Description Björn Michaelsen 2013-10-14 11:12:47 UTC
Writing unittests with coverage for all of LibreOffice might appear a daunting and insurmountable task. Given the vastness of the codebase it makes sense to focus on the areas of the codebase that historically have been hit most by regressions and are not already covered well by unittests.
There is a list of those areas at:


This EasyHack is to write unittests providing good coverage for these hotspots first, which should have the best benefit over cost and is much more limited in scope.

The regression hotspots can be cross compared with their respective test coverage:

I will start working on this. I will try to add unit tests for one of the area in the list. If someone could tell me a more specific area that needs unit tests that would be appreciated.

Re-evaluating the EasyHack in 2022

This task is still relevant. Finding regression hotspots and writing tests for them is very useful in countering recurring problems.
