Testing Utility Functions

[Willard Hagen]

I am trying to test the utility functions and I am having a hard time coming up with test cases for them.

[Jay McCarthy]

Which ones?

I don't know what "both" means. Are you talking about take-while and
build-infinite-list?

The assignment page gives you two examples. Try those and then make more.

The second one gives you a specification. You can plug in any f and i,
and it's a valid test.

The first one doesn't give as much detail, but I hope that you
understand what filter is supposed to do and how this is related. If
you have specific questions, I'm happy to answer them.
