MiniTest::Perf

Build Status Code Climate

minitest-perf stores information about your minitest runs so that you can later analyze and see where the pain points are. It's in pretty early beta status, so I'm more than glad to receive bug reports and feature suggestions.

The current version works with Minitest 5 thanks to @nateberkopec, for Minitest 4 use version 0.0.3.

Installation

Add gem 'minitest-perf' to your Gemfile.

How it works

Every test that is executed is stored in a sqlite database for later query. Just require minitest/perf somewhere in your test_helper, and you're good to go. Internally, minitest/perf includes itself as just another module and starts feeding the sqlite database.

The sqlite database is stored by default as .minitest-perf.db. It can be set using either the environment variable MINITEST_PERF_DATABASE_URL, or the DATABASE_URL.

Or setting it directly via ruby with:

Minitest::Perf.database_url = 'sqlite3://localhost/some_other_file.db'

So far only local sqlite3 databases allowed, but I'm using the database url strategy to allow for flexibility in the future.

An executable is provided that prints a very basic analysis of the information it already has, but the sqlite database is perfectly normal, so you can do your own queries.

This is an example:

TODO

These are nice to haves I'd like to implement in the future:

  • Store also in mysql
  • Web interface
