session_cache_replication_10sec_refresh_jscore_passthrough
• logical_session_cache_replication_1sec_refresh_jscore_passthrough
• logical_session_cache_replication_default_refresh_jscore_passthrough
• multiversion
• multiversion_auth
• no_passthrough
• replica_sets
• replica_sets_auth
• replica_sets_ese
• replica_sets_ese_gcm
• replica_sets_initsync_jscore_passthrough
• replica_sets_initsync_static_jscore_passthrough
• replica_sets_jscore_passthrough
• replica_sets_kill_secondaries_jscore_passthrough
• replica_sets_multi_oplog_txns
• replica_sets_multi_oplog_txns_jscore_passthrough
• replica_sets_multi_stmt_txn_jscore_passthrough
• replica_sets_multi_stmt_txn_kill_primary_jscore_passthrough
• replica_sets_multi_stmt_txn_stepdown_jscore_passthrough
• replica_sets_multi_stmt_txn_terminate_primary_jscore_passthrough
• sharded_causally_consistent_jscore_txns_passthrough
• sharded_collections_causally_consistent_jscore_txns_passthrough
• sharded_jscore_txns
• sharded_jscore_txns_sharded_collections
• sharded_multi_stmt_txn_jscore_passthrough
• sharding
• sharding_auth
• sharding_auth_audit
• sharding_continuous_config_stepdown
• sharding_ese
• sharding_ese_gcm
• sharding_misc

The build variant should also include the following ones, since resmoke -f doesn't work well with JS overrides. These test suites include "txn" in their names.

• concurrency_replication_multi_stmt_txn
• concurrency_replication_multi_stmt_txn_ubsan
• concurrency_sharded_local_read_write_multi_stmt_txn
• concurrency_sharded_local_read_write_multi_stmt_txn_with_balancer
• concurrency_sharded_multi_stmt_txn
• concurrency_sharded_multi_stmt_txn_with_balancer
• concurrency_sharded_multi_stmt_txn_with_stepdowns
• multi_shard_local_read_write_multi_stmt_txn_jscore_passthrough
• multi_shard_multi_stmt_txn_jscore_passthrough
• multi_shard_multi_stmt_txn_kill_primary_jscore_passthrough
• multi_shard_multi_stmt_txn_stepdown_primary_jscore_passthrough
• multi_stmt_txn_jscore_passthrough_with_migration
