| /* |
| * This test uses a simple physical plan with a mock-scan that |
| * generates one row. The physical plan also consists of the |
| * trace operator which will dump the records as bytes to the |
| * log file. |
| * |
| * Objective of this test is not only to verify if the injected |
| * trace operator dumps the output to the log file, but also |
| * to read the dumped output and verify if it matches what we expect |
| * it to be. Since our scan produces only one record we expect record count to |
| * be one, expect there are no selection vectors and we know the value of |
| * the record that is dumped (Integer.MIN_VALUE) so we compare it with this |
| * known value. |
