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.

Exceptions

Exception Condition
AssertFailedException

expected is equal to actual.

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.
