Performance Testing Scripts – Login & Register Interfaces - SVV_Project

1. Project Overview

This repository contains Apache JMeter performance testing scripts developed for a school group assignment.
The scripts are used to evaluate the performance, concurrency handling, and stability of the Login and Register functionalities implemented by our project team.

Three separate JMeter test plans are provided to cover different testing scenarios:

• Login interface performance testing
• Register interface performance testing
• Combined Register + Login transaction performance testing

These scripts support the performance analysis and reporting required by the course assignment.

2. Test Scripts Description

2.1 Login Interface Performance Test

Script file: login_interface.jmx

This script focuses on testing the Login API independently.

Test objectives:

• Measure response time under different concurrency levels
• Observe throughput (TPS) behavior as concurrent users increase
• Verify system stability and error rate during sustained login requests

Typical scenarios:

• Baseline performance test
• Concurrent user test
• Load and stress testing for the login interface

---

2.2 Register Interface Performance Test

Script file: register_interface.jmx

This script evaluates the Register API, which involves input validation and database write operations.

Test objectives:

• Measure registration response time
• Identify performance bottlenecks during user registration
• Observe system behavior under repeated registration requests

Notes:

• Database cleanup may be required between test runs to avoid duplicate user conflicts.

2.3 Register + Login Transaction Performance Test

Script file: register_login_interface.jmx

This script simulates a complete user workflow, where a user registers and then immediately logs in.

Test objectives:

• Evaluate end-to-end transaction performance
• Measure combined response time for registration and login
• Analyze throughput and stability under realistic user behavior

Scenario characteristics:

• Sequential execution of Register → Login
• Higher resource usage compared to single-interface tests
• Suitable for simulating real-world user behavior

3. Test Environment

The performance tests were conducted in a controlled testing environment for academic purposes.

General assumptions include:

• Apache JMeter 5.x
• Backend service deployed on a test server
• Database populated with test data
• Test users generated dynamically or loaded using CSV Data Set Config

(Detailed environment configuration is documented in the performance test report.)

4. How to Run the Tests

1. Install Apache JMeter (version 5.x recommended).
2. Launch JMeter and open the required .jmx file.
3. Configure the following parameters:
   • Server IP / Domain
   • Port number
   • Thread Group settings (users, ramp-up time, duration)
4. (Optional) Update CSV files for test user data if applicable.
5. Start the test and monitor results using:
   • Summary Report
   • Aggregate Report
   • Response Time Graph
   • Backend Listener / PerfMon (if enabled)

5. Test Results and Analysis

Detailed test results, charts, and analysis are provided in the performance testing report submitted as part of the coursework.

Key metrics analyzed include:

• Average / 90% / 95% response time
• Throughput (TPS)
• Error rate
• System stability under sustained load

---

6. Notes

• These scripts are intended for academic and testing purposes only.
• Test parameters may need adjustment depending on the deployment environment.
• Performance results may vary based on system configuration and server load.
