I would like to test one-to-many associations with Rspec.

I'm tripping on the Rspec test.
How do I write to test the association...

There are two things I don't understand.
1. I'm not sure how to associate with factorygirl in a one-to-many association (this time the bank model has many branches (model)).
2. I would like to guarantee that 20 branches linked to the bank will be created in the index test and 20 branches will be displayed on the first page, but it is not working at the moment...

      If you specify Japan for context 'name_cont' do
        let(:condition) {{name_cont:'Japan'}}
        it { is_expected.to match_array([@branch_data1])}
      end

$rake routes

bank_bank_branches GET/banks/:bank_id/bank_branches(.:format)bank_branches#index

As far as the log shows, I think the problem is that 21 bank_branch data have not been created on the create_list, but how can 21 be created...
I'm sorry to trouble you, but I'd appreciate it if you could let me know if you have any improvement measures.
Sorry for the inconvenience, but I appreciate your cooperation.

I'm sorry, but I solved it myself, so I'll let you know.

I think I made a mistake in associating the association in the first place.

factors/bank_branches.rb

FactoryGirl.definedo
  factory:bank_branch, class:BankBranch do
    sequence(:id)
    sequence(:bank_id)
    sequence(:code)
    sequence(:name) {|i | "BankBranchName#{i}"}
    sequence(:name_kana) {|i | "BankBranchNameKana#{i}"}
  end

end

spec/controllers/bank_branches_controller_spec.rb

context 'If you have 21 branch data' do
  before do
    @bank=create(:bank)#Define associations here
    create_list(:bank_branch,21,bank:@bank)
  end

  It 'The first page should have 20 cases' do
    get:index,params:{bank_id:@bank}
    expect(assigns(:bank_branches).size).toeq Settings.per_page
  end

  It's 'The second page should be one case'
    get:index,params:{bank_id:@bank,page:'2'}
    expect(assigns(:bank_branches).size).toeq1
  end
end

I'm sorry to have troubled you.Thank you to those who came up with a solution.
