Agile2012

The practices of unit testing and test-driven development (TDD) are mainstream for agile software development teams. While they also seem perfectly suited to the world of hardware development, where intense rigor is essential to avoiding the high costs of failure, unit testing and TDD are very rarely used. This talk proposes a new paradigm for achieving hardware quality where existing development and test practices are transformed through the addition of unit testing and TDD.
