Ruby on rails 如何使用Minitest测试OmniAuth的SessionController

我正试图用Minitest测试我的facebook登录代码，但进展不顺利

当我在测试中尝试

get:auth，'provider'=>'facebook'

时，测试会为nil:NilClass返回

未定义的方法“[]”，如果我尝试
get:new
它会通过，但不会调用auth

如何使用omniauth成功重定向到auth

这是我的源代码

测试/控制器/会话\u控制器\u test.rb

require 'test_helper'

class SessionsControllerTest < ActionController::TestCase

    test '#signup_success' do
        OmniAuth.config.test_mode = true
        OmniAuth.config.mock_auth[:facebook] = OmniAuth::AuthHash.new({
            'provider' => 'facebook',
            'uid' => '123451234512345',
            'info' => {'email' => 'testuser@testmail.com', 'name' => 'test', 'image' => ''}
        })
        request.env['omniauth.env'] = OmniAuth.config.mock_auth[:facebook]

        get :auth
    end
end

需要“测试助手”
类SessionControllerTest“facebook”，
'uid'=>'123451234512345'，
'信息'=>{'电子邮件'=>'testuser@testmail.com“，”名称“=>”测试“，”图像“=>”}
})
request.env['omniauth.env']=omniauth.config.mock_auth[：facebook]
获取：auth
结束
结束

app/controllers/sessions\u controller.rb

class SessionsController < ApplicationController
    def auth
        if(env['omniauth.params']['type'] == 'signin')
            if User.find_by(uid: env['omniauth.auth'].uid)
                flash[:alert] = "Already registered"
                redirect_to :back
            else
                user = User.omniauth(env['omniauth.auth'])
                if user.save
                    session[:user_id] = user.uid
                    redirect_to root_url
                else
                    flash[:alert]="Failed to Signin"
                    redirect_to :back
                end
            end
        elsif(env['omniauth.params']['type'] == 'login')
            if User.find_by(uid: env['omniauth.auth'].uid)
                session[:user_id] = env['omniauth.auth'].uid
                redirect_to root_url
            else
                flash[:alert] = "Not registered"
                redirect_to :back
            end
        else
            redirect_to root_url
        end
    end

    def find
        redirect_to '/auth/facebook?type=login'
    end

    def new
        redirect_to '/auth/facebook?type=signin'
    end

    def destroy
        session[:user_id] = nil
        redirect_to root_url
    end
end

class sessioncontroller
我认为您可能只需要在
sessioncontroller\auth
中使用
request.env[…]
而不是
env[…]
