Rest-Assured unable to validate JSON array response

Question

I'm trying to validate that a JSON array contains a certain value. Using Rest-Assured with a hamcrest matchers import in Java. This is the JSON that I'm validating;

{
    "graph": {
        "groupedResultColumns": [
            "Task_Status",
            "Task_TimeSpent"
        ]
    }
}

After reading about rest assured and hamcrest matchers, this is the code that I am trying at the moment;

{
    SerenityRest.then()
      .body(containsString("groupedResultColumns"))
      .assertThat().body("groupedResultColumns", (hasItems("Task_TimeSpent")));
}

This is the error I'm getting;

JSON path groupedResultColumns doesn't match.
Expected: (a collection containing "Task_TimeSpent")
  Actual: null

Any help or advice is appreciated, Thanks!

Answer 1

You need to specify the json path to the collection. The "groupedResultColumns" is inside "graph" so your path to the body would be graph.groupedResultColumns .

Your code would be something like this:

{
    SerenityRest.then()
      .body(containsString("groupedResultColumns"))
      .assertThat().body("graph.groupedResultColumns", (hasItems("Task_TimeSpent")));
}
