trait Sequencing[-S] extends AnyRef

Typeclass that enables for sequencing certain contain syntax in the ScalaTest matchers DSL.

An Sequencing[A] provides access to the "sequenching nature" of type A in such a way that relevant contain matcher syntax can be used with type A. An A can be any type of sequencing—an object that in some way brings together other objects in order. ScalaTest provides implicit implementations for several types out of the box in the Sequencing companion object:

  • scala.collection.GenSeq
  • scala.collection.SortedSet
  • scala.collection.SortedMap
  • Array
  • java.util.List
  • java.util.SortedSet
  • java.util.SortedMap
  • String

The contain syntax enabled by this trait is:

  • result should contain inOrder (1, 2, 3)
  • result should contain inOrderOnly (1, 2, 3)
  • result should contain theSameElementsInOrderAs List(1, 2, 3)

You can enable the contain matcher syntax enabled by Sequencing on your own type U by defining an Sequencing[U] for the type and making it available implicitly.

Abstract Value Members

  1. abstract def containsInOrder(sequence: S, eles: Seq[Any]): Boolean

    Implements contain inOrder syntax for sequences of type S.

    Implements contain inOrder syntax for sequences of type S.

    sequence

    an sequence about which an assertion is being made

    eles

    elements all of which should be contained, in order of appearance in eles, in the passed sequence

    returns

    true if the passed sequence contains all of the passed elements in (iteration) order

  2. abstract def containsInOrderOnly(sequence: S, eles: Seq[Any]): Boolean

    Implements contain inOrderOnly syntax for sequences of type S.

    Implements contain inOrderOnly syntax for sequences of type S.

    sequence

    an sequence about which an assertion is being made

    eles

    the only elements that should be contained, in order of appearence in eles, in the passed sequence

    returns

    true if the passed sequence contains only the passed elements in (iteration) order

  3. abstract def containsTheSameElementsInOrderAs(leftSequence: S, rightSequence: GenTraversable[Any]): Boolean

    Implements contain theSameElementsInOrderAs syntax for sequences of type S.

    Implements contain theSameElementsInOrderAs syntax for sequences of type S.

    leftSequence

    an sequence about which an assertion is being made

    rightSequence

    an sequence that should contain the same elements, in (iterated) order as the passed leftSequence

    returns

    true if the passed leftSequence contains the same elements, in (iterated) order, as the passed rightSequence
