Code re-use in Speclj

[Karsten Schmidt]

Hi,

I've been getting quite excited about integrating Speclj via its
auto-runner into my mixed CLJ/CLJS Org-mode/Babel setup, but now
feeling a bit lost how to go about wrapping a number of test
characteristics ("(it)" forms in speclj parlance) into re-usable
units. In the assertions below I'd like to parameterize the "+" calls
(i.e.. replace with other math ops), but the docs are pretty
slim/non-existent about how one could form modules/groups of such
parameterized tests. It doesn't seem to be possible to just wrap those
within a function:

(describe "blah"
(with a2 (vec2 1 2))
(with b2 (vec2 10 20))

;; FIXME how to group these as unit?
(it "a2 n m" (should= (+ @a2 @b2) (+ @a2 10 20)))
(it "a2 b2 m" (should= (+ (+ @a2 @b2) 20) (+ @a2 @b2 20)))
(it "a2 b2 b2" (should= (+ (+ @a2 @b2) @b2) (+ @a2 @b2 @b2)))
(it "a2 n b2" (should= (+ (+ @a2 10) @b2) (+ @a2 10 @b2))))

Any pointers please? Is it even possible? If not, isn't this a fairly
common use case?

Thanks!

My usual approach is to use a macro that expands to the appropriate (it) forms, or have a helper function that is called inside each (it)

"context" might be what you're looking for.

You can also use let instead of with. If you have multiple tests inside let wrap them in a context call.
