# rfswarm-manager — RFSwarm Manager

License: copyleft · Maintenance: active · Downloads: 84.6K/mo

## What it is and what it does

rfswarm-manager is a performance and load testing tool built on Robot Framework that lets you reuse existing functional test cases for load testing. Instead of writing separate performance test scripts, you can take a Robot Framework test case designed for functional or regression testing, make minor adjustments, and execute it with multiple concurrent virtual users to generate load on an application. This bridges the gap between functional and performance testing by allowing teams to leverage the same test logic for both purposes.

The package is written in pure Python and integrates with Robot Framework's ecosystem. It depends on configparser, httpserver, matplotlib, pillow, psutil, and pyyaml to manage test execution, visualization, and system monitoring. The tool is actively maintained, marked as Production/Stable, and supports Python 3.9 and later.

Use it for:

- Run existing Robot Framework functional tests as load tests with concurrent virtual users to measure response times.
- Generate performance baselines by executing the same test case with increasing numbers of virtual users to find breaking points.
- Visualize load test results using matplotlib-based reporting to identify performance bottlenecks.
- Reuse regression test suites for performance testing without duplicating test logic across frameworks.
- Monitor system resources during load tests using psutil integration.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

rfswarm-manager lets you run Robot Framework test cases as load tests by executing them concurrently with multiple virtual users to measure application performance under load.

Yes, if you already use Robot Framework for functional testing and need load testing without maintaining separate performance test scripts. The active maintenance, low install friction, and GPL-3.0-only license are straightforward. Verify that the copyleft license aligns with your project's licensing model before committing.

## Install

pip install rfswarm-manager
uv add rfswarm-manager
poetry add rfswarm-manager

## Installing rfswarm-manager

Before you install: Low install friction with a pure-Python wheel distribution and six straightforward runtime dependencies. Active maintenance with a release 9 days ago and commits through 2026-08-12 suggest ongoing support.

License in practice: Licensed under GPL-3.0-only (copyleft). Any derivative work or distribution must also be licensed under GPL-3.0-only; proprietary or closed-source projects cannot incorporate this package without legal review.

Quickstart:

pip install rfswarm-manager

from rfswarm_manager import RFSwarmManager
manager = RFSwarmManager()
manager.run_test(test_file='test.robot', num_users=5)

Requires Python 3.9 or later. Robot Framework must be installed separately to write test cases.

Verify before relying:

- Whether the package includes a CLI entry point or if programmatic API is the primary usage pattern.
- How matplotlib and pillow are used in the load-testing workflow (e.g., for result visualization).
- Whether httpserver is a full HTTP server dependency or a lighter utility for test fixtures.
- Typical concurrency levels and performance characteristics when running multiple virtual users.
