-------------------------------
Summary: 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
Fix For: 1.10.0
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.
