To manage the testing output stream the Unit Test Framework uses a singleton class unit_test_log. This class is responsible for managing and formatting testing log. There two formats supported for testing log: human readable format and XML format. In most cases you do not need to use this class interface directly. The framework provides a simple way to set the log level and log format from outside of the test program. For more details and for the list of acceptable values see the Framework parameters.
There is only one instance if this class automatically created by the framework at test startup. To access it use method unit_test_log::instance().
