A simple CLI load testing tool.

Author - Arnab Roy

Installation

Install using pip:

$ pip install assault==1.0.0

Usage

The simplest usage of assault requires only a URL to test against and 500 requests synchronously (one at a time). This is what it would look like:

$ assault https://example.com
.... Done!
--- Results ---
Successful requests     500
Slowest                 0.010s
Fastest                 0.001s
Average                 0.003s
Total time              0.620s
Requests Per Minute     48360
Requests Per Second     806

If we want to add concurrency, we'll use the -c option, and we can use the -r option to specify how many requests that we'd like to make:

$ assault -r 3000 -c 10 https://example.com
.... Done!
--- Results ---
Successful requests     3000
Slowest                 0.010s
Fastest                 0.001s
Average                 0.003s
Total time              2.400s
Requests Per Minute     90000
Requests Per Second     1250

If you'd like to see these results in JSON format, you can use the -j option with a path to a JSON file:

$ assault -r 3000 -c 10 -j output.json https://example.com
.... Done!

Development

For working on assult, you'll need to have Python >= 3.7 (because we'll use asyncio) and pipenv installed. With those installed, run the following command to create a virtualenv for the project and fetch the dependencies:

$ pipenv install --dev
...

Next, activate the virtualenv and get to work:

$ pipenv shell
...
(assault) $
