             Summary: Checking `resolved === false` is enough for testcases.
                 Key: SPARK-15462
                 URL: https://issues.apache.org/jira/browse/SPARK-15462
             Project: Spark
          Issue Type: Bug
          Components: SQL, Tests
            Reporter: Dongjoon Hyun


In only `catalyst` module, there exists 7 evaluation test cases on unresolved evaluations. But, in real-world situation, those cases doesn't happen since there occurs exceptions before evaluations.

{code}
scala> sql("select format_number(null, 3)")
res0: org.apache.spark.sql.DataFrame = [format_number(CAST(NULL AS DOUBLE), 3): string]

scala> sql("select format_number(cast(null as NULL), 3)")
org.apache.spark.sql.catalyst.parser.ParseException:
DataType null() is not supported.(line 1, pos 34)
{code}

This PR makes those testcases more realistic.
{code}
-    checkEvaluation(FormatNumber(Literal.create(null, NullType), Literal(3)), null)
+    assert(FormatNumber(Literal.create(null, NullType), Literal(3)).resolved === false)
{code}

Also, this PR also removes redundant `resolved` checking in `FoldablePropagation` optimizer.
