OpenEdge.ABLUnit package?

The latest ADE Source Code shipment from http://communities.progress.com/pcom/docs/DOC-107876#cf contains classes from an OpenEdge.ABLUnit package

src\ablunit\ABLUnitCore.p

src\ablunit\OpenEdge\ABLUnit\Assertions\Assert.cls

src\ablunit\OpenEdge\ABLUnit\Assertions\AssertEquals.i

src\ablunit\OpenEdge\ABLUnit\Assertions\AssertFalse.i

src\ablunit\OpenEdge\ABLUnit\Assertions\AssertionFailedException.cls

src\ablunit\OpenEdge\ABLUnit\Assertions\AssertTrue.i

src\ablunit\OpenEdge\ABLUnit\Reflection\AnnotationInfo.cls

src\ablunit\OpenEdge\ABLUnit\Reflection\ClassAnnotationInfo.cls

src\ablunit\OpenEdge\ABLUnit\Reflection\ClassInfo.cls

src\ablunit\OpenEdge\ABLUnit\Reflection\ProcedureAnnotationInfo.cls

src\ablunit\OpenEdge\ABLUnit\Reflection\TestInfo.cls

src\ablunit\OpenEdge\ABLUnit\Results\TestTestResult.cls

src\ablunit\OpenEdge\ABLUnit\Results\TestTypeResult.cls

src\ablunit\OpenEdge\ABLUnit\Runner\ABLRunner.cls

Was that intended to be shipped with the ADE Source? I didn't find those classes in the 11.2 shipment.

Is there any documentation available?

Is Progress planning to release more Unit Testing features soon?
