class RuboCop::Cop::RSpec::IteratedExpectation
Check that ‘all` matcher is used instead of iterating over an array.
@example
# bad it 'validates users' do [user1, user2, user3].each { |user| expect(user).to be_valid } end # good it 'validates users' do expect([user1, user2, user3]).to all(be_valid) end
