当代码不正确时，应引发错误

Question

我想在代码不正确时看到错误，但我看到此失败

失败/错误：引发身份验证错误

UserAuthenticator::AuthenticationError:
UserAuthenticator::AuthenticationError

---

以下代码来自user_authenticator_spec

需要"rails_helper">

describe UserAuthenticator do
describe '#perform' do
context 'when code is incorrect' do
it 'should raise an error' do
authenticator = described_class.new('sample_code')
expect(authenticator.perform).to raise_error(AuthenticationError)
expect(authenticator.user).to be_nil
end
end
end
end

---

以及以下来自user_authenticator的代码

class UserAuthenticator
class AuthenticationError < StandardError; end
attr_reader :user
def initialize(code)
end
def perform
raise AuthenticationError
end
end

Answer 1

我更改了此行代码

expect(authenticator.perform).to raise_error(AuthenticationError)

自

expect{ authenticator.perform }.to raise_error(UserAuthenticator::AuthenticationError)

这是工作！
