17 Lightweight testing

The library (vicare checks) aprovides a simple mechanism for testing Scheme programs. As a primitive example, the expression:

(check (+ 1 1) => 3)

evaluates the expression (+ 1 1) and compares the result with the expected result ‘3’ provided after the syntactic keyword ‘=>’. Then the outcome of this comparison is reported in human–readable form by printing a message of the form:

(+ 1 1)
 => 2
 ; *** failed ***
 ; expected result: 3

The library (vicare checks) is derived by SRFI-78; SRFI-78 lightweight testing, for details.
