Rspec：be_succes（不是be_success）通过

Question

我在我的一项测试中注意到我的响应检查有错字，expect(response).to be_succes 而不是 expect(response).to be_success。测试通过了。为什么测试还是通过了？

response.succes? returns:

Failure/Error: response.succes?
     NoMethodError:
       undefined method `succes?' for #<ActionController::TestResponse:0x007fe6e22a2530>

Answer 1

我有一个chat with the guys at RSpec about this issue and it turns out that this is a somewhat intentional operation and is due to the present_tense_predicate and predicate methods in RSpec: https://github.com/rspec/rspec-expectations/blob/master/lib/rspec/matchers/built_in/be.rb#L248。

作为提出此问题的结果，已提议在 RSpec 4 中删除此问题：https://github.com/rspec/rspec-expectations/issues/935.

Rspec: be_succes(not be_success) passes
