CapturingAppender

java.lang.Object
- ch.qos.logback.core.spi.ContextAwareBase
- - ch.qos.logback.core.AppenderBase<ch.qos.logback.classic.spi.ILoggingEvent>
  - - akka.actor.testkit.typed.internal.CapturingAppender

All Implemented Interfaces:

ch.qos.logback.core.Appender<ch.qos.logback.classic.spi.ILoggingEvent>, ch.qos.logback.core.spi.ContextAware, ch.qos.logback.core.spi.FilterAttachable<ch.qos.logback.classic.spi.ILoggingEvent>, ch.qos.logback.core.spi.LifeCycle
```
public class CapturingAppender
extends ch.qos.logback.core.AppenderBase<ch.qos.logback.classic.spi.ILoggingEvent>
```
INTERNAL API
Logging from tests can be silenced by this appender. When there is a test failure the captured logging events are flushed to the appenders defined for the akka.actor.testkit.typed.internal.CapturingAppenderDelegate logger.
The flushing on test failure is handled by LogCapturing for ScalaTest and LogCapturing for JUnit.
Use configuration like the following the logback-test.xml:
```
     <appender name="CapturingAppender" class="akka.actor.testkit.typed.internal.CapturingAppender" />

     <logger name="akka.actor.testkit.typed.internal.CapturingAppenderDelegate" >
       <appender-ref ref="STDOUT"/>
     </logger>

     <root level="DEBUG">
         <appender-ref ref="CapturingAppender"/>
     </root>
 
```
