Hi all,
I have been playing a bit with SQLImplicits and noticed that it is an
abstract class. I was wondering why is that? It has no constructor.
Because of it being an abstract class it means that adding a test trait
cannot extend it and still be a trait.
Consider the following:
trait MySparkTestTrait extends SQLImplicits {
lazy val spark: SparkSession = SparkSession.builder().getOrCreate()
protected override def _sqlContext: SQLContext = spark.sqlContext
}
This would mean that if I can do something like this:
class MyTestClass extends FunSuite with MySparkTestTrait {
test("SomeTest") {
// use spark implicits without needing to do import
spark.implicits._
}
}
Is there a reason for this being an abstract class?
