Module info

To use Actor TestKit add the module to your project:

sbt

libraryDependencies += "com.typesafe.akka" %% "akka-actor-testkit-typed" % "2.6-SNAPSHOT" % Test

Maven

<dependency>
  <groupId>com.typesafe.akka</groupId>
  <artifactId>akka-actor-testkit-typed_2.12</artifactId>
  <version>2.6-SNAPSHOT</version>
  <scope>test</scope>
</dependency>

Gradle

dependencies {
  test group: 'com.typesafe.akka', name: 'akka-actor-testkit-typed_2.12', version: '2.6-SNAPSHOT'
}

We recommend using Akka TestKit with ScalaTest:

sbt

libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.7" % Test

Maven

<dependency>
  <groupId>org.scalatest</groupId>
  <artifactId>scalatest_2.12</artifactId>
  <version>3.0.7</version>
  <scope>test</scope>
</dependency>

Gradle

dependencies {
  test group: 'org.scalatest', name: 'scalatest_2.12', version: '3.0.7'
}

Introduction

Testing can either be done asynchronously using a real ActorSystemActorSystem or synchronously on the testing thread using the BehaviorTestKitBehaviorTestKit.

For testing logic in a BehaviorBehavior in isolation synchronous testing is preferred, but the features that can be tested are limited. For testing interactions between multiple actors a more realistic asynchronous test is preferred.

Those two testing approaches are described in:
