Performance testing (PT) is essentially a testing practice to determine how a system performs by observing its stability and responsiveness. The simplest form of PT is load testing. Load testing is performed by applying a simulated load to a system and measuring the overall impact on the system. A GraphQL server is running as a resolver for GraphQL queries and mutations which usually connects to some microservices and databases. To apply a load test on it, we can use Apache JMeter to simulate a user flow from the front-end side of an app with a number of concurrent requests.
