如何在RSpec

Question

我有一个端点，它响应从ActiveModelSerializer添加的对象的属性+属性。我想编写一个测试，检查响应是否有密钥。

让我们假设说对象（比如树）有这些键

expected_tree_attributes = [:height, :age, :color]

如何正确编写此测试？我能写一下：

subject { post :obtain_tree_info, { id: tree.id } }

response = JSON.parse(subject.body)
expected(response).to include(*expected_tree_attributes)

那是......可以接受吗？

请考虑使用rspec-api-matchers gem

或airborne gem

你可以这样做：

# api_matchers
response = JSON.parse(subject.body)
expect(response).to be_success
expect(response).to have_json_node(:height).with(tree.height)
expect(response).to have_json_node(:age).with(tree.age)
expect(response).to have_json_node(:color).with(tree.color)

# or

expect(response).to have_json_node(:age).with("123")

机载

describe 'sample spec' do
  it 'should validate types' do
    post '/api/v1/obtain_tree_info', {id: tree.id}
    expect_json_types(height: :int, age: :int_or_null, color: :string)
  end
end
