While current testing suite of KIO-FUSE tests individual operations pretty aptly, it lacks the support to put KIO-FUSE through regression tests. KIO-FUSE has not been through regression tests and chances are, doing so would uncover bugs that previously went undetected. KIO-FUSE is updated fairly frequently and new features are still being added, making regression testing a necessity to prevent new bugs from creeping in.
The lack of regression tests in KIO-FUSE’s current testing suite can be fixed by integrating XFSTESTS with it. XFSTESTS is considered as the quintessential file system regression testing suite and KIO-FUSE would benefit greatly from it. A more rigorous testing regime would translate to an even more robust and reliable filesystem. Testing KIO-FUSE would mean we’re testing KIO slaves as well. As of now, XFSTESTS doesn’t support FUSE, and that’ll have to be added as a part of this project. FUSE support for XFSTESTS would be a major plus since it’d allow hundreds of file systems written using FUSE to be tested.
The project not only benefits KIO, KIO-FUSE and KDE, but the FOSS community as a whole.
FUSE support for XFSTESTS
Patched XFSTESTS file system regression testing suite for FUSE support. Go through this blog I wrote to know more. The patch can be found at github.com/bhumitattarde/XFSTESTS-FUSE-patch and is under review.
XFSTESTS support for KIO-FUSE
Patched KDE KIO-FUSE for XFSTESTS file system regression testing suite support. Merge request can be found at invent.kde.org/system/kio-fuse/-/merge_requests/58. Core code is approved but unit tests and documentation are under review as of now.

Ran all tests and sorted the results in tabular, color-coded fashion. The spreadsheet can be found at docs.google.com/spreadsheets/d/1LkeBuplbXXJxoXBS-ApsfA1trRLy1CB6PA5a8E1LyyY/edit?usp=sharing. Switch to the

Thank you KDE for selecting me as a Google Summer of Code mentee. The community couldn’t have been more welcoming. I still remember the first mail I sent to the KDE mailing list asking for suggestions to get started (without a subject line as well, sorry folks :P) and the help that poured in.
I cannot be more thankful to my mentors — feverfew (Alexander Saoutkin) and Fabian Vogt. We are from very different timezones but they still communicated with me almost daily. They were patient with me throughout the development period and even before GSoC started when I was just starting to understand what FUSE, KIO-FUSE are. They were amazing guides and helped me promptly whenever I was stuck.
