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!
Rspec
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!
