The old JUnit tests are still present, but "ant test" and "ant fulltest" default
to the (pending) ScalaTest ones. To run the ScalaTest tests with Cobertura, execute
the following:
ant -Dscalatest.libs=./lib -Dwith.cobertura=/usr/share/java/cobertura.jar fulltest
The scalatest.libs property must point to a directory containing scala-compiler.jar,
scala-library.jar and scalatest.jar.
