Today Artima released ScalaTest 1.5 for Scala 2.8.1. This release includes quite a few enhancements, including enhanced support for property-based testing; two new style traits, PropSpec and FreeSpec; nested, specification-style output for all styles; and many other enhancements.

You can download a zip file here:

Or grab it from scala-tools.org via:

group id: org.scalatest
artifact id: scalatest_2.8.1
version: 1.5

Or sbt:

val scalatest = "org.scalatest" % "scalatest_2.8.1" % "1.5"

No existing source code should break with this release, other than possibly through features that had been deprecated for several releases (most were deprecated in ScalaTest 1.0) that were removed in 1.5. Users will need to recompile their tests, but should not need to make any other changes to upgrade (though it might be a good idea to fix any deprecation warnings prior to upgrading.)

The enhancements released as 1.5 for Scala 2.8.1 are currently available for Scala 2.9.0 only through ScalaTest 1.6-SNAPSHOT. A release candidate for ScalaTest 1.6 should be published very soon.
