我正在创建一个rspec测试,以查看create方法中的实例变量是否保留了构建的数据。但是,我的测试不起作用,因为我带着这个错误返回...
Failure/Error: assigns[:micropost]should eq(@post)
expected: #<Micropost id: 1, content: "Hello there", user_id: 1>
got: #<Micropost id: 2, content: "Hello there", user_id: 1>
我的rspec测试是
describe ::MicropostsController do
before :each do
@post = FactoryGirl.create(:micropost)
end
it "tests the instance variable in create method" do
post :create, micropost: FactoryGirl.attributes_for(:micropost)
assigns(:micropost).should eq(@post)
end
我的FactoryGirl文件是
FactoryGirl.define do
factory :micropost do
content "Hello there Bob!"
user_id "1"
#even if I got rid of the double quotations around 1, the stringify key error still
#pops up
end
end
这是微博控制器创建动作代码......
def create
@micropost = Micropost.new(params[:micropost])
respond_to do |format|
if @micropost.save
format.html { redirect_to @micropost, notice: 'Micropost was successfully create.'
}
else
format.html { render action: "new" }
end
end
end

如果你想测试是否创建了微博,你必须将一些参数传递给post动作,在你的测试中你只构建一个新的Micropost(在内存中,没有保存),你的创建动作甚至都不知道它存在:
我应该这样做:
before(:each) do
@micro_mock = mock(:micropost)
@micro_mock.stub!(:save => true)
end
it "creates a micropost" do
params = {:micropost => {:something => 'value', :something2 => 'value2'}}
Micropost.should_receive(:new).with(params).and_return(@micro_mock)
post :create, params
end
it "assigns the created micropost to an instance variable" do
Micropost.stub!(:new => @micro_mock)
post :create
assigns(:micropost).should == @micro_mock
end
你应该测试重定向和flash消息(在需要时将save方法存根为true / false)

您在micropost
中获得了零值,因为您尚未在此行中发布任何数据:
post '/microposts'
您需要实际包含此数据:
post '/microposts', :micropost => p
