Demo GraphQL for karate tests

Sample GraphQL apps about football players belongs to a team and a team belongs to a league.

You can toy around and testing the queries and mutation using karate test project provided in folder qa. This sample application is intended to make people more aware about how powerful yet easy to use karate is. Credit to Snipcart for the tutorial provided.

Sample query:

query{
  players{
    id
    first_name
    last_name
    team{
      id
      name
      is_league_winner
      current_competitions
      league{
        id
        name
        continent
      }
    }
  }
}

Query returns:
