In the same result case, I'm worried that we cannot easily understand which
SQL configs cause failures?
IMHO `withSQLConf` has the same issue, too;
```
Seq(true, false).foreach { flag =>
withSQLConf("spark.sql.anyFlag" -> flag.toString) {
...
}
}
```
In this test case (common patterns?), we cannot understand which case (true
or false) causes the failure at first glance. For example, can we use
`withClue` to solve this?
