instead of keeping adding test cases in SQLQuerySuite, shall we create a dedicate test suite for file based data source now?

+1. That's a best idea. I'll update like that.

withTempPath { path =>
val dir = path.getCanonicalPath

// scalastyle:off nonascii
val df = Seq("a").toDF("한글")
// scalastyle:on nonascii

df.write.format(format).option("header", "true").save(dir)
val answerDf = spark.read.format(format).option("header", "true").load(dir)

assert(df.schema === answerDf.schema)
checkAnswer(df, answerDf)
}
}
}
}
