Scala example source code file (JavapTest.scala)

This example Scala source code file (JavapTest.scala) is included in my "Source Code Warehouse" project. The intent of this project is to help you more easily find Scala source code examples by using tags.

All credit for the original source code belongs to scala-lang.org; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

The JavapTest.scala Scala example source code

package scala.tools.partest

import scala.util.{Try,Success,Failure}
import java.lang.System.{out => sysout}

/** A trait for testing repl's javap command
 *  or possibly examining its output.
 */
abstract class JavapTest extends ReplTest {

  /** Your Assertion Here, whatever you want to bejahen.
   *  Assertions must be satisfied by all flavors of javap
   *  and should not be fragile with respect to compiler output.
   */
  def yah(res: Seq[String]): Boolean

  def baddies = List(":javap unavailable", ":javap not yet working")

  // give it a pass if javap is broken
  override def show() = try {
    val res = eval().toSeq
    val unsupported = res exists (s => baddies exists (s contains _))
    assert ((unsupported || yah(res)), res.mkString("","\n","\n"))
  } catch { case ae: AssertionError => ae.printStackTrace(sysout) }
}
