Introduction

This test plan defines test targets/components, scope, strategy, configurations as well as test execution cycles for 1.5 version of Yocto.

Targets / Components to Be Tested

  • Core build system: includes build system tests also using additional features and tweaks for it.
  • Hob2: It includes functional tests for both frontend and backend of Hob2.
  • Yocto ADT: It includes cross-toolchain, Eclipse plugin tests.
  • BSPs: The core OS feature included Yocto kernel, distribution components(like connman, smart updater & zypper), file system.
  • Performance: Checks the CPU power behavior by software level tool, such as powertop. Real Power consumption when idle is collected. The performance of the build system is also recorded.
  • Distribution support: Current versions for supported distributions are tested along with one previous version and the beta release for the next one (the supported distributions are Ubuntu, Fedora, CentOS and OpenSUSE).
  • Compliance testing: LSB, LTP and POSIX tests are ran on the the selected targets.
  • Stress testing: Helltest + Crashme test suites are ran.

What will not be tested in Yocto v1.5

Following feature categories won't be tested by QA team in Yocto v1.5:

  • Documentation: QA will not validate the correctness of each documentation.
  • License file: license files and legal process are owned by Distro team.

Notes:

  • Fullpass testing defined in execution plan will be performed against sato-sdk image.
  • The atom images are both emgd and no-emgd images

Test Strategy and Approach

QA will cover following tests for each target in each round fullpass testing.


The following matrix represents the Yocto Project components mapped by the test areas and by the Weekly and Full pass test levels.

Test Areas
Components Weekly Full Pass
Build System Bitbake Yes* Yes
Build performance Yes* Yes
Metadata Yes* Yes
Distribution Yes* Yes
Target Build Appliance Yes
QEMU images Yes* Yes
BSP images Yes* Yes
Stress Yes* Yes
Target performance Yes* Yes
Compliance Yes
Tools Eclipse Yes* Yes
ADT Yes* Yes
Autobuilder Yes* Yes


Note:

  • On weekly test, the basic BSP will be covered: Atom-PC, Beagleboard, Routerstationpro, MPC8315e-rdb, P1022ds-rdb, and all the QEMU images (arm, x86, x86_64, ppc, mips)
  • as mentioned in the Weekly test section, the weekly tests will cover the basic functionalities of the component.
  • Compliance Test on Beagleboard and routerstation will only cover LTP and POSIX Test, since LSB test suite does not support ARM and MIPS.
  • Jasperforest is selected for stress test, because it is powerful with 12 CPUs and 2GB memory. Moreover, it is a server, which needs more stress tests.

The following matrix represents Full pass and Weekly coverage of BSP testing.

Test Areas

The testing areas are defined by the Yocto Project component covered, and grouped by the components nature and destination, as follows:

Build System

Including the build engine and the surrounding components, that provide the means to build an image or bake a bit of software. In this area the build-time tests are executed.

BitBake

Functional testing of BitBake, as a build engine, with all its features and components, against various configuration and scenarios.

HOB

Functional and usability testing of HOB as a graphical user interface for BitBake.

Metadata

Testing the core metadata of the Yocto Project is mainly covered in the overall testing process, of other #Test Areas like #BitBake and #HOB mentioned above.

Build Performance

The performance of the build system is tracked, with regards to time spent on passing through a build process, in multiple, commonly used, configurations.

Performance Test

Target System

Area focused on a target operating system or an application that comes with it, as the output of a build process. In this area the run-time tests are executed.

QEMU Image

Covering all core, QEMU, machine definitions:

  • qemuarm
  • qemumips
  • qemuppc
  • qemux86
  • qemux86-64

BSP Image

Covering BSPs included in the Yocto Project:

  • atom-pc
  • beagleboard
  • mpc8315e-rdb
  • routerstationpro

Atom-PC, Beagleboard, RouterstationPro, MPC8315e-rdb, P1022ds-rdb, QEMU (arm, ppc, mips, x86, x86_64). The images tested will be core-image-sato-sdk. The scope of BSP testing is to make sure that the core BSPs have basic functionality, like described below:

  • Boot Test: Check if Yocto image is bootable with the bootloader.
  • Installation/SW Update Test: Validate the Yocto image installation on hardware platform and software install/removal functions from the end users' perspective. Using zypper/rpm/SMART updater for software updates with hardisk installed image.
  • Common system usage Test: shutdown/restart, suspend/resume, init 3/5 boot.

Component Test (aka. Feature Test): Based on sato image features to test. For example:

  • Perl
  • Rootless X
  • Opening 3rd party application
  • Code compiling and building binaries on the *-sdk images
  • Continuous system updates analysis

(Basic functionality for tested features will be exercised as well as new functionality added in each release.)


System Performance

The run-time performance metrics will be measured using the following methods:

  • measure boot time for SystemD and SysVinit features
  • record image size from buildhistory to track regression
  • use Phoronix Test Suite tests to benchmark Yocto images
  • run Piglit test suite

Compliance

LTP, POSIX and LSB test suites are ran on the targets. The hardware used for this is Huron River. The images used are core-image-lsb-sdk. [TODO]

Stress testing

Stress tests are run on Beagleboard and Jasperforest BSPs. Details as follow:

  • Beagleboard core-image-sato-sdk image is tested using LTP and Crashme stress tests
  • Jasperforest core-image-lsb-sdk image is tested using Helltest and Crashme stress tests

Developer Tools

Application Development Toolkit

ADT testing includes tests for ADT-installer, meta-toolchain-sdk and user build sdk. It will be covered in Weekly and Fullpass testing.

  • Cross-toolchain install&compiling Test
  • relocatable SDK
  • ADT installer
  • toolchain tarballs
  • yocto build tree

Eclipse IDE Plugin

Eclipse plugin tests will cover the basic functionalities. This includes installation, configuring Yocto Project ADT settings, Yocto BSP, Bitbake project and project compiling and deployment to the target. Based on the features that will be implemented, new test cases will be added, to support Windows and Mac support. This will be more detailed in the Features section.

  • headless build
  • C/C++ project creation
  • debug/deploy
  • user space tools
  • Bitbake project

Build Appliance

The basic functionality of the Build appliance will be tested. The tests consists on building successfully a build-appliance-image, launch HOB.
