Log formats

Test log output
HRF: Human readable log format
XML log format
JUNIT log format

The Unit Test Framework supports several log formats:

HRF: human readable format
XML: an machine interpretable log format
JUNIT: a standardized log format understandable by automated tools such as Continuous Builds

Design

The following functionalities are supported by the logging framework:

each logger manages its own log level. The rationale is that some log format are meant for automated processing, and by design need to carry all the information that will later be digested by a visualization tool.
several log format may be active at the same time. The rationale is that the user might want to see a non-exhaustive log in his terminal using a human friendly format, while having a detailed full log in a file with a format dedicated to automated processing.
each logger indicates its default output stream. some logger may prefer to output to one of the standard stream while other may prefer output to a file.

	Note
	The logger indicates the default output stream in case the default should be used.

Defaults

By default the active log level threshold is set to

"non fatal error messages" and the test log output is generated in human readable format.
"general information" for JUNIT log format

The active log level threshold and the output format can be configured at runtime during a test module invocation and at compile time from within a test module using the test log public interfaces. The behavior is logger specific though.
