Passing additional arguments to tests with ScalaTest

In scalatest, we can use configMap to pass command parameters.

There is an example with using configMap:

import org.scalatest.{ConfigMap, fixture}

class TestSuite extends fixture.Suite with fixture.ConfigMapFixture{
  def testConfigMap(configMap: Map[String, Any]) {
    println(configMap.get("foo"))
    assert(configMap.get("foo").isDefined)
  }
}

object Test {
  def main(args: Array[String]): Unit = {
    (new TestSuite).execute(configMap = ConfigMap.apply(("foo","bar")))
  }
}

also we can run test with command line parameters:

scala -classpath scalatest-<version>.jar org.scalatest.tools.Runner -R compiled_tests -Dfoo=bar

scalatest runner ConfigMapFixture Test

I found interesting trait BeforeAndAfterAllConfigMap. This one has beforeAll method with a parameter configMap: ConfigMap. So here is my solution:

class Test extends FunSuite with BeforeAndAfterAllConfigMap {

  override def beforeAll(configMap: ConfigMap) = {
    //here will be some stuff and all args are available in configMap
  }

  test("Some test") {
    val arg = // here I want to get an argument which I want to pass. Something like args("arg_name")
    println(arg)
    assert(2 == 2)
  }
}
