  [Test Plan]
- <Link to wiki SRU backport page>TBD
+ 
+ DEP-8 Tests:
+ 
+ simpletest - Confirms bind9 daemon starts successfully and dig can find
+ 127.0.0.1 through the default setup of bind9
+ 
+ zonetest - Added in this update, currently in lunar. Confirms the
+ functionality of named and bind9 by creating a local DNS zone and
+ domain, and having dig look it up
+ 
+ dyndb-ldap - Verifies functionality of bind-dyndb-ldap against the
+ updated bind9 package with a basic setup. This also fails intentionally
+ prior to bind-dyndb-ldap being rebuilt against the package, as this is a
+ necessary step for bind9 updates.
+ 
+ validation - This test is provided by Debian and consistently fails both
+ before and after the update due to several issues. It is marked as
+ flaky, and does not block autopkgtest passing overall
  
  [Regression Potential]
- Upstream has an extensive build and integration test suite. So regressions 
would likely arise from a change in interaction with Ubuntu-specific 
integrations, such as in relation to the versions of dependencies available and 
other packaging-specific matters.
- <Also, ...>
+ 
+ Upstream has an extensive build and integration test suite. So
+ regressions would likely arise from a change in interaction with Ubuntu-
+ specific integrations. Alternatively, regressions may arise for users
+ due to behavior changes from the many bug fixes and minor feature
+ updates.
