appraisal - A Ruby library for testing your library against different versions of dependencies.

•    Ruby

Find out what your Ruby gems are worth. Appraisal integrates with bundler and rake to test your library against different versions of dependencies in repeatable scenarios called "appraisals." Appraisal is designed to make it easy to check for regressions in your library without interfering with day-to-day development using Bundler.

factory_bot - A library for setting up Ruby objects as test data.

•    Ruby

Ruby gem to handle settings for ActiveRecord instances by storing them as serialized Hash in a separate database table. Namespaces and defaults included. Version 2 is a complete rewrite and has a new DSL, so it's not compatible with Version 1. In addition, Rails 2.3 is not supported anymore. But the database schema is unchanged, so you can continue to use the data created by 1.x, no conversion is needed.

leaky-gems - A list of Ruby gems that have known memory leaks (and issues)

Your Ruby app leaks memory if you see gems above in your Gemfile.lock. The list above may save you a week or more of your personal life. It appears some contributors submit gems with known memory issues, but not actual leaks. While those issues don't qualify as leaks they may still be important. I prefer listing them here to help other developers rather than just hiding them.

puppet-module-gems - A project for generating dependency management gems

•    Ruby

Puppet Module Gems is a utility that generates gemspecs and builds management gems based on a YAML-based configuration. The purpose for these gems is to reduce the amount of changes required to sync shared dependencies across multiple modules’ Gemfiles.For example, when a dependency gem publishes a new release that requires Ruby 2.3.3, this would normally break all modules that install this gem that run on a version of Ruby less than 2.3.3. To fix this previously, you would need a modulesync to pin the gem to a compatible version. With these new gem management gems, you can instead update the gem version pin in a configuration YAML. The gem management will then build and publish to rubygems, and a bundle update fixes all affected modules.

pkgbot

•    Javascript

A statistics slack bot for npm packages and ruby gems The bot will fetch information from npmjs or rubygems and show it on screen.Before creating the pkgbot, you need to create a new Slack bot and record your API token, export it as an environment variable named SLACK_TOKEN.
