Slides for my talk at LibreOffice conference in Bern

I’d like to share the slides I used for my talk at LibreOffice Conference 2014 in Bern, Switzerland.

During my talk, I hinted that the number of unit tests for Calc have dramatically increased during the 4.2 bug fix cycle alone. Since I did not have the opportunity to count the actual number of unit test cases to include in my slides, let me give you the numbers now.

The numbers represent the number of top level test functions in each test category. Since sometimes we add assertions to existing test case rather than adding a new function when testing a new bug fix, these numbers are somewhat conservative representation of how much test case we’ve accumulated for Calc. Even then, it is clear from this data set that the number has spiked since the branch-off of the 4.2 stable branch.

Now, I’ll be the first to admit that the 4.2 releases were quite rough in terms of Calc due to the huge refactoring done in the cell storage structure. That said, I’m quite confident that as long as we diligently add tests for the fixes we do, we can recover from this sooner rather than later, and eventually come out stronger than ever before.
