Pattern: Missing use of all matcher

Issue: -

Description

Checks that all matcher is used instead of iterating over an array.

Examples

# 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
