Testcontainers-scala

Scala wrapper for testcontainers-java that allows using docker containers for functional/integration/unit testing.

TestContainers is a Java 8 library that supports JUnit tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.

Setup

For scalatest users:

libraryDependencies += "com.dimafeng" %% "testcontainers-scala-scalatest" % testcontainersScalaVersion % "test"

For MUnit users:

libraryDependencies += "com.dimafeng" %% "testcontainers-scala-munit" % testcontainersScalaVersion % "test"

Requirements

Quick Start

First of all, let's add scalatest and MySQL testcontainers modules in the build.sbt file to play with:

libraryDependencies ++= Seq(
  "com.dimafeng" %% "testcontainers-scala-scalatest" % testcontainersScalaVersion % "test",
  "com.dimafeng" %% "testcontainers-scala-mysql" % testcontainersScalaVersion % "test",
)

Next, add the following line to run tests in a separate JVM from sbt. This allows for graceful shutdown of containers once the tests have finished running.

Test / fork := true,

There are two ScalaTest aware traits:

  • ForEachTestContainer starts a new container(s) before each test case and then stops and removes it.
  • ForAllTestContainer starts and stops a container only once for all test cases within the spec.

To start using it, you just need to extend one of those traits and override a container val as follows:

import com.dimafeng.testcontainers.{ForAllTestContainer, MySQLContainer}

class MysqlSpec extends AnyFlatSpec with ForAllTestContainer {

  override val container: MySQLContainer = MySQLContainer()

  it should "do something" in {
    Class.forName(container.driverClassName)
    val connection = DriverManager.getConnection(container.jdbcUrl, container.username, container.password)
    ...
  }
}

Be sure to override container with a val not a def, otherwise you will start a new container each time you call container and this is likely to fail your tests.

This spec has a clean mysql database instance for each of its test cases.

import org.testcontainers.containers.MySQLContainer

class MysqlSpec extends AnyFlatSpec with ForAllTestContainer {

    override val container: MySQLContainer = MySQLContainer()

    it should "do something" in {
      ...
    }

    it should "do something 2" in {
      ...
    }
}

This spec starts one container and both tests share the container's state.

Most of available container classes allow you to provide custom image name or version instead of default one set in the library.

In order to provide custom image name you need to pass DockerImageName object.

override val container: MongoDBContainer = MongoDBContainer(DockerImageName.parse("mongo:4.0.10"))

Starting from testcontainers-java 1.15.0 container classes execute image compatibility checks during initialization (for more details, see this pull request). If you want to use custom image that is compatible with selected container class implementation, it must be explicitly marked as compatible with default image.

override val container: MongoDBContainer = MongoDBContainer(DockerImageName.parse("myregistry/mongo:4.0.10").asCompatibleSubstituteFor("mongo"))

Providing custom image name as String is currently deprecated. Implicit conversion method is available in ScalaTest and MUnit traits.

class MongoSpec extends AnyFlatSpec with ForAllTestContainer {
    //deprecated implicit conversion
    override val container: MongoDBContainer = MongoDBContainer("mongo:4.0.10")
}

Modules

Testcontainers-scala is modular. All modules has the same version. To depend on some module put this into your build.sbt file:

libraryDependencies += "com.dimafeng" %% moduleName % testcontainersScalaVersion % "test"

Here is the full list of the currently available modules:

