Your task

  1. 1POST BASE_URL + "/graphql" with query "query ($id: ID!) { user(id: $id) { id name email } }" and variables { "id": 3 }.
  2. 2Assert 200 with no errors.
  3. 3Assert data.user.name === "Grace Hopper" and email === "grace@acme.test".

Acceptance criteria

  • POST /graphql returns 200
  • Variables are sent
  • At least 3 assertions pass
