Testing

test is a language keyword. You do not import it.

Testing helpers are regular std functions and must be imported explicitly.

(use std/string)
(use std/result [Result])
(use std/testing [assert_eq])

(test "string/length"
  (let? [_ (assert_eq (string/length "hello") 5)]
    (assert_eq (string/length "") 0)))

Notes:

• test declarations are only allowed in files under tests/
• let? short-circuits on Result, no bind import required
• (use std) does not import assert_eq into unqualified scope
