I'm trying to expect an error in an rspec test.
lambda {Participant.create!({:user_id => three.id, :match_id => match.id, :team => 1})}.should raise_error StandardError For now I'm just using StandardError to make sure it's working.
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: It clearly throws the error, but my test still fails.
Thoughts?

Use the allow method with the receive matcher on a test double or a real. object to tell the object to return a value (or values) in response to a given. message. Nothing happens if the message is never received.
Summary: RSpec's subject is a special variable that refers to the object being tested. Expectations can be set on it implicitly, which supports one-line examples. It is clear to the reader in some idiomatic cases, but is otherwise hard to understand and should be avoided.
Since some time, but at least in RSpec 2.5, it is possible to use
expect {raise 'boom'}.to raise_error(RuntimeError, /boom/) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
