Expera JMeter Performance Testing

Project Description

This project focuses on performance testing using Apache JMeter and Docker to evaluate and analyze the performance of web applications. The test plan includes multiple HTTP requests, configuration elements, and result collectors to measure response times, throughput, and error rates.

Technologies Used

• Apache JMeter (Version 5.0)
• Docker (Containerized JMeter setup)
• HTTP Request Load Testing
• SMOTE-based Data Balancing (for generating synthetic data in tests)
• Performance Monitoring (JMeter Summary Reports, Aggregate Graphs)

Key Components

1. JMeter Test Plan Overview

• Test Plan Elements:
  • User Defined Variables: Set up global test variables.
  • Thread Group: Defines the number of users and ramp-up time.
  • HTTP Request Defaults: Standardized HTTP settings for requests.
  • HTTP Cookie Manager: Manages session persistence.
  • Result Collectors: Captures test results in various formats.

2. Performance Testing Steps

• Load Testing: Simulated concurrent users making HTTP requests.
• Stress Testing: Evaluated application limits by increasing user load.
• Response Time Analysis: Measured time taken for different requests.
• Throughput Calculation: Determined the number of requests handled per second.

3. JMeter Configuration

• Used Thread Groups to simulate concurrent users.
• Defined Loop Controllers to control test iterations.
• Implemented Assertions to validate expected response codes.
• Configured HTTP Headers for request optimization.

4. Docker Integration

• Used Dockerized JMeter to ensure consistent execution across environments.
• Ran JMeter tests inside a containerized environment.
• Simplified deployment and scalability using Docker Compose.

Findings & Insights

• Identified Performance Bottlenecks: Analyzed slow response times under high load.
• Optimized API Endpoints: Suggested improvements for API request handling.
• Scalability Analysis: Determined system’s ability to handle increased users.
• Error Rate Reduction: Adjusted server-side configurations to reduce failures.

Future Enhancements

• Automated Performance Testing Pipelines (CI/CD Integration with JMeter)
• Enhanced Reporting Dashboards (Grafana, InfluxDB Integration)
• Dynamic Load Testing with AI-based Traffic Simulation

Jmeter Docker Image

Build and Run docker jmeter images as below

docker build -t jmeter-docker:latest .

To store the results into your local machine use volumes as below

docker run -v {add-complete-path}/reports:/output jmeter-docker:latest

Note:

Create a new folder in the directory by name 'reports' and add the complete path in docker file-sharing prefrences
