[英]How write rspec test for state_machine transition callback
I have spree Adjustment extension 我有大礼包调整扩展
Spree::Adjustment.class_eval do
state_machine do
after_transition :to => :closed, :do => :some_method
end
def some_method
end
end
And I have rspec test, which fails. 我有rspec测试,但失败了。 In real application method are called and all things work as expected.
在实际的应用程序中,方法被调用,并且所有事物都按预期工作。
describe Spree:Adjustment do
let(:adjustment) { create(:adjustment, state: 'open') }
it "call some_method after close" do
adjustment.should_receive(:some_method)
adjustment.state = "closed"
end
end
failed with 失败了
1) Spree::Adjustment call some_method after close
Failure/Error: adjustment.should_receive(:some_method)
(#<Spree::Adjustment:0x0000000751a340>).some_method(any args)
expected: 1 time with any arguments
received: 0 times with any arguments
State machine transition don't work if you set state explicitly, like you do, with Adjustment#state=
method (in this case). 如果像使用
Adjustment#state=
方法那样显式设置状态(在这种情况下),则状态机转换将不起作用。 You should use events instead, for example: 您应该改用事件,例如:
adjustment.close
