Class ErrorLogMuter

java.lang.Object
org.apache.solr.util.ErrorLogMuter
All Implemented Interfaces:
Closeable, AutoCloseable
public final class ErrorLogMuter extends Object implements Closeable, AutoCloseable
Helper code for "Muting" ERROR log messages that you expect as a result of the things you are testing, so they aren't a distraction in test logs. Example usage... try (ErrorLogMuter errors = ErrorLogMuter.substring("nullfirst")) { assertQEx( "invalid query format", req( "q","id_i:1000", "sort", "nullfirst" ), 400 ); assertEquals(1, errors.getCount()); }

ERROR messages are considered a match if their input matches either the message String, or the toString of an included Throwable, or any of the recursive Throwable.getCause()es of an included Throwable.

Matching ERROR messages are "muted" by filtering them out of the ROOT logger. Any Appenders attached to more specific Loggers may still include these "muted" ERRROR messages.
