randoop.condition.specification.Postcondition

public class Postcondition
extends SpecificationClause

A Postcondition is a specification clause of a contract on the outcome of the invocation of an operation. The specification consists of a Guard and a Property. For an invocation of the operation, if the Guard evaluates to true, then the Property must also be true.

The JSON serialization of this class is used to read the specifications for an operation given using the --specifications command-line option. The JSON should include a JSON object labeled by the name of each field of this class, as in

   {
     "property": {
        "conditionText":  "result >= 0",
        "description": "received value is non-negative"
      },
     "description": "returns non-negative received value",
     "guard": {
        "conditionText": "true",
        "description": ""
      }
   }
 

See the classes Guard and Property for details on specifying those objects.
