Question

我希望我的测试尽可能完整。我正在尝试在用户的个人资料页面上使用assert_template，其中一些数据是使用Etsy Ruby Gem从Etsy API中提取的，但我似乎无法让它工作。

我在dev和prod中访问应用程序时数据显示正常。

我正在使用Webmock，并且非常感谢指点。

这是我得到的错误：

这是我的测试文件：

require 'test_helper'

  def setup
    @user = users(:michael)
    stub_request(:get, "https://openapi.etsy.com/v2/shops/livingwatersbaby?api_key=g29bmrbb1xr4tfahjgqn58wh&fields=is_vacation,is_refusing_alchemy").

    assert is_logged_in?
    assert_redirected_to @user
    follow_redirect!
  end

这是我的装备：

michael:
  name: Michael Example
  email: michael@example.com
  password_digest: <%= User.digest('password') %>
  admin: true
  activated: true
  activated_at: Time.zone.now
  oauth_verifier: 'hidden'
  oauth_token: 'secret'
  request_secret: 'hidden'
  login_name: 'littlejane'

错误来自Etsy Gem，通常表示错误的身份验证令牌，但夹具的oauth_verifier，oauth_token和request_secret都是最新且正确的。有没有更好的方法来存根外部API调用或我做错了什么？非常感谢你。

Answer 1

看起来您的存根都返回空字符串作为结果：

stub_request(:get, "https://openapi.etsy.com/v2/shops/livingwatersbaby?api_key=g29bmrbb1xr4tfahjgqn58wh&fields=is_vacation,is_refusing_alchemy").
  with(  headers: {
    'Accept'=>'*/*',
    'Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3',
    'User-Agent'=>'Ruby'
    }).
  to_return(status: 200, body: "", headers: {})

请注意body: ""。

部分

""无效JSON，因此您收到EtsyJSONInvalid错误。

当我在做存根时，我常常做类似的事情：

response = JSON.dump({some: {valid: :hash}})

stub_request(:get, "https://openapi.etsy.com/v2/shops/livingwatersbaby?api_key=g29bmrbb1xr4tfahjgqn58wh&fields=is_vacation,is_refusing_alchemy").
  with(  headers: {
    'Accept'=>'*/*',
    'Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3',
    'User-Agent'=>'Ruby'
    }).
  to_return(status: 200, body: response, headers: {})

而不是：

stub_request(:get, "https://openapi.etsy.com/v2/shops/livingwatersbaby?api_key=g29bmrbb1xr4tfahjgqn58wh&fields=is_vacation,is_refusing_alchemy").
  with(  headers: {
    'Accept'=>'*/*',
    'Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3',
    'User-Agent'=>'Ruby'
    }).
  to_return(status: 200, body: JSON.dump({some: {valid: :hash}}), headers: {})

就我个人而言，我发现在设置与存根分开的响应时，视觉上的混乱程度稍微低一些。但是，这是一个问题或个人偏好。

事实上，我经常将存根移动到他们自己的方法中，例如：

require 'test_helper'
require 'etsy'
# Tests user login

class UsersLoginTest < ActionDispatch::IntegrationTest

  def setup
    @user = users(:michael)
    stub_foo
    stub_bar
    stub_baz
  end

  test "login with valid information followed by logout" do
    get login_path
    post login_path, params: { session: { email:    @user.email,
                                          password: 'password' } }
    assert is_logged_in?
    assert_redirected_to @user
    follow_redirect!
  end

  private 

    def stub_foo
      response = JSON.dump({some: {valid: :hash}})

      stub_request(:get, "https://openapi.etsy.com/v2/shops/livingwatersbaby?api_key=mY-4p1-k3y&fields=is_vacation,is_refusing_alchemy").
        with(headers: {
          'Accept'=>'*/*',
          'Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3',
          'User-Agent'=>'Ruby'
          }).
        to_return(status: 200, body: response, headers: {})
    end

    def stub_bar
      response = JSON.dump({some_other: {valid: :hash}})

      stub_request(:get, "https://openapi.etsy.com/v2/users/?api_key=mY-4p1-k3y").
        with(headers: {
          'Accept'=>'*/*',
          'Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3',
          'User-Agent'=>'Ruby'
        }).
        to_return(status: 200, body: response, headers: {})
    end

    def stub_baz
      response = JSON.dump({yet_another: {valid: :hash}})

      stub_request(:get, "https://openapi.etsy.com/v2/users/suellykirjner?api_key=mY-4p1-k3y").
        with(headers: {
          'Accept'=>'*/*',
          'Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3',
          'User-Agent'=>'Ruby'
          }).
        to_return(status: 200, body: response, headers: {})
    end

end

同样，我发现它在视觉上更加混乱。
