Description

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

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

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

The test must have a check of:

1. the entire error message
2. sqlState if it is defined in the error-classes.json file
3. the error class