  • testcontainers-scala-core — core module. It contains some basic building blocks of the library and no integration with any test frameworks. You probably will not use it directly, because all other modules depend on it.
  • testcontainers-scala-scalatest — Scalatest integration module.
  • testcontainers-scala-munit — MUnit integration module.
  • testcontainers-scala-scalatest-selenium — module to use the Selenium container with the Scalatest.
  • testcontainers-scala-mysql — module with the MySQL container.
  • testcontainers-scala-postgresql — module with the PostgreSQL container.
  • testcontainers-scala-cassandra — module with the Cassandra container.
  • testcontainers-scala-kafka — module with the Kafka container.
  • testcontainers-scala-vault — module with the Vault container.
  • testcontainers-scala-oracle-xe — module with the Oracle container.
  • testcontainers-scala-neo4j — module with the Neo4J server container.
  • testcontainers-scala-mssqlserver — module with the MsSQL server container.
  • testcontainers-scala-clickhouse — module with the ClickHouse container.
  • testcontainers-scala-cockroachdb — module with the CockroachDB container.
  • testcontainers-scala-couchbase — module with the Couchbase container.
  • testcontainers-scala-db2 — module with the DB2 container.
  • testcontainers-scala-dynalite — module with the Dynalite container.
  • testcontainers-scala-elasticsearch — module with the Elastic search container.
  • testcontainers-scala-influxdb — module with the InfluxDB container.
  • testcontainers-scala-localstack — module with the Localstack container.
  • testcontainers-scala-localstack-v2 — module with the Localstack V2 container.
  • testcontainers-scala-mariadb — module with the MariaDB container.
  • testcontainers-scala-mockserver — module with the MockServer container.
  • testcontainers-scala-nginx — module with the Nginx container.
  • testcontainers-scala-pulsar — module with the Pulsar container.
  • testcontainers-scala-rabbitmq — module with the RabbitMQ container.
  • testcontainers-scala-toxiproxy — module with the ToxiProxy container.
  • testcontainers-scala-orientdb — module with the OrientDB container.
  • testcontainers-scala-presto — module with the Presto container.
  • testcontainers-scala-trino — module with the Trino container.
  • testcontainers-scala-mongodb — module with the MongoDB container.
  • testcontainers-scala-solr — module with the Solr container.

Most of the modules are just proxies to the testcontainers-java modules and behave exactly like java containers. You can find documentation about them in the testcontainers-java docs pages.

Container types

Generic Container

The most flexible but less convenient container type is GenericContainer. This container allows to launch any docker image with custom configuration.

class GenericContainerSpec extends AnyFlatSpec with ForAllTestContainer {
  override val container: GenericContainer = GenericContainer("nginx:latest",
    exposedPorts = Seq(80),
    waitStrategy = Wait.forHttp("/")
  )

  "GenericContainer" should "start nginx and expose 80 port" in {
    assert(Source.fromInputStream(
      new URL(s"http://${container.containerIpAddress}:${container.mappedPort(80)}/").openConnection().getInputStream
    ).mkString.contains("If you see this page, the nginx web server is successfully installed"))
  }
}

Docker Compose

class ComposeSpec extends AnyFlatSpec with ForAllTestContainer {
  override val container: DockerComposeContainer = DockerComposeContainer(new File("src/test/resources/docker-compose.yml"), exposedServices = Seq(ExposedService("redis_1", 6379)))

  "DockerComposeContainer" should "retrieve non-0 port for any of services" in {
    assert(container.getServicePort("redis_1", 6379) > 0)
  }
}

Selenium

Before you can use this type of containers, you need to add the following dependencies to your project:

"com.dimafeng" %% "testcontainers-scala-scalatest-selenium" % testcontainersScalaVersion % "test"

Now you can write a test in this way:

class SeleniumSpec extends AnyFlatSpec with SeleniumTestContainerSuite with WebBrowser {
  override def desiredCapabilities = DesiredCapabilities.chrome()

  "Browser" should "show google" in {
      go to "http://google.com"
  }
}

In this case, you'll obtain a clean instance of browser (firefox/chrome) within container to which a test will connect via remote-driver. See Webdriver Containers for more details.

