Apache MRUnit 0.8.1-incubating has been released!

From the post:

We (the Apache MRUnit team) have just released Apache MRUnit 0.8.1-incubating. Apache MRUnit is an Apache Incubator project. MRUnit is a Java library that helps developers unit test Apache Hadoop MapReduce jobs. Unit testing is a technique for improving project quality and reducing overall costs by writing a small amount of code that can automatically verify the software you write performs as intended. This is considered a best practice in software development since it helps identify defects early, before they’re deployed to a production system.

The MRUnit project is actively looking for contributors, even ones brand new to the world of open source software. There are many ways to contribute: documentation, bug reports, blog articles, etc. If you are interested but have no idea where to start, please email brock at cloudera dot com. If you are an experienced open source contributor, the MRUnit wiki explains How you can Contribute.

Opportunity to contribute to unit testing for MapReduce jobs.

BTW, what would unit testing for topic maps, ontologies, data models look like?

I grabbed Developing High Quality Data Models (Matthew West) off the shelf and flipped to the index. No entry for “unit testing,” “testing,” “validation,” etc.

Would the Topic Maps Constraint Language be sufficient for topic maps following the TMDM? So that you could incrementally test the design of streams of data into a topic map?
