Welcome to our next step in mastering Test Driven Development (TDD) with Ruby, where we will focus on setting up a robust testing environment using RSpec
. As you might recall, the TDD process involves the Red-Green-Refactor cycle — starting with a failing test, writing the minimum code needed to pass it, and then refining the implementation. In this lesson, we will set up the tools necessary for testing with RSpec
, guiding you on how to create an efficient testing environment that complements the TDD cycle.
RSpec
is a popular Ruby testing framework known for its readability and expressiveness. This lesson will offer a systematic guide to setting up your environment for efficient testing using RSpec
.
Setting up RSpec
is a straightforward process, allowing you to get started with minimal configuration. Begin by adding RSpec
to your Gemfile:
Then run the following command to install it:
Once installed, you can initialize RSpec
in your project by executing:
This command will create a basic setup with a file for configuration and a directory for your test files. By keeping configurations simple and using command-line options, you can focus on writing and running tests, maintaining emphasis on the TDD process: Red-Green-Refactor.