Mysql

Requires you to add this dependency:

"com.dimafeng" %% "testcontainers-scala-mysql" % testcontainersScalaVersion % "test"
class MysqlSpec extends AnyFlatSpec with ForAllTestContainer {

  override val container: MySQLContainer = MySQLContainer()

  "Mysql container" should "be started" in {
    Class.forName(container.driverClassName)
    val connection = DriverManager.getConnection(container.jdbcUrl, container.username, container.password)
      ...
  }
}

The container can also be customized using the constructor parameters, this snippet will initialize a docker container from a specific docker image, with a specific schema name and specific username/password

class MysqlSpec extends AnyFlatSpec with ForAllTestContainer {

  override val container: MySQLContainer = MySQLContainer(mysqlImageVersion = DockerImageName.parse("mysql:5.7.18"),
                                          databaseName = "testcontainer-scala",
                                          username = "scala",
                                          password = "scala")

  "Mysql container" should "be started" in {
    Class.forName(container.driverClassName)
    val connection = DriverManager.getConnection(container.jdbcUrl, container.username, container.password)
      ...
  }
}

PostgreSQL

Requires you to add this dependency:

"com.dimafeng" %% "testcontainers-scala-postgresql" % testcontainersScalaVersion % "test"
class PostgresqlSpec extends AnyFlatSpec with ForAllTestContainer  {

  override val container: PostgreSQLContainer = PostgreSQLContainer()

  "PostgreSQL container" should "be started" in {
    Class.forName(container.driverClassName)
    val connection = DriverManager.getConnection(container.jdbcUrl, container.username, container.password)
      ...
  }
}

Multiple Containers

If you need to test more than one container in your test, you could use MultipleContainers for that. Just define your containers and pass them to the MultipleContainers constructor:

val mySqlContainer = MySQLContainer()
val genericContainer = GenericContainer(...)

override val container: MultipleContainers = MultipleContainers(mySqlContainer, genericContainer)

Dependent containers

If configuration of one container depends on runtime state of another one, you should define your containers as lazy:

lazy val container1 = Container1()
lazy val container2 = Container2(container1.port)

override val container: MultipleContainers = MultipleContainers(container1, container2)

Fixed Host Port Containers

This container will allow you to map container ports to statically defined ports on the docker host.

...
val container = FixedHostPortGenericContainer("nginx:latest",
    waitStrategy = Wait.forHttp("/"),
    exposedHostPort = 8090,
    exposedContainerPort = 80
  )

Custom configuration of inner containers

All container types have constructor methods with most popular parameters. In case you're missing some custom option from testcontainers-java, there is a method that provides an elegant way to tune the nested container. It's not recommended to access inner container directly.

override val container: MySQLContainer = MySQLContainer().configure { c =>
    c.withNetwork(...)
    c.withStartupAttempts(...)
  }

Start/Stop hooks

If you want to execute your code after container start or before container stop you can override afterStart() and beforeStop() methods.

class MysqlSpec extends AnyFlatSpec with ForAllTestContainer {

  ...

  override def beforeStop(): Unit = {
    // your code
  }

  override def afterStart(): Unit = {
    // your code
  }
}

New API

Starting from 0.34.0 version testcontainers-scala provides the new API. The main motivation points are in the pull request.

This API is experimental and may change!

Container and ContainerDef

Docker containers are represented through the two different entities:

  1. ContainerDef — it's container definition. ContainerDef describes, how to build a container. You can think about it like about a container constructor, or dockerfile description. Usually, ContainerDef receives some parameters. ContainerDef has a start() method. It returns a started Container.
  2. Container — it's a started container. You can interact with it through its methods. For example, in the case of MySQLContainer you can get it's JDBC URL with jdbcUrl method. Container is the main entity for using inside tests.

Scalatest usage

You can use one of the four traits:

  1. TestContainerForAll — will start a single container before all tests and stop after all tests.
  2. TestContainerForEach — will start a single container before each test and stop after each test.
  3. TestContainersForAll — will start multiple containers before all tests and stop after all tests.
  4. TestContainersForEach — will start multiple containers before each test and stop after each test.

