RSPEC Controller Test Reconfiguration

(1) When it is necessary to re-use the test situation, you can use the Shared_examples ("describe") do end, where needed to use the It_behaves_like "describe" reuse, code written in Controller_ In the Spec.rb file

(2) A large number of reusable code can be put forward separately, placed in the spec/support/in the module, and in the Spec/spec_helper.rb file in the Rspec.configure block, add config.include Moudle, or directly under the Spec/support or sub-folder to write a RB file, SPEC_HELPER.RB will automatically require, the following code:

Dir[rails.root.join ("spec/support/**/*.rb")].each {|f| require F}

(3) You can use a custom match to simplify the code, such as the login function:

Spec/support/matchers/require_login.rb

rspec::matchers.define :require_login do |attribute|    match do  |actual|        expect (attribute) .to              redirect_to rails.application.routes.url_helpers.login_ path    end    failure_message_for_should do |actual|          "expected to require login to access  The method "    end    failure_message_for _should_not  do |actual|         "expected not to require  Login ro access the method "    end    description  do         "Redirect to the login form"      endEnd 

Use:

Expect (response) to Require_login
