             Summary: Test the error class: CANNOT_CHANGE_DECIMAL_PRECISION
                 Key: SPARK-38720
                 URL: https://issues.apache.org/jira/browse/SPARK-38720
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.4.0
            Reporter: Max Gekk


Add at least one test for the error class *CANNOT_CAST_DATATYPE* to QueryExecutionErrorsSuite. The test should cover the exception throw in QueryExecutionErrors:

{code:scala}
  def cannotCastFromNullTypeError(to: DataType): Throwable = {
    new SparkException(errorClass = "CANNOT_CAST_DATATYPE",
      messageParameters = Array(NullType.typeName, to.typeName), null)
  }
{code}

For example, here is a test for the error class *UNSUPPORTED_FEATURE*: https://github.com/apache/spark/blob/34e3029a43d2a8241f70f2343be8285cb7f231b9/sql/core/src/test/scala/org/apache/spark/sql/errors/QueryCompilationErrorsSuite.scala#L151-L170