Single container in tests

If you want to use a single container in your test:

class MysqlSpec extends AnyFlatSpec with TestContainerForAll {

  // You need to override `containerDef` with needed container definition
  override val containerDef = MySQLContainer.Def()

  // To use containers in tests you need to use `withContainers` function
  it should "test" in withContainers { mysqlContainer =>
    // Inside your test body you can do with your container whatever you want to
    assert(mysqlContainer.jdbcUrl.nonEmpty)
  }
}

Usage of TestContainerForEach is not different from the example above.

Multiple containers in tests

If you want to use multiple containers in your test:

class ExampleSpec extends AnyFlatSpec with TestContainersForAll {

  // First of all, you need to declare, which containers you want to use
  override type Containers = MySQLContainer and PostgreSQLContainer and DockerComposeContainer

  // After that, you need to describe, how you want to start them,
  // In this method you can use any intermediate logic.
  // You can pass parameters between containers, for example.
  override def startContainers(): Containers = {
    val container1 = MySQLContainer.Def().start()
    val container2 = PostgreSQLContainer.Def().start()
    val container3 = DockerComposeContainer.Def(ComposeFile(Left(new File("docker-compose.yml")))).start()
    container1 and container2 and container3
  }
  
  // `withContainers` function supports multiple containers:
  it should "test" in withContainers { case mysqlContainer and pgContainer and dcContainer =>
    // Inside your test body you can do with your containers whatever you want to
    assert(mysqlContainer.jdbcUrl.nonEmpty && pgContainer.jdbcUrl.nonEmpty)
  }
  
}

Usage of TestContainersForEach is not different from the example above.

GenericContainer usage

To create a custom container, which is not built-in in the library, you need to use GenericContainer.

For example, you want to create a custom nginx container:

class NginxContainer(port: Int, underlying: GenericContainer) extends GenericContainer(underlying) {
  // you can add any methods or fields inside your container's body
  def rootUrl: String = s"http://$containerIpAddress:${mappedPort(port)}/"
}
object NginxContainer {

  // In the container definition you need to describe, how your container will be constructed:
  case class Def(port: Int) extends GenericContainer.Def[NginxContainer](
    new NginxContainer(port, GenericContainer(
      dockerImage = "nginx:latest",
      exposedPorts = Seq(port),
      waitStrategy = Wait.forHttp("/")
    ))
  )
}

However, if you don't want to create a custom container, you can use GenericContainer directly while overriding containerDef:

override val containerDef = GenericContainer.Def("nginx:latest",
  exposedPorts = Seq(80),
  waitStrategy = Wait.forHttp("/")
)

Migration from the classic API

  1. If you have custom containers created with the GenericContainer, add ContainerDef in the companion like this:
    object MyCustomContainer {
      case class Def(/*constructor params here*/) extends GenericContainer.Def[MyCustomContainer](
        new MyCustomContainer(/*constructor params here*/)
      )
    }
  2. If you are using ForEachTestContainer:
    1. If your test contains only one container, replace ForEachTestContainer with TestContainerForEach
    2. If your test contains multiple containers, replace ForEachTestContainer with TestContainersForEach
  3. If you are using ForAllTestContainer:
    1. If your test contains only one container, replace ForAllTestContainer with TestContainerForAll
    2. If your test contains multiple containers, replace ForAllTestContainer with TestContainersForAll
  4. Fix all compilation errors using compiler messages and examples above.

MUnit usage

Similarly to Scalatest, you can use one of the four traits:

  1. TestContainerForAll — will start a single container before all tests and stop after all tests.
  2. TestContainerForEach — will start a single container before each test and stop after each test.
  3. TestContainersForAll — will start multiple containers before all tests and stop after all tests.
  4. TestContainersForEach — will start multiple containers before each test and stop after each test.

Single container in tests

If you want to use a single container for all tests in your suite:

class MysqlSpec extends FunSuite with TestContainerForAll {

  // You need to override `containerDef` with needed container definition
  override val containerDef = MySQLContainer.Def()

  // To use containers in tests you need to use `withContainers` function
  test("test case name") {
    withContainers { mysqlContainer =>
      // Inside your test body you can do with your container whatever you want to
      assert(mysqlContainer.jdbcUrl.nonEmpty)
    }
  }
}

If you want to use a single container for each test in your suite just use code above with TestContainerForEach trait instead of TestContainerForAll.

