Coverband Demo

This is a Rails 5 application to demo how to use Coverband and the features it offers.

Visit the live demo site https://coverband-demo.herokuapp.com/

Heroku Deployment

The demo site is hosted on Heroku.

• basic setup was done following the standard Heroku Rails 5 Guide

Running with JRuby

This application runs both with CRuby (MRI) or JRuby. If you want to run via JRuby you can either update the .ruby-version to have jruby... Or you can one off switch over.

rvm use jruby
bundle install
bundle exec rails s

Theme

The initial design off the demo site was pulled from a demo'ed theme, a Material Design Bootstrap 4 Theme.

• From Rails 5 to Bootstrap 4 — Responsive Admin Dashboard Template
• Hero Rails

TODO

• more realistic Rails usage: - perhaps add something to help market coverband like show tweets - showcase different collection methods - thinking I could use it to demo the code observability concept via an API with document storage to attach arbitrary data to lines of code.
• add deploy to Heroku button support
• API to collect arbitrary line usage
• API to collect perf data across CI runs
  • client would post data on each benchmark run
    • ruby_version, branch or PR name, benchmark_name, calculations -> {data_point_name, i/s, total iterations, total time}, Comparison -> {data_point_name, i/s, diff calculation, note}
• a way to toggle modes?
  • oneshot, simulated, or regular
• investigate issues with runtime data vs load data when running heroku run --app coverband-demo rake posts_cleanup (note: COVERBAND_DISABLE_AT_EXIT fixes but then doesn't track rake, hmm not entirely true, not clear)
