Description

Rename fields in response using aliases.

Test Scenario

const query = `
  {
    firstUser: user(id: "1") { name }
    secondUser: user(id: "2") { name }
  }
`;
const { data } = await response.json();
expect(data.firstUser.name).toBeDefined();
expect(data.secondUser.name).toBeDefined();
Endpoint/api/graphql

Testing Tips

  • •Useful for same field with different args
  • •Syntax: alias: fieldName
  • •Prevents field name conflicts
// Playwright API Testing - GraphQL
import { test, expect } from '@playwright/test';


test('GraphQL query', async ({ request }) => {
  const response = await request.post('/api/graphql', {
    data: {
      query: `
        query {
          users {
            id
            name
            email
          }
        }
      `
    }
  });


  expect(response.ok()).toBeTruthy();
  const { data } = await response.json();
  expect(data.users).toBeDefined();
});
