Parameters
- subset

The collection expected to be a subset of superset.
- superset
Type: System.Collections.ICollection
The collection expected to be a superset of subset.

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.
