Utility designed for check combinations of multiple binary params
Project description
# Abstract
I needed an util that create good binary params combinations set to test that I didn't broke my product. To test just 15 options in straight way there was 2^15 variants (32768). Each service restart with changed config took ten seconds.
So I recalled a method mentioned by @backendsecret about half year ago, found a library AllPairs and built my util on top of it.
# Install:
```
pip install binary-pairs
```
# Usage:
```
binary-pairs <number of params>
```
# Examples
```
