Module info

To use Actor TestKit add the module to your project:

sbt
val PekkoVersion = "1.0.3"
libraryDependencies += "org.apache.pekko" %% "pekko-actor-testkit-typed" % PekkoVersion % Test
Maven
<properties>
  <scala.binary.version>2.13</scala.binary.version>
</properties>
<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>org.apache.pekko</groupId>
      <artifactId>pekko-bom_${scala.binary.version}</artifactId>
      <version>1.0.3</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>
<dependencies>
  <dependency>
    <groupId>org.apache.pekko</groupId>
    <artifactId>pekko-actor-testkit-typed_${scala.binary.version}</artifactId>
    <scope>test</scope>
  </dependency>
</dependencies>
Gradle
def versions = [
  ScalaBinary: "2.13"
]
dependencies {
  implementation platform("org.apache.pekko:pekko-bom_${versions.ScalaBinary}:1.0.3")

  testImplementation "org.apache.pekko:pekko-actor-testkit-typed_${versions.ScalaBinary}"
}

We recommend using Pekko TestKit with ScalaTest:

sbt
libraryDependencies += "org.scalatest" %% "scalatest" % "3.2.14" % Test
Maven
<properties>
  <scala.binary.version>2.13</scala.binary.version>
</properties>
<dependencies>
  <dependency>
    <groupId>org.scalatest</groupId>
    <artifactId>scalatest_${scala.binary.version}</artifactId>
    <version>3.2.14</version>
    <scope>test</scope>
  </dependency>
</dependencies>
Gradle
def versions = [
  ScalaBinary: "2.13"
]
dependencies {
  testImplementation "org.scalatest:scalatest_${versions.ScalaBinary}:3.2.14"
}

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:
