This module exports some macros and procedures which help in debugging and testing. Most of the code is a straight-forward port of Peter Seibel's test suite in "Practical Common Lisp" to Chicken Scheme.
documentation-procedure; returns the list of exported symbols.
compound-test[syntax] (compound-test (name) test ...)
This is the obligatory wrapper around each individual test predicate. Runs each test (usually created by define-test) in sequence and prints the results of each as well as a combined result. Exits with 0 or 1 depending on success or failure.
simple-test[syntax] (simple-test (name) xpr ...)
runs each test expression, xpr, and prints success or failure as well as a summary, all prefixed with name. This macro is deprecated. Use compound-test instead.
define-test[syntax] (define-test (name . parameters) . forms)
creates a test predicate, (name . parameters), to be called within compound-test. That predicate will test and report the results of all of its form arguments.
check[syntax] (check xpr . xprs)
returns a unary procedure with location argument, which checks each of its xpr arguments and reports it.
xpr:val[syntax] (xpr:val xpr ...)
prints each xpr and its value in interpreted code.
and?[syntax] (and? xpr . xprs)
non-short-circuated and, which executes all side-effects.
pe[procedure] (pe macro-code)
pretty-prints expanded macro-code.
group-on-cdrs[procedure] (group-on-cdrs alist)
group an associated list into sublists with equal cdrs. To be used for failure reporting in compound-test.
global dynamic variable controlling location of possibly nested tests.
global variable collecting failure information
(use simple-tests) (define-test (+?) (check (= (+ 1 2) 3) (= (+ 1 2 3) 6))) (define-test (*?) (check (= (* 1 2) 2) (= (* 1 2 3) 6))) (define-test (arithmetic?) (+?) (*?)) (compound-test (simple-tests) (arithmetic?))
