--------------------------------------------

I'm trying to [reproduce this test error](https://github.com/apache/spark/blob/227cd8bb8f5d8d442f225057db39591b3c630f46/python/pyspark/sql/tests/connect/test_connect_column.py#L816), but I don't think I'm actually running the test. I get no output when I place a print statement. There is also no expected error.

how to reproduce:

```
~/work/spark master* ⇣
myenv ❯ python/run-tests --testnames pyspark.sql.tests.connect
✦ ~/work/spark master* ⇣ 20s
myenv ❯ bash tests.sh
Running PySpark tests. Output is in /home/g/work/spark/python/unit-tests.log
