I got used to the following approach on bugfixing phase of the project development. The developer should add SVN commit number as a comment to the JIRA issue when resolving it. Latest artifact from CI-server shows build number which include major version, branch name and commit number. This approach helps QA easily to identify whether the bugfix was included in the latest build or not. Even when same issue was reopened and fixed again.
After moving from SVN to Git we lost incremental commit number. It is possible to solve this problem with tagging the code but tags are tied to the sprint numbers. And in case of the issue reopening this approach moves this issue resolving on the next sprint. But client is dissatisfied with the fact of having certain issue unfixed for a several sprints.
So, how do you identify bugfix commits in for QA environment? Thanks.
UPD: The question is NOT about linking issues to commits, but about ability of QAs figure out whether certain fix (ticket) is included in certain build just by looking on build number and ticket comments.
