This is a Scala 2.12 runner that fetches dependencies using sbt, and executes tests using scalatest.
In order to use this runner for your project, edit the codingame.yml file and add the following lines to your project:
runner:
name: codingame/sbt-scalatest-runner
version: 1.0.1-scala-2.12
We're using the following project:
.
├── build.sbt
├── codingame.yml
└── src
├── main
│ └── scala
│ └── example
│ └── Hello.scala
└── test
└── scala
└── example
└── HelloSpec.scala
In this example, the user is asked to write a hello world (in Hello.scala):
package example
object Hello extends Greeting with App {
println(greeting)
}
trait Greeting {
lazy val greeting: String = "hello"
}
In order to test the answer, the following unit test is created (in HelloSpec.scala):
package example
import org.scalatest._
class HelloSpec extends FlatSpec with Matchers {
"The Hello object" should "say hello" in {
Hello.greeting shouldEqual "hello"
}
}
The sbt build configuration is:
organization := "com.example"
version := "0.1.0-SNAPSHOT"
name := "Hello world"
scalaVersion := "2.12.0"
libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.0"
In the markdown file, the unit test can be called using:
@[Hello world!]({"stubs":["src/main/scala/example/Hello.scala"], "command":"example.HelloSpec"})
