rspec what is shared examples

# shared_examples are tests written in a way that you can run them in
# multiple settings; extracting common behavior between objects.

it_behaves_like "a correct object remover" do
    ...
end

# shared_contexts is any setup code that you can use to prepare a test case.
# This allows you to include test helper methods or prepare for the tests to run.
include_context "has many users to begin with"

# Example
RSpec.describe TailwindDsl::Etl::ComponentStructures::Generator do
  include_context :use_temp_folder
  include_context :has_configured_uikit
  
  it 'sample' do
