ruby-on-rails - rspec 测试中预计会出现错误

Question

我试图预期 rspec 测试中出现错误。

lambda {Participant.create!({:user_id => three.id, :match_id => match.id, :team => 1})}.should raise_error StandardError

现在我只是使用 StandardError 来确保它正常工作。

1) StandardError in 'Participant should never allow more participants than players'. 
   This game is already full.  Cannot add another player.
/home/josiah/Projects/Set-Match/app/models/participant.rb:12:in `do_not_exceed_player_count_in_match'
./spec/models/participant_spec.rb:24:

它显然抛出了错误，但我的测试仍然失败。

想法？

Answer 1

有一段时间了，但至少在 RSpec 2.5 中，可以使用

expect {raise 'boom'}.to raise_error(RuntimeError, /boom/)
