Nicolas Lu updated SPARK-60148:
-------------------------------
    Description: 
{{pyspark/traceback_utils.py}} has no dedicated unit tests. It is only 
exercised indirectly through RDD and DataFrame actions 
({{{}core/context.py{}}}, {{{}core/rdd.py{}}}, 
{{{}sql/classic/dataframe.py{}}}), so several branches are never checked 
directly.

This ticket adds {{python/pyspark/tests/test_traceback_utils.py}} and registers 
it in {{{}dev/sparktestsupport/modules.py{}}}. It covers:
 * {{{}first_spark_call(){}}}: empty stack returnsĀ {{{}None{}}}; returns the 
user's file and line for the first Spark frame; only the first Spark frame is 
used; Spark frame at the bottom of the stack.
 * {{{}SCCallSiteSync{}}}: sets and clears the call site; fallback message when 
the call site is unknown; nested usage sets the call site only at the outermost 
level; the call site is cleared when the block raises.

I'm working on this and will open a PR shortly
