在Rails中，你如何测试Javascript响应格式？(In Rails, how do you functional test a Javascript response format?)

在Rails中，你如何测试Javascript响应格式？(In Rails, how do you functional test a Javascript response format?)

如果你的控制器动作如下所示：

respond_to do |format| format.html { raise 'Unsupported' } format.js # index.js.erb end

你的功能测试如下所示：

test "javascript response..." do get :index end

它会执行respond_to块的HTML分支。

如果你尝试这样做：

test "javascript response..." do get 'index.js' end

它在没有运行控制器操作的情况下执行视图（index.js.erb）！

If your controller action looks like this:

respond_to do |format| format.html { raise 'Unsupported' } format.js # index.js.erb end

and your functional test looks like this:

test "javascript response..." do get :index end

it will execute the HTML branch of the respond_to block.

If you try this:

test "javascript response..." do get 'index.js' end

it executes the view (index.js.erb) withOUT running the controller action!

最满意答案

以正常的参数传递:format ，以此格式触发响应。

get :index, :format => 'js'

无需混淆您的请求标题。

Pass in a :format with your normal params to trigger a response in that format.

get :index, :format => 'js'

No need to mess with your request headers.
