simple-tests

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.

The routines

simple-tests

[procedure] (simple-tests [sym])

documentation-procedure; returns the list of exported symbols if called with no symbol, otherwise the signature of that exported symbol sym.

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.

define-test

[syntax] (define-test (name . parameters) form . 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.

xpr:val

[syntax] (xpr:val xpr . xprs)

prints each xpr and its value in interpreted code only.

ppp

[syntax] (ppp xpr . xprs)

pretty-print with headline: alias to xpr:val

and?

[procedure] (and? xpr . xprs)

non-short-circuated and, which executes all side-effects.

pe

[procedure] (pe macro-code)

pretty-prints expanded macro-code.

*locations*

global dynamic variable controlling location of possibly nested tests.

*failures*

global variable collecting failure information

Example


(require-library simple-tests)
(import simple-tests)

(define-test (+?)
  (= (+ 1 2) 3)
  (= (+ 1 2 3) 6))

(define-test (*?)
  (= (* 1 2) 2)
  (= (* 1 2 3) 6))

(define-test (arithmetic?)
  (+?)
  (*?))

(compound-test (simple-tests)
  (arithmetic?))
