Interface Logger

All Known Implementing Classes:

Log4jLogger

public interface Logger

An logger is able to log runtime message to somewhere. For example, and text file. A log file allows user to monitor the testing status, debug the tests or do some thing for other purpose.
This interface is quite simple because Jetif is only a testing framework, while not a production framework. This logger interface should not be too complex.
