Play! framework: customize which tests are run

Question

I have a Play! 2 for Scala application, and I am using Specs2 for tests. I can run all tests with the test command, or a particular specification with test-on

Answer 1

You can also use without any change to your build

test-only * -- exclude integration

Tested in Play 2.1-RC3

Answer 2

First, following the specs2 guide one must add tags to the specifications, like this

class MySpec extends Specification with Tags {
  "My spec" should {
    "exclude this test" in {
      true
    } tag ("foo")

    "include this one" in {
      true
    }
  }
}

The command line arguments to include are documented here

Then one can selectively include or exclude test with

test-only MySpec -- exclude foo
test-only MySpec -- include foo

Answer 3

I'm using Play2.2, and there are 2 ways to do this depending on whether or not you are in the play console.

1. From the console type: test-only full.namespace.to.TestSpec
2. From the terminal type: test-only "full.namespace.to.TestSpec"

Answer 4

I came across this question while trying to figure out how to do something similar for ScalaTest with Play. SBT has detailed documentation on how to configure additional test configurations but these could use a bit of tweaking for Play.

Apart from the subtly different Project configuration I found that I wanted to crib a bunch of the test settings from PlaySettings. The following is running and generating an Intellij project with integration test sources in the "/it" directory. I may still be missing reporting and lifecycle hooks,

object BuildSettings {
  def testSettings = {
    // required for ScalaTest. See http://stackoverflow.com/questions/10362388/using-scalatest-in-a-playframework-project
    testOptions in Test := Nil
  }

  def itSettings = {
    // variously cribbed from https://github.com/playframework/Play20/blob/master/framework/src/sbt-plugin/src/main/scala/PlaySettings.scala
    sourceDirectory in IntegrationTest <<= baseDirectory / "it"
    scalaSource in Test <<= baseDirectory / "it"
    libraryDependencies += "play" %% "play-test" % play.core.PlayVersion.current % "it"
  }
}

object ApplicationBuild extends Build {
  val main = play.Project(
    appName,
    appVersion,
    Dependencies.dependencies)
    .configs( IntegrationTest )
    .settings(Dependencies.resolutionRepos)
    .settings(BuildSettings.testSettings)
    .settings(Defaults.itSettings : _*)
    .settings(BuildSettings.itSettings)
}

If you want to pass several arguments you can add several strings to one Test.Argument

testOptions in Test += Tests.Argument("include", "unit")

There are examples of this in the specs2 User Guide here and in the Play documentation there.
