Assertions
Oneof Assertions

What is This Feature About

  • Asserting one of the many possible values of a field

In Which Scenario This Feature Can Be Used

  • When the API or the Service is not deterministic around a field value wrt all fields, but certain about at least one field
  • Pass the assertions, if a field contains just one value you are trying to assert, but your test is not dependent on other values

Problem Example

e.g. a Service sometimes responds with

  • Run 1 "location" : "San Francisco",

  • Run 2 "location" : "New York",

  • Run 3 "location" : "Seattle",

Solution Example

Then you can assert this way:

"location" : "$ONE.OF:[San Francisco, New York, Seattle]"

Scenario example:

{
    "scenarioName": "Assert that value is one of the items in the array",
    "steps": [
        {
            "name": "match_user_location",
            "url": "/users/octocat",
            "method": "GET",
            "request": {
            },
            "assertions": {
                "status": 200,
                "body": {
                    "location" : "$ONE.OF:[San Francisco, New York, Seattle]"
                }
            }
        }
    ]
}
