[Development] Code coverage statistics online

[Harri Porten]

Hi!

We started publishing code coverage results of Qt 5 unit test runs as 
produced by our tool Squish Coco:

   http://download.froglogic.com/public/qt5-squishcoco-report/ (results)
   http://download.froglogic.com/public/effectively-testing-qt5-using-squishcoco/ (setup and example)

>From that link you can browse to the coverage data of libraries, functions 
and source files.

We chose a decision/coverage analysis method. In comparison to line 
coverage this is a bit harder to grasp and gives different numbers but for 
a developer it's the more useful. I plan to follow up with a study of a 
small number of exemplaric cases accompanied with suggested patches to 
tests and maybe code. And to make things easier to understand in the 
mostly-static HTML output we'll also improve the coloring of instrumented 
branches soon.

Provided that the cron job works the results will be updated daily. If 
anyone has an idea how this could be integrated more tightly with the 
automated Qt project test results please let us know. Caroline Chao was 
already using a predecessor of the tool for the same purpose within 
the Nokia build infrastructure btw.

Feedback of any kind is welcome.

Harri.
