RapidFire Lite: A Zero-Dependency API Load Tester

RapidFire Lite is an effective and straightforward API load testing tool, built entirely in Python 3.8 and above. With no dependencies, this utility can be executed directly from the terminal, making it highly efficient for testing HTTP APIs under load in a matter of seconds. The simplicity of RapidFire Lite allows it to run without the need for Docker, npm, or complex configuration files.

Key Features

• Zero Dependencies: The tool operates independently with no additional software or libraries required.
• Pure Python: Completely written in Python, ensuring compatibility with any system running Python 3.8+.
• Air-Gapped Environment Compatibility: Ideal for testing in environments that prohibit external dependencies.
• Single File Execution: Execute from a single script with ease—no setup required.
• No Configuration Needed: Run the tests directly without fiddling with configuration files.
• Comprehensive Reporting: Get detailed latency metrics and error rates for thorough analysis of test results.

Quick Start Guide

To run a basic test, use the following command:

python RapidFireAPI_Lite.py --url https://api.example.com --users 10 --duration 30

This command will initiate a test on the specified API URL with 10 concurrent users running for 30 seconds.

Supported Platforms

RapidFire Lite is compatible with multiple operating systems, including:

• MacOS
• Windows
• Linux

Example Commands

Below are some examples of how to use RapidFire Lite for different scenarios:

• GET Request for 10 Users:

  python RapidFireAPI_Lite.py --url https://api.example.com/endpoint --users 10
  

• POST Request with JSON Body:

  python RapidFireAPI_Lite.py \
    --url https://api.example.com/login \
    --method POST \
    --body '{"username":"test","password":"secret"}'
  

• Custom Requests: Easily handle different HTTP methods (GET, POST, PUT, DELETE) by specifying the method flag.

• Stopping Tests Early: Users can abort the test process at any time using Ctrl+C, with a summary of the data collected thus far.

Detailed Metrics

At the end of each test, RapidFire Lite provides a summary report containing valuable insights such as:

• Total requests made
• Success and failure rates
• Average and percentile latencies

FAQs

• Does it work offline? Yes, provided the target API is accessible.
• Authentication support? The Lite version allows basic testing but for authenticated APIs, consider upgrading to RapidFire Pro for enhanced features.
• How many users can be simulated? The tool can typically handle 50-200 concurrent users, depending on the system specs.

Conclusion

RapidFire Lite serves as a robust solution for quick API load testing without any prerequisites. It is well-suited for developers looking to quickly validate API performance without the overhead of complex setups. For more advanced features, consider exploring RapidFire Pro, designed for exhaustive testing needs.
