<!--</lang>-->
Note the default behaviour, if set_test_verbosity() is not invoked, is no output and carry on as normal when all tests pass.<br>
Also note that set_test_pause() has no effect under pwa/p2js and the program will always carry on regardless of any failure, <br>
unless set_test_abort() other than TEST_QUIET is in force. You can of course invoke these routines in a platform-dependent <br>
way, for instance pause on the desktop but abort/stop completely in the browser, should that help.
{{out}}
TEST_QUIET with a failing test (no output or pause if no failing tests)<br>
