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 DesktopWhole but with following changes

• Same, but with LVM ticked also see AlternateLvm

• Same, but with Full Disk encryption ticked also see http://testcases.qa.ubuntu.com/Install/AlternateEncryptedLvm

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

Perform existing 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 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)
