如果散列数组具有属性/值对，如何编写rspec测试

user_config = {
  name: "Alice",
  age: 30,
  role: "admin"
}

require 'rspec'

describe 'User Configuration' do
  let(:user_config) do
    {
      name: "Alice",
      age: 30,
      role: "admin"
    }
  end

  it 'should have the correct name' do
    expect(user_config[:name]).to eq("Alice")
  end

  it 'should have the correct age' do
    expect(user_config[:age]).to eq(30)
  end

  it 'should have the correct role' do
    expect(user_config[:role]).to eq("admin")
  end

  it 'should include the key :name' do
    expect(user_config).to include(:name)
  end

  it 'should include the key :age' do
    expect(user_config).to include(:age)
  end

  it 'should include the key :role' do
    expect(user_config).to include(:role)
  end
end
