This UT did not achieve the goal we wanted to achieve,
I will add an automated tool that developers can use to automatically format it, just like:

spark/core/src/test/scala/org/apache/spark/SparkThrowableSuite.scala

Lines 46 to 57 in 7dec5eb

	/* Used to regenerate the error class file. Run:
	{{{
	SPARK_GENERATE_GOLDEN_FILES=1 build/sbt \
	"core/testOnly *SparkThrowableSuite -- -t \"Error classes are correctly formatted\""
	}}}
	To regenerate the error class document. Run:
	{{{
	SPARK_GENERATE_GOLDEN_FILES=1 build/sbt \
	"core/testOnly *SparkThrowableSuite -- -t \"Error classes match with document\""
	}}}
	*/
