Ruby developers can easily find time-saving ready-made solutions with powerful features for fast web application development. One can achieve this most rapid development using ruby gems that are a useful tool and many libraries with specific functionalities that allow them to build extensive ruby applications. 

Ruby on Rails provides advanced solutions for different functionalities, and for this, there are specific ruby gems available for free. For example, you can directly get ruby gems for each function like authentication, authorisation or testing if you want to use it in your ruby app. 

In this article, I have listed some ruby gems that you can frequently use in your Ruby on Rails projects. 

Without the quality of code, any RoR application does not deliver good results. Testing allows you to maintain the quality of code evaluation of expected results. If you are working upon the Ruby project, following Ruby Gems will save your time.

##1. [Rspec](http://rspec.info/) 

Testing tool use for Ruby code. Rspec is used for behavior-driven development (BDD) and test-driven development (TDD) environment. It features neat and descriptive syntax and a perfect choice for the unit test cases for RoR projects. 

##2. [Factory_girl](https://github.com/thoughtbot/factory_bot)

It's a software library for testing data having straightforward definition syntax. You don't need to enter data every time for testing as it lets you create a factory for modules. Factory_girl library supports multiple build strategies like attribute hashes, stubbed objects, saved instances, and unsaved instances. It also helps numerous factories for the same class, such as admin_user, user, and many more, including factory inheritance. 

##3. [Capybara](https://github.com/jnicklas/capybara)

This Acceptance test framework is used with a web-based driver having a user-friendly DSL certificate. Capybara Ruby Gem conducts integrated tests that automatically emulate users' movements in a browser. Capybara runs a combination with RSpec and describes the debugging model in very few lines. You can test click-throughs, items available on the home page (enter login and password, button click for login), various form entities (dropbox, checkbox, entry fields). It also suggests multiple favorable methods for debugging.

##4. [Shoulda-matchers](https://github.com/thoughtbot/shoulda-matchers)

shoulda-matchers, the latest version is 4.4.1, released on August 26, 2020. It lets us effectively test average Rails usefulness, such as validations and associations, by composing reduced one-line tests viable with RSpec. As such, shoulda-matchers offer matchers that help designers test fundamental Rails' usefulness rapidly and without any problem.

##5. [Simplecov](https://github.com/colszowka/simplecov)

SimpleCov is a code analytical tool for Ruby and used for unit testing. However, it utilizes Ruby's underlying Coverage library to assemble code inclusion information, making preparing its outcomes a lot simpler. By giving a perfect API to channel, gathering, consolidation, organization, and show those outcomes, giving you a complete code inclusion suite that can be set up with only two or three lines of code.

##Wrapping up:
