Enjoy Fighting regressions with git bisect
As Git Bisect is not clear a lot of people, here is a nice PDF to look at Enjoy Fighting regressions with git bisect, #LinuxCon EU 2013.pdf
it is about “Linux” combinational explosion… Bug software have the following properties (not desired):
- has many different “configurations”
- may fail under one configuration but not another
N configurations, T tests and C new commits means that a release needs:
C * N * T tests performed
where N and T, at least, are growing with the size of the software.
Git Bisect help find a first bad commit and use a binary search algorithm for efficiency if possible.
