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.
- simple-tests #!optional symprocedure
documentation-procedure; returns the list of exported symbols if called with no symbol, otherwise the signature of that exported symbol sym.
- (compound-test (name) test ...)syntax
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 (name) xpr ...)syntax
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 (name . parameters) . forms)syntax
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 xpr . xprs)syntax
returns a unary procedure with location argument, which checks each of its xpr arguments and reports it.
- (xpr:val xpr . xprs)syntax
prints each xpr and its value in interpreted code only.
- (and? xpr . xprs)syntax
non-short-circuated and, which executes all side-effects.
- pe macro-codeprocedure
pretty-prints expanded macro-code.
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?) (check (x?) (*?))) (compound-test (simple-tests) (arithmetic?))
