Sneak Peak: Unit Test Dependencies
Monday, September 7th, 2009
Here is a preview of a recently submitted paper on unit test dependencies. Besides the main contribution, a case-study on Lea’s automatic API migration and improved defect localization with JExample, a survey of over 2,500 open source projects is presented. We used the database of the Sourcerer code search engine (by Sushil Bajracharya and Joel Ossher) to analyse how unit testing frameworks are used and extended. As an appetizer: every second project has no test suite, every fourth test suite uses mock objects, and every tenth test suite uses third-party extensions.
The preview was created with Wordle, an idea that I owe to Tom Zimmermann.
