How to increase default timeout for ScalaTestWithActorTestKit

问题

I have a test which constructs another event sourcing actor from inside message handler and this construction is taking more than 3 seconds. Below is current configuration, how can I increase default timeout?

  extends ScalaTestWithActorTestKit(
    ConfigFactory.parseString("""
    akka.persistence.testkit.events.serialize = off
    akka.actor.allow-java-serialization = on
    akka.test.single-expect-default = 999s
    """).withFallback(PersistenceTestKitPlugin.config).withFallback(ManualTime.config)

Here is the error message:

Timeout (3 seconds) during receiveMessage while waiting for message.
java.lang.AssertionError: Timeout (3 seconds) during receiveMessage while waiting for message.
