<b>Warning:</b> Software testing is intended for advanced users and developers. You should only attempt to do this if you know what you're doing. Never rely on code that is in testing for critical work!

There are several different types of testing, which we'll cover below.
Normal updates generally remain in `current-testing` until they have been sufficiently tested by the community, which can last weeks or even months, depending on the amount of feedback received (see [Providing feedback](#providing-feedback)).
"Sufficient testing" is, in practice, a fluid term that is up the developers' judgment.
In general, it means either that no negative feedback and at least one piece of positive feedback has been received or that the package has been in `current-testing` for long enough, depending on the component and the complexity of the changes.
A limitation of the current testing setup is that it is only possible to migrate the *most recent version* of a package from `current-testing` to `current`.
This means that, if a newer version of a package is uploaded to `current-testing`, it will no longer be possible to migrate any older versions of that same package from `current-testing` to `current`, even if one of those older versions has been deemed stable enough.
While this limitation can be inconvenient, the benefits outweigh the costs, since it greatly simplifies the testing and reporting process.
We use an [automated build process](https://github.com/QubesOS/qubes-infrastructure/blob/master/README.md).
For every package that is uploaded to a testing repository, a GitHub issue is created in the [updates-status](https://github.com/QubesOS/updates-status/issues) repository for tracking purposes.
We welcome any kind of feedback on any package in any testing repository.
Even a simple <spanclass="fa fa-thumbs-up"title="Thumbs Up"></span> or <spanclass="fa fa-thumbs-down"title="Thumbs Down"></span> on the package's associated issue would help us to decide whether the package is ready to be migrated to a stable repository.
If you [report a bug](/doc/reporting-bugs/) in a package that is in a testing repository, please reference the appropriate issue in [updates-status](https://github.com/QubesOS/updates-status/issues).
