I’ve been trying to find any documentation regarding xtrabackup test. i found them in /usr/share/percona-xtrabackup-test/. Anywhere I can find info on this?
There is no specific documentation for this - to understand the tests you have to have a bit if knowledge about shells scripts. The XB test suite is simply a set of shell scripts - http://bazaar.launchpad.net/~percona-core/percona-xtrabackup /2.1/files/head:/test/
I do have some knowledge, but it is quite time consuming trying to troubleshoot why it the script isn’t running. Are there any plans for documentation?
