ABAP Unit in Test-Driven Development

ABAP Unit provides excellent support for test-driven development in ABAP. Since ABAP Unit is integrated into the ABAP language:

• ABAP Unit testing is always available. You do not need to switch to a special operation mode or use a specially prepared server.
• You can run tests quickly and easily right from the development environment.
• You can navigate back and forth between a test class and the production code.
