Parameters

  • message
    Type: System.String
    A message to display if the assertion fails. This message can be seen in the unit test results.
  • parameters
    Type: array<System.Object[]
    An array of parameters to use when formatting message.

Exceptions

Exception Condition
AssertFailedException

An element in subset is not found in superset or an element in subset is not found in superset in sufficient quantity.

Remarks

One collection is a subset of another collection if every element in the first collection also appears in the second collection. An element that appears in the first collection more than once must appear in the second collection as many times, or more, as it does in the first collection. The second collection may have elements that are not in the first collection, but that is not required.
