Parameters

• notExpected
  Type: ICollection

  The first collection to compare. This is the collection that the unit test does not expect to match actual.

• actual
  Type: ICollection

  The second collection to compare. This is the collection the unit test produced.

• comparer
  Type: IComparer

  The compare implementation to use when comparing elements of the collection.

• message
  Type: String

  A message to display if the assertion fails. This message can be seen in the unit test results.

• parameters
  Type: array<Object[]

  An array of parameters to use when formatting message.

Exceptions

Remarks

Two collections are equal if they have the same elements in the same order and quantity. Elements are equal if their values are equal, not if they refer to the same object.
