Aggregating[A]provides access to the "aggregating nature" of typeAin such a way that relevantcontainmatcher syntax can be used with typeA. AnAcan be any type of aggregation—an object that in some way aggregates or brings together other objects. ScalaTest provides implicit implementations for several types out of the box in theAggregatingcompanion object:scala.collection.GenTraversableStringArrayjava.util.Collectionjava.util.MapThe
