java.lang.Object
- akka.testkit.EventFilter$

```
public class EventFilter$
extends java.lang.Object
```
Facilities for selectively filtering out expected events from logging so that you can keep your test run’s console output clean and do not miss real error messages.
'''Also have a look at the akka.testkit package object’s filterEvents and filterException methods.'''
The source filters do accept Class[_] arguments, matching any object which is an instance of the given class, e.g.
```
 EventFilter.info(source = classOf[MyActor]) // will match Info events from any MyActor instance
 
```
The message object will be converted to a string before matching ("null" if it is null).

Create a filter for Error events. Give up to one of start and pattern:


 EventFilter[MyException]()                                         // filter only on exception type
 EventFilter[MyException]("message")                                // filter on exactly matching message
 EventFilter[MyException](source = obj)                             // filter on event source
 EventFilter[MyException](start = "Expected")                       // filter on start of message
