stress-testing-web-service's Introduction

Stress Testing Web Service

This project is a Rust-based web service using PostgreSQL. The service provides endpoints to manage employees. We use Siege for stress testing to measure the performance of the web service under different load conditions.

Project Setup

Prerequisites

Rust
Docker and Docker Compose
Siege

Getting Started

Set up environment variables: Create a .env file in the root directory and configure variables:
```
cp .env.example .env
```

Run the migration:

diesel setup
DATABASE_URL=<DATABASE_URL> diesel migration run

Build and run Docker containers:

docker-compose build --no-cache
docker-compose up -d

Endpoints

GET /employees: Retrieve a list of employees.
POST /employees: Add a new employee.

Stress Testing with Siege

Already created testing/urls.txt. If more test cases are needed, add them here:

http://localhost:8080/employees POST application/json {"name": "John Doe", "age": 30, "position": "Developer"}
http://localhost:8080/employees

Run Siege with different concurrency levels:
```
./testing/run_siege.sh
```

Siege Test Results

File will be saved under folder testing/results with corresponding timestamp.

Date: The timestamp when the test was run
Concurrency: The number of simultaneous users simulated during the test
Resource Availability: The percentage of requests that were successfully handled
Avg Response Time: The average time taken by the server to respond to a request
Throughput: The number of requests processed per second
