sample-load-test-apache-jmeter

A sample project to demonstrate load testing a python flask web application with Apache JMeter.

Quick Start

To get started, simply:

1. In your terminal, clone this repository, and run the sample server

    git clone git@github.com:ChrisCarini/sample-load-test-apache-jmeter.git
    cd sample-load-test-apache-jmeter
    source setup.sh
    gunicorn -w 8 -b 127.0.0.1:5000 "webapp:create_app()" --access-logfile -

2. Download Apache JMeter (as of publishing, version 5.4.1 is the latest - this sample assumes you are using that version.)

   • Note: If you use brew on macOS, you can install via brew install jmeter.

3. Start JMeter in your terminal: jmeter (This should launch the Apache JMeter GUI.)

4. Install the Throughput Shaping Timer a) In Apache JMeter, select Options, then Plugin Manager a) Click on Available Plugins, then search for Throughput Shaping Timer. Select it (click the checkbox), and Click Apply Changes and Restart JMeter.

5. In Apache JMeter, open the test_fast_endpoint.jmx file. Make the needed configuration changes - see the " configuration tips" section below.

Configuration Tips

• Read "How Many Threads I Need To Produce Desired RPS?"; configure the threads accordingly.
• Change the protocol, domain/IP, port number under the HTTP Request Defaults config element.
• Change the HTTP Request type and Path under the HTTP GET /fast config element.
• Change the HTTP headers under the HTTP Header Manager config element.
• Change the desired QPS / RPS under the Throughput Shaping Timer config element.
