Testing

You are viewing the documentation for the new actor APIs, to view the Akka Classic documentation, see Classic Testing.

Module info

The Akka dependencies are available from Akka’s library repository. To access them there, you need to configure the URL for this repository.

sbt

resolvers += "Akka library repository".at("https://repo.akka.io/maven")

Maven

<project>
  ...
  <repositories>
    <repository>
      <id>akka-repository</id>
      <name>Akka library repository</name>
      <url>https://repo.akka.io/maven</url>
    </repository>
  </repositories>
</project>

Gradle

repositories {
    mavenCentral()
    maven {
        url "https://repo.akka.io/maven"
    }
}

To use Actor TestKit add the module to your project:

sbt

val AkkaVersion = "2.9.7"
libraryDependencies += "com.typesafe.akka" %% "akka-actor-testkit-typed" % AkkaVersion % Test

Maven

<properties>
  <scala.binary.version>2.13</scala.binary.version>
</properties>
<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.typesafe.akka</groupId>
      <artifactId>akka-bom_${scala.binary.version}</artifactId>
      <version>2.9.7</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>
<dependencies>
  <dependency>
    <groupId>com.typesafe.akka</groupId>
    <artifactId>akka-actor-testkit-typed_${scala.binary.version}</artifactId>
    <scope>test</scope>
  </dependency>
</dependencies>

Gradle

def versions = [
  ScalaBinary: "2.13"
]
dependencies {
  implementation platform("com.typesafe.akka:akka-bom_${versions.ScalaBinary}:2.9.7")

  testImplementation "com.typesafe.akka:akka-actor-testkit-typed_${versions.ScalaBinary}"
}

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:
