JMeter Performance Test for JSONPlaceholder API

This repository contains a JMeter project for performance testing the public JSONPlaceholder API.

The test plan simulates a realistic user workflow:

1. Fetches all posts.
2. Selects a random post from the response (using correlation).
3. Fetches the comments for the selected post.

✔️ Prerequisites

• Java (version 8 or higher) installed.
• Apache JMeter installed.
• (Recommended) JMeter's bin directory added to the system's PATH variable for easier execution.

🚀 How to Run the Test

The test is intended to be run from the command-line interface (CLI), not from the JMeter GUI.

1. Clone the repository:

   git clone [https://github.com/Nikolay-Chillev/jmeter-performance-project.git](https://github.com/Nikolay-Chillev/jmeter-performance-project.git)
   cd jmeter-performance-project

2. Run the test: Open a command-line terminal (CMD, PowerShell, bash) in the project's root directory and execute the following command:

   jmeter -n -t jsonplaceholder_load_workflow.jmx -l results/results.jtl -e -o reports/html_report

3. Customize the Load (Optional): You can override the default number of users (threads) and the ramp-up time by passing properties with the -J flag:

   # Example with 50 users ramping up over 10 seconds
   jmeter -n -t jsonplaceholder_load_workflow.jmx -Jthreads=50 -Jrampup=10 -l results/results.jtl -e -o reports/html_report

4. View the Report: Once the test is complete, open the reports/html_report/index.html file in a web browser to view the full HTML dashboard report with detailed graphs and statistics.
