使用RSPEC呈现RABL模板时的空响应(Empty response when rendering RABL template with RSPEC)

使用RSPEC呈现RABL模板时的空响应(Empty response when rendering RABL template with RSPEC)

我有一个令人困惑的问题，我的控制器工作正常。 但是，当我使用RSPEC测试它时，它将返回一个空字符串作为响应主体。

这里是控制器：

class Api::UsersController < Api::ApplicationController def show @user = User.find(params[:id]) render 'show', status: 200 # render json: @user end end

我正在渲染的RABL模板：

object @user attributes :id, :name, :email, :phone_number, :invite_token

最后这里是我的规格：

require "spec_helper" describe Api::UsersController do it "returns user attributes" do user = FactoryGirl.create(:user, name: "Mark", email: "foo@bar.com") get :show, id: user.id expect(response.status).to eq(200) output = JSON.parse(response.body) end end

当我使用render'show'渲染RABL模板时，我的测试失败，因为response.body是一个空字符串。 但是，如果我CURL到该端点，身体回报就好了。

当我将控制器更改为：呈现json：@user时，测试通过。

谁能告诉我这里发生了什么？

提前致谢！

I'm having a perplexing problem where my controller is working fine. However, when I'm testing it with RSPEC it's returning an empty string as the response body.

Here is the controller:

class Api::UsersController < Api::ApplicationController def show @user = User.find(params[:id]) render 'show', status: 200 # render json: @user end end

And the RABL template I'm rendering:

object @user attributes :id, :name, :email, :phone_number, :invite_token

Finally here is my spec:

require "spec_helper" describe Api::UsersController do it "returns user attributes" do user = FactoryGirl.create(:user, name: "Mark", email: "foo@bar.com") get :show, id: user.id expect(response.status).to eq(200) output = JSON.parse(response.body) end end

When I use render 'show' to render the RABL template my test fails as the response.body is an empty string. However, if I CURL to that endpoint, the body returns just fine.

When I change the controller to: render json: @user the test passes.

Can anyone tell me what's going on here?

Thanks in advance!

尝试在测试的顶部添加render_views

describe Api::UsersController do render_views it "returns user attributes" do user = FactoryGirl.create(:user, name: "Mark", email: "foo@bar.com") get :show, id: user.id output = JSON.parse(response.body) expect(response.status).to eq(200) expect(output).to eq(expected_hash) end end

可能的原因：RSpec默认情况下不呈现视图来加速测试。

try to add render_views at the top of the tests

describe Api::UsersController do render_views it "returns user attributes" do user = FactoryGirl.create(:user, name: "Mark", email: "foo@bar.com") get :show, id: user.id output = JSON.parse(response.body) expect(response.status).to eq(200) expect(output).to eq(expected_hash) end end

Possible reason: RSpec do not render views by default to speed up tests.
