[英]Rails Rspec Testing Controller New Action
I am trying to test the new action in my controller. 我试图在我的控制器中测试新动作。 At the moment it looks like this:
目前它看起来像这样:
Controller 调节器
def new
@business = Business.new
@business.addresses.build
end
Spec 规格
describe 'GET #new' do
it 'assigns a new business to @business' do
get :new
expect(assigns(:business)).to be_a_new(Business)
end
end
I would like to test the line '@business.addresses.build'. 我想测试'@ business.addresses.build'这一行。 How do I do this?
我该怎么做呢?
Thanks in advance! 提前致谢!
怎么样
expect(assigns(:business).addresses.first).to be_a_new(Address)
Assuming build is a method, you only need test to ensure that build is called. 假设构建是一种方法,您只需要测试以确保调用构建。 You could do so by replacing the new
Business
with a mock that has an addresses
attribute that expects to receive :build
. 您可以通过使用具有期望接收的
addresses
属性的模拟替换新的Business
来实现:build
。
I haven't tested this, but I suspect you could do something like: 我没有测试过这个,但我怀疑你可以这样做:
business = double('business')
addresses = double('addresses')
business.should_receive(:addresses).and_return(addresses)
addresses.should_receive(:build)
Business.stub(:new).and_return(business)
