Software testing is a important part of software development.

In earlier days testing of a software was typically done at the end of the development cycle. Since this is very late to uncover severe problems, today's approach relies heavily on test automation. An important part for this is testing individual pieces of the code (unit testing). Even more, with Test-Driven-Development (TDD) tests are written before implementing a part of the application.

Many actual programming languages ​​provide appropriate tools for automated test execution. The VBA programming language and the Code Editor (the VBE - Visual Basic Editor) unfortunately only contain rudimentary functionality to support testing of code (Debug.Print, Debug.Assert).

AccUnit now offers the possibility to run automated tests on MS Access. It uses the SimplyVBUnit, an Unit Testing Framework written in VB6.
