<TD> allows to set the Unit Test Framework log level in a range from a complete log, when all successful
tests are confirmed and all test suite messages are included, to an empty log when nothing is
logged a test output stream. Note that log levels are accumulating, in other words each log level
includes also all the information reported by less restrictive ones.</TD>
