How to dump sinatra rack test exceptions to console? <p>While I develop, I would like to see sinatra app exceptions when running tests, cosider example:</p> <pre><code>require 'sinatra/base' class ExceptionWeb &lt; Sinatra::Base enable :raise_errors enable :dump_errors configure do enable :dump_errors end get "/" do raise "hell" "ok" end def self.bad_method raise "bad method" end end require 'rack/test' describe 'The Web interface' do include Rack::Test::Methods def app ExceptionWeb end it "should error out" do get "/" #puts last_response.errors #ExceptionWeb.bad_method #last_response.should be_ok end end </code></pre> <p>Following rspec code shows no exceptions at all, if I uncomment last_response, then I see something is wrong, but I don't see what was wrong.</p> <p>But calling <code>mad_method</code> shows me exception.</p> <p>And adding <code>puts last_response.errors</code> to every test doesn't look proper.</p> <p>I tried sinatra config options <code>raise_errors</code> and <code>dump_errors</code> but that doesn't help me much.</p> <p>Any ideas?</p>
