That is not how the reference implementation should work.
Typical output on Kawa:

$ ../bin/kawa  "./lib-test.scm"
%%%% Starting test libs  (Writing full log to "libs.log")
# of expected passes      269
# of expected failures    9

This is using the default test-runner, which writes a summary to standard output
(including 1 line for each unexpected failure or pass), and a detailed log to a file:

Kawa also has another test framework, which is useful for
short simple tests:  The file is just an executable module,
with expected output in comments:

(let ((x ::int 1))
   (set! x 0)
   (try-finally
    (if x (display "x is true")
        (display "x is not true"))
    (format #t "~%finally-clause executed~%")))
;; Output: x is true
;; Output: finally-clause executed

Comments can use plain text or regexps, specify error messages,
and compiler options.  This format is convenient for simple
regression tests, but matching error messages is likely
to be implementation-specific.

(Kawa also has another pre-srfi-64 test framework, but that
is not used for new tests.)

For a portable testing framework, I recommend srfi 64.
The reference implementation is a bit complicated because
it has a lot of bells and whistles, partly for the sake
of the detailed log written to the log file.
However, a minimal implementation that does not support
custom test runners would be quite simple.
