CSV for JMeter

Generated CSV is ready to use directly as a JMeter CSV Data Set Config:

username,email,password,userId
john_doe,john.doe@example.com,Qm3#xR9!,550e8400-e29b
jane_smith,jane.smith@example.com,Pk7!nL2@,6ba7b810-9dad

JMeter config:

<CSVDataSet>
  <filename>users.csv</filename>
  <variableNames>username,email,password,userId</variableNames>
  <shareMode>shareMode.all</shareMode>
  <recycle>true</recycle>
</CSVDataSet>

CSV for k6

import { SharedArray } from 'k6/data';

const users = new SharedArray('users', function() {
  return papaparse.parse(open('./users.csv'), { header: true }).data;
});

export default function() {
  const user = users[__VU % users.length];
  // use user.email, user.password, etc.
}

CSV for Gatling

val feeder = csv("users.csv").circular

scenario("Login")
  .feed(feeder)
  .exec(http("Login")
    .post("/api/auth/login")
    .body(StringBody("""{"email":"${email}","password":"${password}"}""")))

API (Pro)

The REST API allows programmatic data generation for integration with CI/CD pipelines:

curl -X POST https://dummydatagenpro.co.uk/api/generate \
  -H "X-API-Key: ${DUMMYDATA_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "rows": 5000,
    "format": "csv",
    "columns": [
      {"name": "userId", "type": "uuid"},
      {"name": "email", "type": "email"},
      {"name": "password", "type": "password"},
      {"name": "createdAt", "type": "datetime", "options": {"from": "2024-01-01"}}
    ]
  }'

perf-ecosystem.yml Integration

services:
  dummydatagenpro:
    url: "https://dummydatagenpro.co.uk"
    api_key: "${DUMMYDATA_API_KEY}"

When configured, perf-ci-pipelines templates can include a data generation step before test execution.
