Hi, I have just started learning Haskell this semester, and I have some questions of things which puzzles me: 1. I would like to ask that how is it possible to set quickCheck test numbers to something else then the default 100 passes? I have found an article which says: deepCheck p = check (defaultConfig { configMaxTest = 10000}) p which I tried and it works at a home Ubuntu install but when I tried it at my university network, it says: Not in scope: `check' Not in scope: `defaultConfig' Not in scope: `configMaxTest' Isn't there a way of making quickCheck use a different number by using '==>' functions for example? Is quickCheck p = check (defaultConfig) p? 2. How could I print the result of a complex quickCheck generator? I mean if there is an error is says it, but what if I would like to generate just random expressions which quickCheck can do? Zsolt
