#Rails + #rspec でハッシュに対して一部のkey/valueの型だけを検証する、ゆるいテストをするには include と be_an を組み合わせて使う

expect(a: 1, b: Time.now, c: 'wow').to include({a: be_a(Integer)})
# => true

expect(a: 1, b: Time.now, c: 'wow').to include({b: be_a(Time)})
# => true

expect(a: 1, b: Time.now, c: 'wow').to include({c: be_a(String)})
# => true

expect(a: 1, b: Time.now, c: 'wow').to include({c: be_a(Integer)})
# => [#<RSpec::Expectations::ExpectationNotMetError: expected {:a => 1, :b => 2019-12-13 02:08:55.283922100 +0000, :c => "wow"} to include {:c => (be a kind of Integer)}
