             Summary: Test the error class: CANNOT_CAST_DATATYPE
                 Key: SPARK-38719
                 URL: https://issues.apache.org/jira/browse/SPARK-38719
             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 AMBIGUOUS_FIELD_NAME to QueryCompilationErrorsSuite. The test should cover the exception throw in QueryCompilationErrors:

{code:scala}
  def ambiguousFieldNameError(
      fieldName: Seq[String], numMatches: Int, context: Origin): Throwable = {
    new AnalysisException(
      errorClass = "AMBIGUOUS_FIELD_NAME",
      messageParameters = Array(fieldName.quoted, numMatches.toString),
      origin = context)
  }
{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
