通常在我的控制器规格中,我会做这样的事情:
describe MyController do
describe 'POST #create' do
let!(:my_model) { initialize_something_here }
before :each do
post :create, my_model: my_model
end
it 'should be successful' do
response.should be_successful
end
... more tests ...
end
end
我的问题是,当我执行使用块的断言时,expect
例如检查数据库中的项目计数是否在 a 之后增加create
,我必须post
从块中删除调用before :each
,如下所示并为每个it
语句重复它:
describe MyController do
describe 'POST #create' do
let!(:my_model) { initialize_something_here }
it 'should insert into database' do
expect { post :create, my_model: my_model }.to change(MyModel, :count).by(1)
end
it 'should be successful' do
post :create, my_model: my_model
response.should be_successful
end
... more tests ...
end
end
有没有一种 DRY-er 的方式来post
