RSpec is a behavior-driven development (BDD) framework for Ruby. This meta-package includes the RSpec test runner, along with the expectations and mocks frameworks.

Rspec-mocks provides RSpec's "test double" framework, with support for stubbing and mocking.

Docile is a Ruby library that provides an interface for creating embedded domain specific languages (EDSLs) that manipulate existing Ruby classes.

Sequel provides thread safety, connection pooling and a concise DSL for constructing SQL queries and table schemas. It includes a comprehensive ORM layer for mapping records to Ruby objects and handling associated records.

Builder provides a number of builder objects that make it easy to create structured data. Currently the following builder objects are supported: XML Markup and XML Events.

Rspec-core provides the RSpec test runner and example groups.

The mime-types library provides a library and registry for information about Multipurpose Internet Mail Extensions (MIME) content type definitions. It can be used to determine defined filename extensions for MIME types, or to use filename extensions to look up the likely MIME type definitions.

Cucumber Messages for Ruby is a library which allows serialization and deserialization of the protocol buffer messages used in Cucumber.

Given_core is the basic functionality behind rspec-given and minitest-given, extensions that allow the use of Given/When/Then terminology when defining specifications.

Cucumber's wire protocol allows step definitions to be implemented and invoked on any platform.

Rake is a Make-like program where tasks and dependencies are specified in standard Ruby syntax.

Cucumber HTML Formatter produces a HTML report for Cucumber runs. It is built on top of cucumber-react and works with any Cucumber implementation with a protocol buffer formatter that outputs Cucumber messages.

Cucumber is a tool for running automated tests written in plain language. Because they're written in plain language, they can be read by anyone on your team. Because they can be read by anyone, you can use them to help improve communication, collaboration and trust on your team.

Hoe is a rake/rubygems helper for project Rakefiles. It helps manage, maintain, and release projects and includes a dynamic plug-in system allowing for easy extensibility. Hoe ships with plug-ins for all the usual project tasks including rdoc generation, testing, packaging, deployment, and announcement.

Minitest-hooks adds around, before_all, after_all, around_all hooks for Minitest. This allows, for instance, running each suite of specs inside a database transaction, running each spec inside its own savepoint inside that transaction. This can significantly speed up testing for specs that share expensive database setup code.

Sorcerer generates Ruby code from a Ripper-like abstract syntax tree (i.e. S-Expressions). Sorcerer is targeted mainly at small snippets of Ruby code, expressible in a single line. Longer examples may be re-sourced, but they will be rendered in a single-line format.

The Cucumber Compatibility Kit (CCK) aims to validate a Cucumber implementation's support for the Cucumber Messages protocol.

MiniTest Moar add some additional features and changes some default behaviours in MiniTest. For instance, Moar replaces the MiniTest Object#stub with a global stub method.

Mini-portile is a port/recipe system for Ruby developers. It provides a standard way to compile against specific versions of libraries to reproduce user environments.

This module provides a String#unindent Ruby method to unindent strings, which can be useful to unindent multiline strings embedded in already-indented code.

Minitest bonus assertions provides extra MiniTest assertions. For instance, it provides assert_true, assert_false and assert_set_equal.

This package provides a Ruby interface for secure random number generators.

This package provides support for encoding and decoding binary data using a Base64 representation.

This package provides a collection of RuboCop cops to check for performance optimizations in Ruby code.
