Selenium implements the W3C WebDriver protocol to automate popular browsers. It aims to mimic the behaviour of a real user as it interacts with the application's HTML. It's primarily intended for web application testing, but any web-based task can automated.

An object-oriented testing framework

Capybara aims to simplify the process of integration testing Rack applications, such as Rails, Sinatra or Merb. It is inspired by and aims to replace Webrat as a DSL for interacting with a webapplication. It is agnostic about the driver running your tests and currently comes bundled with rack-test, Culerity, Celerity and Selenium support built in.

CasperJS is a navigation scripting & testing utility for [PhantomJS](http://www.phantomjs.org/). It eases the process of defining a full navigation scenario and provides useful high-level functions, methods & syntaxic sugar for doing common tasks.

You probably meant `gem install rails-dom-testing`.

Sunspot::Solr provides a bundled Solr distribution for use with Sunspot. Typical deployment environments will require more configuration, but this distribution is well suited to development and testing.

NUnit is a unit-testing framework for all .Net languages. Initially ported from JUnit, the current production release, version 2.5, is the sixth major release of this xUnit based unit testing tool for Microsoft .NET. It is written entirely in C# and has been completely redesigned to take advantage of many .NET language features, for example custom attributes and other reflection related capabilities. NUnit brings xUnit to all .NET languages.

InSpec provides a framework for creating end-to-end infrastructure tests. You can use it for integration or even compliance testing. Create fully portable test profiles and use them in your workflow to ensure stability and security. Integrate InSpec in your change lifecycle for local testing, CI/CD, and deployment verification. Packaged distributions of Progress® Chef® products obtained from RubyGems are made available pursuant to the Progress Chef EULA at https://www.chef.io/end-user-license-agreement, unless there is an executed agreement in effect between you and Progress that covers the Progress Chef products ("Master Agreement"), in which case the Master Agreement shall govern. Source code obtained from the Chef GitHub repository is made available under Apache-2.0, a copy of which is included.

Test Kitchen is an integration tool for developing and testing infrastructure code and software on isolated target platforms.

Hypothesis is a powerful, flexible, and easy to use library for property-based testing.

minitest provides a complete suite of testing facilities supporting TDD, BDD, mocking, and benchmarking. "I had a class with Jim Weirich on testing last week and we were allowed to choose our testing frameworks. Kirk Haines and I were paired up and we cracked open the code for a few test frameworks... I MUST say that minitest is *very* readable / understandable compared to the 'other two' options we looked at. Nicely done and thank you for helping us keep our mental sanity." -- Wayne E. Seguin minitest/test is a small and incredibly fast unit testing framework. It provides a rich set of assertions to make your tests clean and readable. minitest/spec is a functionally complete spec engine. It hooks onto minitest/test and seamlessly bridges test assertions over to spec expectations. minitest/benchmark is an awesome way to assert the performance of your algorithms in a repeatable manner. Now you can assert that your newb co-worker doesn't replace your linear algorithm with an exponential one! minitest/mock by Steven Baker, is a beautifully tiny mock (and stub) object framework. minitest/pride shows pride in testing and adds coloring to your test output. I guess it is an example of how to write IO pipes too. :P minitest/test is meant to have a clean implementation for language implementors that need a minimal set of methods to bootstrap a working test suite. For example, there is no magic involved for test-case discovery. "Again, I can't praise enough the idea of a testing/specing framework that I can actually read in full in one sitting!" -- Piotr Szotkowski Comparing to rspec: rspec is a testing DSL. minitest is ruby. -- Adam Hawkins, "Bow Before MiniTest" minitest doesn't reinvent anything that ruby already provides, like: classes, modules, inheritance, methods. This means you only have to learn ruby to use minitest and all of your regular OO practices like extract-method refactorings still apply.
