23 ;;;; ============= NOTE =============
25 ;;;; This file is a quick-and-dirty adaptation of Aubrey's test suite
26 ;;;; to Guile's testing framework. As such, it's not as clean as one
27 ;;;; might hope. (In particular, it uses with-test-prefix oddly.)
29 ;;;; If you're looking for an example of a test suite to imitate, you
30 ;;;; might do better by looking at ports.test, which uses the
31 ;;;; (test-suite lib) functions much more idiomatically.
34 ;;;; "test.scm" Test correctness of scheme implementations.
35 ;;;; Author: Aubrey Jaffer
36 ;;;; Modified: Mikael Djurfeldt
37 ;;;; Removed tests which Guile deliberately
38 ;;;; won't pass. Made the the tests (test-cont), (test-sc4), and
39 ;;;; (test-delay) start to run automatically.
40 ;;;; Modified: Jim Blandy
41 ;;;; adapted to new Guile test suite framework
43 ;;; This includes examples from
44 ;;; William Clinger and Jonathan Rees, editors.
45 ;;; Revised^4 Report on the Algorithmic Language Scheme
46 ;;; and the IEEE specification.
48 ;;; The input tests read this file expecting it to be named
49 ;;; "test.scm", so you'll have to run it from the ice-9 source
50 ;;; directory, or copy this file elsewhere
51 ;;; Files `tmp1', `tmp2' and `tmp3' will be created in the course of running
52 ;;; these tests. You may need to delete them in order to run
53 ;;; "test.scm" more than once.
55 ;;; There are three optional tests:
56 ;;; (TEST-CONT) tests multiple returns from call-with-current-continuation
58 ;;; (TEST-SC4) tests procedures required by R4RS but not by IEEE
60 ;;; (TEST-DELAY) tests DELAY and FORCE, which are not required by
63 ;;; If you are testing a R3RS version which does not have `list?' do:
66 ;;; send corrections or additions to jaffer@ai.mit.edu or

69 ;; Note: The following two expressions are being read as part of the tests in
70 ;; section (6 10 2). Those tests expect that above the following two
71 ;; expressions there should be only one arbitrary s-expression (which is the
72 ;; define-module expression). Further, the two expressions should be written
73 ;; on one single line without a blank between them. If you change this, you
74 ;; will also have to change the corresponding tests in section (6 10 2).
