[英]Rspec test call method send reconfirmation instruction
我正在使用 Rspec 來測試用戶更改密碼時的情況,將發送郵件。 我想檢查是否只發送了 1 封郵件。 我不想使用Action::Mailer.deliveries
來檢查,而是想檢查是否調用了方法以及調用了多少。
在搜索時,我從 rspec mock 中找到了Test Spy
: https : //github.com/rspec/rspec-mocks#test-spies
describe 'PUT /email' do
include_context 'a user has signed in', { email: 'old-email@example.com', password: 'correct_password' }
context 'correct new email, correct password' do
before do
allow(user).to receive(:send_reconfirmation_instructions)
end
it do
should == 302
expect(user.reload.unconfirmed_email).to eq 'new-email@example.com'
expect(user).to receive(:send_reconfirmation_instructions).once
end
end
end
但我得到了錯誤:
Failure/Error: expect(user).to receive(:send_reconfirmation_instructions)
(#<User id: 1269, email: “old-email@example.com”, created_at: “2019-08-27 03:54:33", updated_at: “2019-08-27 03:54:33”...“>).send_reconfirmation_instructions(*(any args))
expected: 1 time with any arguments
received: 0 times with any arguments
send_reconfirmation_instructions
這個函數來自send_reconfirmation_instructions
: https : //github.com/plataformatec/devise/blob/master/lib/devise/models/confirmable.rb#L124-L130
我做了binding.pry
並且我確定這個函數內部的測試跳轉但是 rspec 仍然失敗。
編輯:我可以這樣寫:
describe 'PUT /email' do
include_context 'a user has signed in', { email: 'old-email@example.com', password: 'correct_password' }
context 'correct new email, correct password' do
before do
expect_any_instance_of(User).to receive(:send_reconfirmation_instructions).once
end
it do
should == 302
expect(user.reload.unconfirmed_email).to eq 'new-email@example.com'
# expect(user).to receive(:send_reconfirmation_instructions).once
end
end
end
但是我遇到了另一個錯誤:
Failure/Error:
(#<User user_id: 1418, email: “old-email@example.com”...“>).send_reconfirmation_instructions(#<User user_id: 1418, email: “old-email@example.com” ...“>)
expected: 1 time with any arguments
received: 2 times with arguments: (#<User user_id: 1418, email: “old-email@example.com”, id: 1323...“>)
您檢查用戶是否收到消息的行應為:
expect(user).to have_received(:send_reconfirmation_instructions).once
代替:
expect(user).to receive(:send_reconfirmation_instructions).once
前者你說expect(obj).to have_received(:msg)
要求你斷言消息被調用,正如你打算做的那樣。
另一方面,后者,你說expect(obj).to receive(:msg)
是一種在動作之前設置期望的方法,即代替allow(obj).to receive(:msg)
無需斷言它是在操作之后調用的。 規范運行后,它會自動斷言它是否被調用。
這解釋了您在指定時遇到的錯誤
expect(user).to receive(:send_reconfirmation_instructions).once
因為在該行之后沒有代碼將該消息發送給user
,該消息在規范之后得到驗證。
