Defined in:

Overview

Requires ‘let`/`let!` to be declared at the top of the example group, never inside a `context`. All setup objects live at the top level.

Examples:

# bad
context 'when disabled' do
  let(:user) { create(:user) }
end

# good
let(:user) { create(:user) }

context 'when disabled' do
  before { user.disable }
end
