Parameters

  • expected
    Type: ICollection

    The first collection to compare. This contains the elements the unit test expects to be different from the actual collection.

  • actual
    Type: ICollection

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

  • 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

Exception Condition
AssertFailedException

The two collections contain the same elements, including the same number of duplicate occurrences of each element.

Remarks

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