Vincent Massol, Technical Director of XWiki SAS, wrote an article about a recent experimentation with Descartes, a mutation engine for PIT, in the framework of the STAMP project. 

Here's an example of running Descartes on an XWiki module:

XWiki SAS is part of the STAMP research project and one domain of this research is improving configuration testing.

In this article, Vincent Massol, Technical Director of XWiki SAS, suggests a new architecture that should allow XWiki to be tested on various configurations, including various supported databases and versions, various Servlet containers and versions, and Various Browsers and versions.

I am extremely proud and happy that my talk on mutation testing got accepted as an early bird for EclipseCon Europe 2017.

We will talk a lot about software testing at the project quality day. In this talk, I will focus on qualitative evaluation of a unit test suite. Statement coverage is commonly used to quantify the quality of a test suite: it measures the ratio of source code statements that are executed at least once when running the test suite. However, statement coverage is known to be a rather weak quality indicator. For example, a test suite that covers 100% of the statements and that has absolutely no assertion is a very bad test suite, yet is considered of excellent quality according statement coverage.

Generating full coverage report for a multi-reactor project is a complex task.
Hopefully, Vincent Massol, XWiki CTO, provides a script with clear explanations for that need.
