假设我在 application_helper.rb 中有以下代码:
def do_something
if action_name == 'index'
'do'
else
'dont'
end
end
如果在 index 操作中调用,它将执行某些操作。
问:如何在 application_helper_spec.rb 中为此重写帮助程序规范以模拟来自“索引”操作的调用?
describe 'when called from "index" action' do
it 'should do' do
helper.do_something.should == 'do' # will always return 'dont'
end
end
describe 'when called from "other" action' do
it 'should do' do
helper.do_something.should == 'dont'
end
end
最佳答案
您可以将 action_name 方法 stub 为您想要的任何值:
describe 'when called from "index" action' do
before
helper.stub!(:action_name).and_return('index')
end
it 'should do' do
helper.do_something.should == 'do'
end
end
describe 'when called from "other" action' do
before
helper.stub!(:action_name).and_return('other')
end
it 'should do' do
helper.do_something.should == 'dont'
end
end
