⚙️ Override RSpec Configuration at Runtime​

Sometimes you need to tweak RSpec settings for a subset of your suite, such as enabling color or custom formatters only for certain directories. You can override configuration within example groups by using RSpec.describe metadata hooks. This preserves global defaults while allowing local adjustments.

# spec/special/spec_helper_override.rb
RSpec.configure do |config|
  config.add_formatter('documentation') if ENV['VERBOSE_SPECS']
end

# In a spec file
tags = { verbose: true }
RSpec.describe 'Special cases', tags do
  around do |example|
    RSpec.configuration.color = false
    example.run
    RSpec.configuration.color = true
  end

  it 'runs without color' do
    expect(true).to be_truthy
  end
end
