Load testing a GraphQL API using Artillery

Load Testing a GraphQL API using Artillery

This example shows you how to load test on a GraphQL API using Artillery.

Running the GraphQL server

This example runs a GraphQL server using Apollo Server and Prisma for data persistence. Prisma is configured to use PostgreSQL.

First, install the server dependencies:

npm install

Next, configure your PostgreSQL server connection string by setting the DATABASE_URL environment variable (either on the server or through the .env file). With the database created and configured, set up the required database tables by running the Prisma database migrations:

npx prisma migrate dev

After installing the dependencies and setting up the database, start the GraphQL server:

node app.js

This command will start the GraphQL API server listening at http://localhost:4000/. Once the server is up and running, you can explore the server using the Apollo Sandbox.

Running Artillery tests

This repo contains two test scripts ([tests/performance/graphql.yml] and [tests/performance/users.yml]) which runs a few end-to-end flows against the GraphQL server. Once the GraphQL server is up and running, execute the test scripts:

npm run test:graphql
npm run test:users
