| test_read_read_write_read() X-Ref |
| Test correct database handles are used in a read-read-write-read scenario. Test lazy creation of the write handle. return: void |
| test_read_write_write() X-Ref |
| Test correct database handles are used in a read-write-write scenario. return: void |
| test_write_read_read() X-Ref |
| Test correct database handles are used in a write-read-read scenario. return: void |
| test_read_temptable() X-Ref |

| Test readonly handle is not used for reading from excluded tables. return: void |
| test_transaction() X-Ref |
| Test readonly handle is not used during transactions. Test last written time is adjusted post-transaction, so the latency parameter is applied properly. return: void |
