[erlang-questions] common test hiding errors?

[Joel Reymont]

The following is what I see in logs/raw.log.

I know the game has crashed because the players are leaving and because showdown:winners did not return.

    =ERROR REPORT==== 9-Aug-2011::22:59:35 ===
    sitgo.erl:60 <0.258.0> hands ranked(<0.258.0>) call showdown:winners([{hand,<0.259.0>,1,[259,771],0,10,none,0}],[{0,[]}])
    
    =ERROR REPORT==== 9-Aug-2011::22:59:35 ===
    observer.erl:201 <0.275.0> Game 1: LEAVE -> 5
    (<0.258.0>) call showdown:winners([{hand,<0.259.0>,1,[259,771],0,10,none,0}],[{0,[]}],[])
    (<0.258.0>) call showdown:'-winners/3-fun-0-'({hand,<0.259.0>,1,[259,771],0,10,none,0},[])
    
    =ERROR REPORT==== 9-Aug-2011::22:59:35 ===
    observer.erl:201 <0.275.0> Game 1: LEAVE -> 4
    
    =ERROR REPORT==== 9-Aug-2011::22:59:35 ===
    observer.erl:201 <0.275.0> Game 1: LEAVE -> 3

Invoking showdown:winners at the Erlang prompt gives me an error.

    Eshell V5.8.4  (abort with ^G)
    1> showdown:winners([{hand,self(),1,[259,771],0,10,none,0}],[{0,[]}]).  
    ** exception error: no function clause matching 
                        gb_trees:is_defined(<0.31.0>,[])
         in function  lists:'-filter/2-lc$^0/1-0-'/2
         in call from showdown:winners/3

How do I make Common Test show me this error during testing?

	Thanks, Joel
