What is the CDD extension for EiffelStudio?

The Contract Driven Development (CDD) Extension to EiffelStudio. CDD provides full unit test integration into EiffelStudio. Here are some of its features:

  • Automated extraction of test cases from failures
    • For every exception thrown a new test case is created
  • Visualization of test cases and their outcomes
  • One button creation of manual test cases
  • Automated execution of test cases in the background
  • Limit visible test cases via predefined filters and custom tags
  • Testing occurs in the background and is completely undisruptive for the developer

If you have questions, feedback, or would like to report a bug please visit the [CDD forum]

Stefans Master Plan

  • MA Start ca 17.12.2007
  • MA End ca 17.6.2008
  • Testing the tester
    • System level test for CDD (incl. framework)
    • Recreating existing unit test suite with CDD
    • Large scale validation of CDD
      • Info 4 and/or Software Engineering
      • Questions
        • Does testing (manual/extracted) increase developer productivity?
        • How many tests do ppl end up with (manual/extracted)?
        • ...


Things we need from estudio

  • Invariants should be checked during debugging equally to pre- and post conditions (they could also be visualised in the flat view the same way like pre- and post conditions are)
  • The information whether some call is a creation call or a normal routine call (Not sure if this is really necessary, what if we assume every call to some creation procedure is always a creation call?)
  • Support for multiple open targets
