> Improve Expression validation test
> ----------------------------------
>
> Key: FLINK-13525
> URL: https://issues.apache.org/jira/browse/FLINK-13525
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Planner
> Reporter: Jark Wu
> Priority: Minor
> Labels: stale-minor
>
> Currently, the expression validation tests under
> {{org.apache.flink.table.expressions.validation}} are using following pattern
> to verify an exception should be thrown:
> {code:scala}
> @Test
> def testWrongKeyType(): Unit = {
> testAllApis('f2.at(12), "f2.at(12)", "f2[12]", "FAIL")
> }
> {code}
> However, this only covers the first expression {{'f2.at(12)}} throw the
> expected exception. All the other expression will be ignored. We should
> improve this. And it's nice to test the expected exception message too.
