akka-test

This library is created to provide a reusable set of tests to be used in projects dependent on Akka libraries. For instance, to prevent the following "surprise" at runtime:

java.lang.IllegalStateException: Detected possible incompatible versions on the classpath. Please note that a given Akka HTTP version MUST be the same across all modules of Akka HTTP that you are using, e.g. if you use [10.1.11] all other modules that are released together MUST be of the same version. Make sure you're using a compatible set of libraries. Possibly conflicting versions [10.1.9, 10.1.11] in libraries [akka-http-spray-json:10.1.9, akka-parsing:10.1.11, akka-http-xml:10.1.11, akka-http:10.1.11, akka-http-core:10.1.11]

Version compatibility

Only the latest OSS Akka and Akka HTTP versions are supported:

• Akka: 2.6.x
• Akka-HTTP: 10.2.x

Since there is no OSS Akka-HTTP version published for Scala 3, submodules have different sets of supported major Scala versions:

• akka-test-actor: 2.12, 2.13, 3
• akka-test-http: 2.12, 2.13

For akka-actor 2.6.x

Tests:

• akka modules are of the same version

Usage

addSbtPlugin("com.evolution" % "sbt-artifactory-plugin" % "0.0.2")

libraryDependencies += "com.evolutiongaming" %% "akka-test-actor" % "0.2.0" % Test

And just drop this test into your project

import com.evolutiongaming.akkatest.AkkaActorSuite

class AkkaActorTest extends AkkaActorSuite

For akka-http 10.2.x

Tests:

• akka-http modules are of same version

Usage

Add dependency

addSbtPlugin("com.evolution" % "sbt-artifactory-plugin" % "0.0.2")

libraryDependencies += "com.evolutiongaming" %% "akka-test-http" % "0.2.0" % Test

And just drop this test into your project

import com.evolutiongaming.akkatest.AkkaHttpSuite

class AkkaHttpTest extends AkkaHttpSuite

Setup

addSbtPlugin("com.evolution" % "sbt-artifactory-plugin" % "0.0.2")

libraryDependencies += "com.evolutiongaming" %% "akka-test-actor" % "0.2.0"

libraryDependencies += "com.evolutiongaming" %% "akka-test-http" % "0.2.0"
