rspec create list

To create a list using RSpec in Ruby, you can follow these steps:

First, make sure you have RSpec installed in your Ruby project. You can do this by adding the rspec gem to your Gemfile and running bundle install, or by installing it globally using gem install rspec.
Next, create a new file for your RSpec test. Conventionally, RSpec test files are placed in the spec directory and have a _spec.rb suffix. For example, you could create a file named list_spec.rb in the spec directory.
In your list_spec.rb file, require the necessary files for your code. This may include the file where your list class is defined, as well as any other dependencies.
Describe the behavior of your list class using the RSpec.describe method. This method takes a string argument that describes the class or feature you're testing. For example, you could write RSpec.describe List do.
Inside the RSpec.describe block, you can define individual examples using the it method. Each example should describe one specific behavior or scenario of your list class. For example, you could write it "should be empty when first created".
Within each example block, you can write code that sets up the initial state, performs actions, and makes assertions about the expected outcome. For example, you could write expect(List.new).to be_empty.
After defining all your examples, run the RSpec test suite by executing the rspec command in your project's root directory. RSpec will run all the examples in your test file and report any failures or errors.
Analyze the test results to ensure that your list class behaves as expected. If any examples fail, you can use the error messages provided by RSpec to debug and fix the issues in your code.

By following these steps, you can create a list using RSpec in Ruby and ensure that it behaves correctly according to your specifications.
