Some time ago I was working on a GraphQL project that includes activities and each activity can have some comments with the info of the user that created the comment. The first thing that you might think is that it is a problem of query n + 1 , and yes; it is! I decided to implement dataloaders but for some reason, there was an error on the implementation, so it wasn’t caching the query and the result was a lot of request to the database. After finding that issue I implemented it on the right way reducing the queries to the database from 46 to 6. That’s why I decided to create an open source tool that will help me create queries and make load tests just passing my GraphQL schema. How it works: can be used on two ways for the moment; the first one is using .artillery() with a setup, or the second one is .createQuery() that'll create the queries, so you can use with your favorite load tester. easygraphql-load-tester artillery How to use it? Import package. easygraphql-load-tester Read the schema. Initialize the tester, and pass the schema as the first argument. If there are multiples schemas pass an array with the schemas an argument. The second argument are the arguments on the queries, if there are some of them. only : If an argument is an array it should be passed as an string, e.g: '["name", "name 2"]' Note One schema file 'use strict' const EasyGraphQLTester = require('easygraphql-load-tester') const fs = require('fs') const path = require('path') const userSchema = fs.readFileSync(path.join(__dirname, 'user.gql'), 'utf8') const loadTester = new EasyGraphQLLoadTester(userSchema) Multiples schemas files 'use strict' const EasyGraphQLTester = require('easygraphql-load-tester') const fs = require('fs') const path = require('path') const userSchema = fs.readFileSync(path.join(__dirname, 'user.gql'), 'utf8') const familySchema = fs.readFileSync(path.join(__dirname, 'family.gql'), 'utf8') const loadTester = new EasyGraphQLLoadTester([userSchema, familySchema]) Artillery To use with , you must have it installed, in case you don’t have it just run: artillery $ npm install artillery -g index.js You should configure your index.js file: 'use strict' const EasyGraphQLTester = require('easygraphql-load-tester') const fs = require('fs') const path = require('path') const userSchema = fs.readFileSync(path.join(__dirname, 'schema', 'user.gql'), 'utf8') const familySchema = fs.readFileSync(path.join(__dirname, 'schema', 'family.gql'), 'utf8') const args = { getMeByTestResult: { result: 4 }, search: { id: '1' } } const loadTester = new EasyGraphQLLoadTester([userSchema, familySchema], args) const testCases = loadTester.artillery() module.exports = { testCases } artillery.yml The artillery file should have this minimum configuration, you can add yours in case it is needed: config: target: "http://localhost:5000/" phases: - duration: 5 arrivalRate: 1 processor: "./index.js" scenarios: - name: "GraphQL Query load test" flow: - function: "testCases" - loop: - post: url: "/" json: query: "{{ $loopElement.query }}" - log: "----------------------------------" - log: "Query: {{ $loopElement.name }}" over: cases In this case the server is running on http://localhost:5000/ How to run it To run you load test, just run: $ artillery run artillery.yml Result The result is going to be something like this if you apply the basic configuration All virtual users finished Summary report @ 15:03:05(-0500) 2018-11-17 Scenarios launched: 5 Scenarios completed: 5 Requests completed: 40 RPS sent: 8.95 Request latency: min: 1.2 max: 13 median: 2 p95: 6 p99: 13 Scenario counts: GraphQL Query load test: 5 (100%) Codes: 200: 40 load testing one of the queries created if the argument is an array it should be passed as a comment like on the example '["test", “test2”]'.
