The Fedora installation test automation project covers the whole installation from retrieving installation media to first boot. Details are below:

====Problem Space====

The Fedora installer is a complicated software application that often requires significant setup time to properly and efficiently test.  Installer failures typically come from the following areas:
 +
 
 +
''' Image Sanity '''
 +
# ISO file size is too large
 +
# Invalid SHA256 checksum
 +
# Invalid implanted ISO md5sum
 +
# Install environment - anaconda has specific application, library and config file format requirements.
 +
# Versions check
 +
 
 +
''' Boot Methods'''
 +
# Boot media improperly built (PXE, boot.iso, DVD, efidisk.img)
 +
# Installer fails to boot as a KVM guest

# Installer fails to boot as a XEN guest

# Install fails to proceed in accordance with the directives in the ks.cfg file

The purpose of auto test is to simplify testing,save time, improve efficiency.So the auto-test should help us to solve the following problems:
+
# Fail to detect existing storage device(s)
 +
# Failure to clear stale data off of existing devices
 +
# Unable to add iSCSI volumes
  
* the system should be small enough for personal use

* very easy interface for user to set up some services due to some special cases,such as ftp/nfs/http install,etc
+
# Failure when attempting to resize existing partitions
* test result is easy to check
+
# Failures while attempting to re-use existing partitions

*  web-based interface help to setup some needed services due to some special cases. Modify,add or delete test cases,

Overview

The purpose of AutoQA installation test automation is to simplify testing and improve test efficiency. The AutoQA install test project should address the following problems:

  • The system should be easy to allow for tester and developer use
  • Have clear documentation for customizing and creating new tests
  • Support test execution using existing Fedora infrastructure services, but not require them
  • Test results are easy to verify

  3. File conflicts during package install
  4. Package order and install errors in install.log
  5. Improperly formatted comps.xml data

Boot loader configuration

  1. Unable to properly detect other operating systems
  2. Failure while setting up chainloader for another OS

Upgrade system

  1. Failure to detect previously installed systems
  2. Errors while attempting to update bootloader configuration during upgrade
  3. Package upgrade errors in upgrade.log

Recovery

  1. Rescue mode fails to detect existing installations (lvm, raid, luks)
  2. Rescue mode fails to establish networking
  3. Problems saving traceback information (local disk, bugzilla, remote server)
  4. Anaconda unable to download and use updates.img (from install source, local media or URL)
  5. Unable to transition to debug mode

Proposed Solution

The project will be developed based on the AutoQA framework and use the virtualization environment (libvirt,kvm-qemu). The installation automation will be deployed by the Fedora kickstart installation. virt-install will be used to create the guest.virtio is used to get the anaconda logs. The details can be found at Is anaconda broken solution

Active Ingredients

  • AutoQA must be packaged and available in Fedora infrastructure
  • A valid backend test harness is packaged and available in Fedora infrastructure (Autotest currently being used by AutoQA)
  • Knowledge of TurboGears or TurboGears2
  • A new AutoQA test watcher may be required to initiate automated tests whenever CD and DVD ISO images are available for testing (post-iso-build)
