Team Eiffel

The CDD extension for EiffelStudio is an ETH Zurich project which adds support for unit testing to EiffelStudio 6.1. The current status is "beta 2", and it's released for Linux and Windows. Features include:

• visualization of test cases and their outcomes
• one button creation of manual test cases
• limiting of visible test cases using predefined filters and custom tags
• test case management through tags

Two further features are particularly interesting. Testing can be configured to occur in the background, and is described as "undisruptive to the developer". If an unexpected exception is thrown, a new test case is automatically created to reproduce the exception. Features like these can make the difference between a testing system that is useful as opposed to one that is merely usable.
