[plt-scheme] Re: [plt-edu] Why is testing not working?

1. Pasted into the definitions window:

(define (f x) 0)

(check-expect (f  5) 0)
(check-expect (f 10) 1)

2. Press Run

3. Result in interactions window:

Welcome to DrScheme, version 4.1.2 [3m].
Language: Beginning Student with List Abbreviations; memory limit: 128
megabytes.

No failed test reported.
