REST API RESPONSE ASSERTIONS

1. Verify a field in response

---

{ "guid": "2c2db3b4-a576-4c19-8249-77fe3ac4338a", "version":10, "data": { "message": "Accepted" } }

response.then().statusCode(200);

response.then().body("guid", startsWith("2c2db3b4"));

response.then().body("data.message", equalTo("Accepted"));
OR response.then().body("message", is("Unauthorized token"));

2. Check for presence of key or if the key is not null

response.then().body("guid", is(notNullValue()));

response.then().body("version", is(greaterThan(9))));

response.then().body("data.any { it.key == 'guid'}", is(true));

3. Dealing with arrays

   { "totalCount": 17, "resultCount": 17, "offset": 0,
   "data": { "brands": [ { "name": ".mobi", "id": 1 }, { "name": "Acer", "id": 2 }, { "name": "Ahong", "id": 3 }, { "name": "Airness", "id": 4

response.then().body("data.brands.size", is(resultcount));

response.then().body("data.brands.flatten().any {it.containsKey('id') }", is(true));

4. Separate assertions

capturedVenueId = response.then().extract().path("data.guid").toString(); Assert.assertEquals(capturedVenueId, name, "does not match ");

similarly assertnotequals, assertNotNull etc
