自定义匹配器中的rspec mock should_receive

Question

我正在尝试使用RSpec模拟和should_receive自定义匹配器.我想捕获由should_receive匹配器返回正确值导致的错误,并导致它输出我的自定义失败消息.

怎么做？或许我应该改变我的做法？

Answer 1

答案是:

match do |obj|
  # do some setup and mocks here   
  begin
    RSpec::Mocks::verify  # run mock verifications
    true
  rescue RSpec::Mocks::MockExpectationError => e
    # here one can use #{e} to construct an error message
    false
  end
end