Multiple containers in tests

If you want to use multiple containers for all tests in your suite:

class ExampleSpec extends FunSuite with TestContainersForAll {

  // First of all, you need to declare, which containers you want to use
  override type Containers = MySQLContainer and PostgreSQLContainer and DockerComposeContainer

  // After that, you need to describe, how you want to start them,
  // In this method you can use any intermediate logic.
  // You can pass parameters between containers, for example.
  override def startContainers(): Containers = {
    val container1 = MySQLContainer.Def().start()
    val container2 = PostgreSQLContainer.Def().start()
    val container3 = DockerComposeContainer.Def(ComposeFile(Left(new File("docker-compose.yml")))).start()
    container1 and container2 and container3
  }

  // `withContainers` function supports multiple containers:
  test("test") {
    withContainers { case mysqlContainer and pgContainer and dcContainer =>
      // Inside your test body you can do with your containers whatever you want to
      assert(mysqlContainer.jdbcUrl.nonEmpty && pgContainer.jdbcUrl.nonEmpty)
    }
  }
}

If you want to use a single container for each test in your suite just use code above with TestContainersForEach trait instead of TestContainersForAll.

Start/Stop hooks

You have the option to override afterContainersStart and beforeContainersStop methods.

Example with single container
class MySpec extends AnyFlatSpec with TestContainerForAll {

  override val containerDef: ContainerDef =
    PostgreSQLContainer.Def(DockerImageName.parse("postgres:12"))

  override def afterContainersStart(container: Containers): Unit = {
    super.afterContainersStart(container)

    container match {
      case _: PostgreSQLContainer => println("your logic here")
    }
  }

  override def beforeContainersStop(container: Containers): Unit = {
    super.beforeContainersStop(container)

    container match {
      case _: PostgreSQLContainer => println("your logic here")
    }
  }

 it should "work" in withContainers { 
   case pgContainer: PostgreSQLContainer =>
     assert(pgContainer.jdbcUrl.nonEmpty) 
  }
}
Example with multiple containers
class MySpec extends AnyFlatSpec with TestContainersForAll {

  override type Containers = MySQLContainer and PostgreSQLContainer

  override def startContainers(): Containers = {
    val container1 = MySQLContainer.Def().start()
    val container2 = PostgreSQLContainer.Def().start()

    container1 and container2
  }

  override def afterContainersStart(containers: Containers): Unit = {
    super.afterContainersStart(containers)

    containers match {
      case mySqlContainer and pgContainer => println("your logic here")
    }
  }

  override def beforeContainersStop(containers: Containers): Unit = {
    super.beforeContainersStop(containers)

    containers match {
      case mySqlContainer and pgContainer => println("your logic here")
    }
  }

  it should "work" in withContainers {
    case mysqlContainer and pgContainer =>
      assert(mysqlContainer.jdbcUrl.nonEmpty && pgContainer.jdbcUrl.nonEmpty)
  }

}

Notes on MUnit usage

  • If you use *ForAll trait and override beforeAll() without calling super.beforeAll() your containers won't start.
  • If you use *ForAll trait and override afterAll() without calling super.afterAll() your containers won't stop.
  • If you use *ForEach trait and override beforeEach() without calling super.beforeEach() your containers won't start.
  • If you use *ForEach trait and override afterEach() without calling super.afterEach() your containers won't stop.
  • Currently, there is no way to retrieve test status in MUnit afterEach block, so afterTest hook will never contain an error.

    • The library is split into multiple modules. Every built-in container now has a separate module with all needed transitive dependencies, so you will not have to add them manually. More details are above, in the dedicated paragraph. Old module testcontainers-scala is still provided but will be eventually dropped in future. To migrate to the new modules remove testcontainers-scala dependency and add only needed dependencies from the modules list in the docs.
