I guess that there will be a way how to contribute new tests. (and
eventually read the existing ones). Until then here is a specimen FOR
test, which passes:
[
success: true
num: 0
for i 1 10 1 [
num: num + 1
success: i = num and success
]
10 = num and success
]
For an illustration here is a FOR test that fails:
; infinite loop tests
[
num: 0
for i b: [1] tail b 1 [
num: num + 1
if num > 2 [break]
]
num <= 2
]
This is a LOOP test inspired by Tim:
[
success: true
loop -1 [success: false]
success
]
-L
