GraphQL API Testing

What is GraphQL?

GraphQL vs REST

`graphql

GraphQL — one endpoint, request only what you need

query { launches(limit: 5) { id mission_name launch_success } }

REST — multiple endpoints, get everything

GET /launches

GET /launches/:id

GET /rockets

`

Run Tests

�ash npm install npx playwright install chromium npm test # Run all tests npm run test:launches # Launches only npm run test:rockets # Rockets only npm run test:company # Company only
