Test private method of controller with rspec

I have

class Api::V1::BaseController < ApplicationController
   before_filter :authenticate!

  private
  def authenticate!
    session_token = request.env["HTTP_SESSIONTOKEN"]
    @current_user = User.where(session_token: session_token).first unless session_token.blank?
    unless @current_user
      return render_json({message: "ERROR: Invalid Session"})
    end
  end

  def current_user
    @current_user
  end 
end

I am testing session_controller which inherits base_controller 

before do 
    post :create, {email: "[email protected]", user_name: "raj",password: "raj"}
    body = JSON.parse(response.body)
    @session_token = body["session_token"]
end

   describe "PUT #edit_email" do
    context "if new email already exist" do
      it "should return with a error message" do
        put :edit_email, {email: "[email protected]", new_email: "[email protected]", password: "raj"}
        body = JSON.parse(response.body)
        expect(body["message"]).to eq("email already exist")
      end
    end
  end

I am new to rspec and here I am confused about calling private authenticate method with session_token. How to call private method of controller and pass header.Thanks in advance.

You can set your env variable like following:

request.env['HTTP_SESSIONTOKEN'] = "..."

For testing your private method:

controller.instance_eval{ authenticate }.should eql ...

In Ruby/Rails and OOP in general private methods should not be tested. You should test the interface, not the implementation of private method.

Implementation could be changed with time - but the interface it provides would (most likely) not.
