Sine Ubiquity LVM and LUKS support is nearing completion, here is the test cases that you should performed: once over (to verify the spec); automated in jenkins (for continuous integration); manually (for ISO testing), as appropriate.

== Automatic Partitioning, whole disk (2 tests) ==

Perform existing [[http://testcases.qa.ubuntu.com/Install/DesktopWhole|DesktopWhole]] but with following changes
 * Same, but with LVM ticked also see [[http://testcases.qa.ubuntu.com/Install/AlternateLvm|AlternateLvm]]
 * Same, but with Full Disk encryption ticked also see [[http://testcases.qa.ubuntu.com/Install/AlternateEncryptedLvm||AlternateEncryptedLvm]]

== Automatic Partitioning, whole disk, LVM twice in a row (1 test) ==

Perform existing [[http://testcases.qa.ubuntu.com/Install/DesktopWhole|DesktopWhole]] again but with following

Pre-requisite:
 * Full-disk installation, LVM whole disk

Test-case: 
 * Overwrite, Full-disk installation, LVM ticked.

Due to partman-lvm quirks this might fail or show extra unneeded dialogues. (This is believed to be fixed, and hence both installations should be identical experience)

== Automatic Partitioning, Resize, existing LVM (4 tests) ==

Perform something similar to the existing testcase [[http://testcases.qa.ubuntu.com/Install/DesktopResize]], but have an LVM group across the whole disk.

Pre-requisite:
 * Full-disk installation, LVM whole disk

The goal here is to:
 * Using Automatic Partitioning 
 * Try to get a sensible installation within the existing LVM group
 * Without destroying data
 * Resizing LVM group and creating a second one

Attempt test case combinations of:
 * In the "Install Ubuntu" (ubiquity-only) and "Try Ubuntu" (live-session) mode
 * Using Automatic and Manual partinioning

== Automatic Partitioning, Resize, existing encrypted LVM (4 tests) ==

Perform something similar to the existing testcase [[http://testcases.qa.ubuntu.com/Install/DesktopResize]], but have an LVM group across the whole disk.

Pre-requisites:
 * Whole disk, encrypted, automatic partitioning installation.

The goal here is to:
 * Try to get a sensible installation within the existing LVM group, insie
 * Without destroying data
 * Resizing LVM group and creating a second one

Attempt test case combinations of:
 * In the "Install Ubuntu" (ubiquity-only) and "Try Ubuntu" (live-session) mode
 * Using Automatic and Manual partinioning

== Manual Partitioning (5 tests) ==

Perform regular manual partitioning test case [[http://testcases.qa.ubuntu.com/Install/DesktopManual|DesktopManual]]
 
Perform manual partitioning with:
 * 2 partitions: separate /boot  & encrypted /
 * LVM (e.g. LVM spanning 2 disks, with LVs: /boot /usr /home /)
 * 2 partitions: separate /boot & encrypted LVM group with LVs: /boot /usr /home /)
 * 2 partitions: unencrypted / & encrypted /home

== Conclusions ==

The above 15 tests should ideally be performed at least once on various types of hardware (VMs/bare metal) x supported arches.

Above tests are expected to uncover:
 * bugs in the ubiquity implementation
 * flaws in the design specification
 * existing and known bugs in the underlying technologies (d-i, partman and its components)
 * new bugs in the underlying technologies (d-i, partman and its components)
 * missing functionality or features in the underlying technologies (d-i, partman and its components)
