You can not use the hash_including
argument matcher
Show archive.org snapshot
with a nested hash:
describe 'user' do
let(:user) { {id: 1, name: 'Foo', thread: {id: 1, title: 'Bar'} }
it do
expect(user).to match(
hash_including(
id: 1, thread: {id: 1}
)
)
end
end
The example will fail and returns a not very helpful error message:
expected {:id => 1, :name => "Foo", :thread => {:id => 1, :title => "Bar"}} to include hash_including(:id => 1, :thread => {:id => 1})

Instead you need to do something like this:
describe 'user' do
let(:user) { {id: 1, name: 'Foo', thread: {id: 1, title: 'Bar'}} }
it do
expect(user).to include(
id: 1,
thread: hash_including(id: 1)
)
end
end
Or nest multiple hash including:
describe 'user' do
let(:user) { {id: 1, name: 'Foo', thread: {id: 1, title: 'Bar'} }
it do
expect(user).to match(
hash_including(
id: 1, thread: hash_including(id: 1)
)
)
end
end
Note:
-
RSpec will highlight
array_includingandhash_includingmatches with red even they should be green if a test fails. You need to find out manually where the result differs from the expectation. -
If you want to match an
ActiveRecordrelation you have to map the attributes and mutate for indifferent access or use string hash keys
users.map(&:attributes).to include(hash_including('name' => 'Some name'))
