end|code-block|syntax|javascript|684023|我没有使用cancan，所以这部分我帮不上忙。|684024|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

This is how I do this:

<pre><code>describe "GET index" do
 it "returns correct JSON" do
 # @groups.should have(2).items
 get :index, :format =&gt; :json
 response.should be_success
 body = JSON.parse(response.body)
 body.should include('group')
 groups = body['group']
 groups.should have(2).items
 groups.all? {|group| group.key?('customers_count')}.should be_true
 groups.any? {|group| group.key?('customer_ids')}.should be_false
 end
end
</code></pre>

I'm not using cancan, therefore I cannot help with this part.

blocks|key|900562|text|要断言JSON，您也可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|900563|ActiveSupport::JSON.decode(response.body).should+==+ActiveSupport::JSON.decode(
++{"error"+=>+"&nbsp;An+email+address+is+required&nbsp;"}.to_json
)|code-block|syntax|javascript|900564|This博客给出了更多的想法。|offset|length|900565|entityMap|0|LINK|mutability|MUTABLE|url|http://www.idolhands.com/ruby-on-rails/specs-and-testing/writing-specs-for-controller-actions-that-return-json^0|0|0|0|4|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@]|9|@$I|V|J|W|1|X]]|A|$]]|$1|K|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|L|$M|$5|N|O|P|A|$Q|R]]]]

To assert JSON you can do this too:

<pre><code>ActiveSupport::JSON.decode(response.body).should == ActiveSupport::JSON.decode(
 {"error" =&gt; "&amp;nbsp;An email address is required&amp;nbsp;"}.to_json
)
</code></pre>

<a href="http://www.idolhands.com/ruby-on-rails/specs-and-testing/writing-specs-for-controller-actions-that-return-json" rel="nofollow noreferrer">This</a> blog gives some more ideas.

blocks|key|900583|text|试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|900584|_expected+=+{:order+=>+order.details}.to_json
response.body.should+==+_expected|code-block|syntax|javascript|900585|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Try this:

<pre><code>_expected = {:order =&gt; order.details}.to_json
response.body.should == _expected
</code></pre>

blocks|key|684120|text|有时，验证response是否包含有效的JSON并显示实际响应可能已经足够好了，下面是一个示例：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|684121|it+'responds+with+JSON'+do
++expect+{
++++JSON.parse(response.body)
++}.to_not+raise_error,+response.body
end|code-block|syntax|javascript|684122|entityMap^0|5|8|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

Sometimes it might be good enough to verify if <code>response</code> contains valid JSON and to show actual response otherwise, here is an example:

<pre><code>it 'responds with JSON' do
 expect {
 JSON.parse(response.body)
 }.to_not raise_error, response.body
end
</code></pre>

blocks|key|900662|text|我认为您要做的第一件事是检查响应的类型是否正确，即是否将Content-Type标头设置为application/json，如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|900663|it+'returns+JSON'+do
++expect(response.content_type).to+eq(Mime::JSON)
end|code-block|syntax|javascript|900664|然后，根据您的情况，您可能希望检查响应是否可以像wik建议的那样解析为JSON：|900665|it+'responds+with+JSON'+do
++expect+{
++++JSON.parse(response.body)
++}.to_not+raise_error
end|900666|如果您觉得检查JSON响应有效性的两个测试太多，可以将以上两个合并为一个测试。|900667|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/20246051/505650^0|S|C|19|G|0|0|O|3|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@$9|Z|A|10|B|C]|$9|11|A|12|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|13|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|14|8|@]|D|@$9|15|A|16|1|17]]|E|$]]|$1|M|3|N|5|H|7|18|8|@]|D|@]|E|$I|J]]|$1|O|3|P|5|6|7|19|8|@]|D|@]|E|$]]|$1|Q|3|-4|5|6|7|1A|8|@]|D|@]|E|$]]]|R|$S|$5|T|U|V|E|$W|X]]]]

I think the first thing you want to do is to check that the response is of the correct type, i.e. that it has the <code>Content-Type</code> header set to <code>application/json</code>, something along the lines of:

<pre><code>it 'returns JSON' do
 expect(response.content_type).to eq(Mime::JSON)
end
</code></pre>

Then, depending on your case, you might want to check whether the response can be parsed as JSON, like <a href="https://stackoverflow.com/a/20246051/505650">wik</a> suggested:

<pre><code>it 'responds with JSON' do
 expect {
 JSON.parse(response.body)
 }.to_not raise_error
end
</code></pre>

And you could merge the above two into a single test if you feel like two tests for checking JSON response validity are too much.

I have a Groups Controller with a method <code>def inbox.</code>

If the user is a group member then inbox returns a JSON object.

If the user is not a member, then inbox should redirect thanks to CanCan permissions.

How do I write an rspec to test these two use cases?

Current spec:

<pre><code>require 'spec_helper'

describe GroupsController do
 include Devise::TestHelpers

 before (:each) do
 @user1 = Factory.create(:user)
 @user1.confirm!
 sign_in @user1
 @group = Factory(:group)
 @permission_user_1 = Factory.create(:permission, :user =&gt; @user1, :creator_id =&gt; @user1.id, :group =&gt; @group)
 end

 describe "GET inbox" do
 it "should be successful" do
 get inbox_group_path(@group.id), :format =&gt; :json
 response.should be_success
 end
 end
end
</code></pre>

Routes:

<pre><code>inbox_group GET /groups/:id/inbox(.:format) {:controller=&gt;"groups", :action=&gt;"inbox"}
</code></pre>

Routes File:

<pre><code>resources :groups do
 member do
 get 'vcard', 'inbox'
 end
 ....
end
</code></pre>

How do I create an rspec test that validates a JSON response?

我有一个带有def inbox.方法的组控制器如果用户是组成员，则inbox返回一个JSON对象。如果用户不是成员，则由于CanCan权限，收件箱应该重定向。如何编写rspec来测试这两个用例？当前规格：require 'spec_helper'describe GroupsController do  include...
