REBOL [ title: "(R)EBOL (Un)it" date: 14-apr-06 file: %run.r Author: "Christophe 'REBOLtof' Coussement" Email: "reboltof-at-yahoo-dot-com" purpose: { RUn is a TestCase Framework wich allows the use of TestCases as defined by the eXtreme Programming development methodology and the test-driven development } usage: { Background information can be found into eXtreme Programming method. >> do %run.r 1. Submitted test file can be Unit or Suite >> run-test %unit-1.test >> run-test %suite-1.test 2. Output can be optionaly logged >> run-test/log %test_suite.test 3. A TestCase file contains: - optionaly a Setup function - one or more Developper Tests function(s) - optionaly a Teardown function 4. Each Developer Test can use one of the following test-functions: - assert (logic!) - assert-equal (any-value! any-value!) - assert-not-equal (any-value! any-value!) - assert-error (block!) 5. A TestSuite contains: One block! named 'test-suite and containing the TestCase files names or/and TestSuite file names } history: [ 1.9.3 [12-dec-07 {copy 'now and 'print so that they can be over-written in tests} "pwawood" ] 1.9.2 [14-mar-06 "cleanup for publishing" "cou"] 1.8.2 [27-mar-05 "add 'assert-error" "cou"] 1.7.2 [20-oct-04 {- 'pf_assert can take any-type! for evaluation - add 'pf_assert_not_equal (suggested by fvzn} "cou"] 1.6.2 [07-oct-04 {add /only ref to 'assert-equal} "cou"] 1.5.2 [20-sep-04 {- 'display made public (request from Coccinelle) - asserting object! into object! would fail => fixed (thanks again Coccinelle) - force the use of a %.test file (thanks Johnatemps)} "cou"] 1.4.2 [16-sep-04 {- assert-equal make object!
