Review comment:
       This is how `FileBasedDataSourceTest.readFile` is defined:
   
   ```scala
     protected def readFile(path: String, testVectorized: Boolean = true)
         (f: DataFrame => Unit): Unit = {
       withSQLConf(vectorizedReaderEnabledKey -> "false") {
         f(spark.read.format(dataSourceName).load(path.toString))
       }
       if (testVectorized) {
         withSQLConf(vectorizedReaderEnabledKey -> "true") {
           f(spark.read.format(dataSourceName).load(path.toString))
         }
       }
     }
   ```
   so to me it tests both paths. Did I miss anything?
