Question

我有一个控制器动作，我想测试一些实例变量，这是我的动作代码：

def index
    @users_list = get_response('accounts/by_tag/QuickcallAdmin')['users'].to_a
    @credit_admin = !@users_list.select{|h| h['email'] == current_user.email}.blank?
    @accounts_emails = Account.pluck(:email)
  end

和规范代码：

describe 'GET #index' do
    login_user
    let(:account) {create(:account)}

    it 'responds with 200' do
      get :index, :format => :html
      controller.instance_variable_set(:@users_list, [{"id"=>2, "email"=>"tes1@test.com", "tenant_id"=>1,"first_name"=>"valera","last_name"=>"rotari","phone_number"=>"89439438954", "tags"=>[{"name"=>"Program", "value"=>"my_company"}, {"name"=>"ProgramAdmin", "value"=>"new_program"}, {"name"=>"ProgramAdmin", "value"=>"new_program1"}, {"name"=>"QuickcallAdmin", "value"=>"q1"}, {"name"=>"CreditAdmin", "value"=>"q1"}]}])

      expect(assigns(:credit_admin)).to eql(true)
      expect(assigns(:accounts_emails)).to eql(["tes1@test.com"])
    end
  end

因此你可以看到我尝试分配一些我通常从api调用的响应中得到的哈希值，之后看看credit_admin和account_emails vars是否具有正确的值。问题是如果我在var赋值之后推出一些put in spec我看到我的值已分配，但测试失败，因为credit admin变量为false并且预期为true。我得到了相同的代码，并把它作为rails控制台为自己做一个测试，注意我使用相同的哈希，我有正确的真值。所以似乎@users_list var没有正确分配或类似的东西。另外@account_email是空数组，但是我有从工厂创建的帐号，所以它应该有一些值，看起来像是两者的常见问题

所以我以另一种方式做到了，将我的规范代码更改为

describe 'GET #index' do
    login_user

    it 'responds with 200' do
      create(:account)
      allow(controller).to receive(:get_response).and_return({"users" => [{"id"=>2, "email"=>"tes1@test.com","tenant_id"=>1,"first_name"=>"valera","last_name"=>"rotari","phone_number"=>"89439438954","tags"=>[{"name"=>"Program", "value"=>"my_company"}, {"name"=>"ProgramAdmin", "value"=>"new_program"}, {"name"=>"ProgramAdmin", "value"=>"new_program1"}, {"name"=>"QuickcallAdmin", "value"=>"q1"}, {"name"=>"CreditAdmin", "value"=>"q1"}]}]})
      get :index, :format => :html

      expect(assigns(:credit_admin)).to eql(true)
      expect(assigns(:accounts_emails)).to eql(["tes1@test.com"])
    end
  end

rspec无法获得实例var
