[英]RSpec on Controller and Stubbing
I am pretty new to using rspec and am trying to write my tests for my controllers. 我对使用rspec很陌生,并且正在尝试为我的控制器编写测试。 I have this controller (I am using mocha for stubbing):
我有这个控制器(我正在使用摩卡进行存根):
class CardsController < ApplicationController
before_filter :require_user
def show
@cardset = current_user.cardsets.find_by_id(params[:cardset_id])
if @cardset.nil?
flash[:notice] = "That card doesn't exist. Try again."
redirect_to(cardsets_path)
else
@card = @cardset.cards.find_by_id(params[:id])
end
end
end
I am trying to test this action with something like this: 我正在尝试通过以下方式测试此操作:
describe CardsController, "for a logged in user" do
before(:each) do
@cardset = Factory(:cardset)
profile = @cardset.profile
controller.stub!(:current_user).and_return(profile)
end
context "and created card" do
before(:each) do
@card = Factory(:card)
end
context "with get to show" do
before(:each) do
get :show, :cardset_id => @cardset.id, :id => @card.id
end
context "with valid cardset" do
before(:each) do
Cardset.any_instance.stubs(:find).returns(@cardset)
end
it "should assign card" do
assigns[:card].should_not be_nil
end
it "should assign cardset" do
assigns[:cardset].should_not be_nil
end
end
end
end
end
The "should assign cardset" test passes, but I cannot figure out how to properly stub this line @card = @cardset.cards.find_by_id(params[:id])
for the "should assign card" test. “应该分配卡集”测试通过了,但是我无法弄清楚如何正确地对这行
@card = @cardset.cards.find_by_id(params[:id])
进行“应该分配卡集”测试。 What is the best way of testing this action, or if I'm on the right track how would I properly stub my Model calls? 测试此操作的最佳方法是什么,或者如果我走对了,我将如何正确处理我的模型调用?
Ok, deleted a previous answer which was wrong. 好的,删除以前的答案是错误的。
First: you are stubbing find
not find_by_id
. 首先:您正在存根
find
not find_by_id
。 Although you don't need to use find_by_id since that is the default for find. 尽管您不需要使用find_by_id,因为这是find的默认设置。 So use
find
所以使用
find
Second: the before :each
ordering is going to call the get :show
before the you stub Cardset
第二:
before :each
订购都将在存根Cardset
之前调用get :show
Third: check your test.log and make sure you are not getting redirected. 第三:检查您的test.log并确保您没有被重定向。 Your
require_user
action might cause a redirect before current_user
is even set. 您的
require_user
操作可能会导致甚至在设置current_user
之前进行重定向。
class CardsController < ApplicationController
...
@card = @cardset.cards.find(params[:id])
...
end
describe CardsController, "for a logged in user" do
before(:each) do
@cardset = Factory(:cardset)
profile = @cardset.profile
controller.stub!(:current_user).and_return(profile)
end
context "and created card" do
before(:each) do
@card = Factory(:card)
end
context "with get to show" do
context "with valid cardset" do
before(:each) do
Cardset.any_instance.stubs(:find).returns(@cardset)
get :show, :cardset_id => @cardset.id, :id => @card.id
end
it "should assign card" do
assigns[:card].should_not be_nil
end
it "should assign cardset" do
assigns[:cardset].should_not be_nil
end
end
end
end
end
The stubs that I ended up looking for where these 我最终找到的存根
Cardset.stubs(:find_by_id).returns(@cardset)
@cardset.cards.stubs(:find_by_id).returns(@card)
