let g:test#ruby#rails#executable = 'docker compose run -ti --rm backend-test rails test'

# Replace backend-test with the name of the service.
You wouldn't want to run it in the main service because it ends up using the resetting development database.

Install notes for Manjaro

1. Install broadcom-wl-dkms to get 5G. Default installed kernel linux56 didn't have kernel headers to install the dkms module. So had to upgrade to new kernel.

sudo mhwd -i linux58
sudo pacman -S linux58-headers
sudo pacman -S broadcom-wl-dkms

# must do `pip install hdrhistogram`
# uses package https://github.com/HdrHistogram/HdrHistogram_py

# This file can be used to convert a csv with one column (latency / other time metric)
# into hgrm file format which can then be plotted with http://hdrhistogram.github.io/HdrHistogram/plotFiles.html
#
# Useful to download data from Splunk an generate Percentile distribution
from hdrh.histogram import HdrHistogram
