Finding the Breaking Point: Data-Driven Load Testing with JMeter & Docker

Source: Dev.to

Introduction

As a QA engineer, I know how hard it is to create real, data‑driven performance tests. Managing dynamic test data and finding the actual breaking point of an application can be a real headache.

I built a complete test environment to solve this problem and wrote a 3‑part series about the solution. The final architectural deep‑dive is published on ITNEXT.

What You’ll Learn

• Setting up a local target app with Docker and simulating 1,000 concurrent users.
• Dynamically using CSV files in JMeter for data‑driven testing.
• Running heavy tests without the GUI (CLI mode) to save system resources and obtain accurate results.
