Class TestLogger

java.lang.Object

uk.org.lidalia.slf4jtest.TestLogger

All Implemented Interfaces:

Logger

public class TestLogger
extends Object
implements Logger

Implementation of Logger which stores LoggingEvents in memory and provides methods to access and remove them in order to facilitate writing tests that assert particular logging calls were made.

LoggingEvents are stored in both an ThreadLocal and a normal List. The getLoggingEvents() and clear() methods reference the ThreadLocal events. The getAllLoggingEvents() and clearAll() methods reference all events logged on this Logger. This is in order to facilitate parallelising tests - tests that use the thread local methods can be parallelised.

By default all Levels are enabled. It is important to note that the conventional hierarchical notion of Levels, where info being enabled implies warn and error being enabled, is not a requirement of the SLF4J API, so the setEnabledLevels(ImmutableSet), setEnabledLevels(Level...), setEnabledLevelsForAllThreads(ImmutableSet), setEnabledLevelsForAllThreads(Level...) and the various isXxxxxEnabled() methods make no assumptions about this hierarchy. If you wish to use traditional hierarchical setups you may do so by passing the constants in ConventionalLevelHierarchy to setEnabledLevels(ImmutableSet) or setEnabledLevelsForAllThreads(ImmutableSet).

getEnabledLevels

public ImmutableSet<uk.org.lidalia.slf4jext.Level> getEnabledLevels()

Returns:

the set of levels enabled for this logger on this thread

setEnabledLevels

public void setEnabledLevels(ImmutableSet<uk.org.lidalia.slf4jext.Level> enabledLevels)

The conventional hierarchical notion of Levels, where info being enabled implies warn and error being enabled, is not a requirement of the SLF4J API, so all levels you wish to enable must be passed explicitly to this method. If you wish to use traditional hierarchical setups you may conveniently do so by using the constants in ConventionalLevelHierarchy

Parameters:

enabledLevels - levels which will be considered enabled for this logger IN THIS THREAD; does not affect enabled levels for this logger in other threads

setEnabledLevels

public void setEnabledLevels(uk.org.lidalia.slf4jext.Level... enabledLevels)

The conventional hierarchical notion of Levels, where info being enabled implies warn and error being enabled, is not a requirement of the SLF4J API, so all levels you wish to enable must be passed explicitly to this method. If you wish to use traditional hierarchical setups you may conveniently do so by passing the constants in ConventionalLevelHierarchy to setEnabledLevels(ImmutableSet)

Parameters:

enabledLevels - levels which will be considered enabled for this logger IN THIS THREAD; does not affect enabled levels for this logger in other threads

setEnabledLevelsForAllThreads

public void setEnabledLevelsForAllThreads(ImmutableSet<uk.org.lidalia.slf4jext.Level> enabledLevelsForAllThreads)

The conventional hierarchical notion of Levels, where info being enabled implies warn and error being enabled, is not a requirement of the SLF4J API, so all levels you wish to enable must be passed explicitly to this method. If you wish to use traditional hierarchical setups you may conveniently do so by using the constants in ConventionalLevelHierarchy

Parameters:

enabledLevelsForAllThreads - levels which will be considered enabled for this logger IN ALL THREADS

setEnabledLevelsForAllThreads

public void setEnabledLevelsForAllThreads(uk.org.lidalia.slf4jext.Level... enabledLevelsForAllThreads)

The conventional hierarchical notion of Levels, where info being enabled implies warn and error being enabled, is not a requirement of the SLF4J API, so all levels you wish to enable must be passed explicitly to this method. If you wish to use traditional hierarchical setups you may conveniently do so by passing the constants in ConventionalLevelHierarchy to setEnabledLevelsForAllThreads(ImmutableSet)

Parameters:

enabledLevelsForAllThreads - levels which will be considered enabled for this logger IN ALL THREADS
