Testing in Ruby

Testing your Ruby code with Unit and Integration testing libraries 🤩

Writing test cases is one way to ensure that your code behaves as expected, but it can be very time consuming.
That's why I'm excited to share the latest libraries I'm using to make testing my Ruby code easier and faster.
Unit testing libraries like Minitest and RSpec allow developers to precisely test small pieces of their code (e.g. a single method) and integration testing libraries like Capybara help you run tests on entire web applications by simulating user actions.
These tools are incredibly useful for finding bugs in your code that might not be obvious at first glance!


Have you ever been amazed by the power of RSpec unit tests written in Ruby code? Try it out and you'll be hooked!
When we write RSpec tests, we specify a set of expectations that define the expected behavior of our application. We can also use them to test for edge cases such as unexpected inputs and other scenarios that may cause our app to crash or respond strangely.
RSpec uses a DSL (domain specific language) to describe each test. This allows us to write expressive tests that are readable by non-technical people as well.
With RSpec, we can ensure that our application behaves correctly in all scenarios, so we can focus on developing features knowing that our code is reliable.
Give it a try and see how powerful and fun writing unit tests can be!


If you're an aspiring Ruby developer, you never want to miss the opportunity for integration testing with Capybara. Not only is it autonomous and easy to use, but it also makes testing more efficient and successful. This forward-thinking tool supports cross-browser functionality, accurately simulates user interaction on your website, and even has its own DSL. With Capybara, you can be rest assured that your code is running exactly as it should - and that's something every Ruby developer should be excited about!

It's the perfect way to make sure your applications are working as expected, from logging in to filling out forms to clicking buttons - it covers it all.
Integration testing with Capybara is fast, effective and provides you with a comprehensive overview of how the application is going to work once released. It also ensures that everything from the front end design down to the backend functionality is working as expected - and that's what makes it so great.
