Class LoggerTest

java.lang.Object

org.modeshape.common.logging.LoggerTest

public class LoggerTest
extends Object

Test the Logger class, ensuring that it uses Log4J appropriately. The Logger class uses the SLF4J generalized logging framework, which can sit on top of multiple logging frameworks, including Log4J. Therefore, this test assumes that SLF4J works correctly for all logging frameworks, then the Logger class can be tested by using it and checking the resulting Log4J output.

To ensure that the Log4J configuration used in the remaining tests (in src/test/resources/log4j.properties) does not interfere with this test, the underlying Log4J logger is obtained before each test and programmatically reconfigured and, after each test, is then restored to it's previous state. This reconfiguration involves identifying and removing all of the Log4J Appender on the tree of Log4J loggers, and substituting a special Appender that records the log messages in memory. During the test, this in-memory list of log messages is checked by the test case using standard assertions to verify the proper order and content of the log messages. After each of the tests, all of the original Adapters are restored to the appropriate Log4J loggers.
