Parameters

  • expected
    Type: ICollection

    The first collection to compare. This contains the elements the unit test expects.

  • 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

An element was found in one of the collections but not the other.

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.
