The command "rspec --init" is used to initialize the RSpec testing framework in a Ruby project.

RSpec is a popular and widely used testing framework in Ruby. It allows developers to write and run tests for their Ruby code in a structured and readable manner.

When you run "rspec --init" in the project directory, it initializes RSpec by creating the necessary configuration files and folders for running tests.

The command creates:

1. ".rspec" file: This file contains command line options and settings for RSpec. You can modify this file to customize various RSpec configurations.
2. "spec" directory: This directory serves as the default location for storing test files. You can create subdirectories within the "spec" directory to organize your test files.
3. "spec/spec_helper.rb" file: This file is used for configuring RSpec and loading any necessary dependencies or customizations before running the tests. You can make changes to this file to set up specific behaviors or include additional code.

Once you have run "rspec --init" and initialized RSpec, you can start writing tests in the "spec" directory and run them using the "rspec" command.
