Introduction
This article is the overall test plan for version 1.5 of the Yocto Project. It contains an overview of the testing process, such as testing areas, types, cycles and reports, along with a summary and objective for each of the conducted validation activities. Further on, sections may be linked to other articles that contain further details or information related to them. As a note, the information provided in this article, or one that's linked here, is subject to changes at any time, as to reflect the actual activities held for the current version of the project.
Objectives
The test process is mainly focused to track and review the quality and performance of the Yocto Project, along with its reference system and internal projects. The plan also includes identifying and tracking areas subject to improvement, regression, validation of enhancements and bugs, development of testing methods with emphasis on automated testing. Documentation and licensing status is not included in the scope of the testing process, unless otherwise noted e.g. as part of the process of verifying new features.
Test Environment
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 levels | Atom-PC | NUC | Emenlow | Sugarbay | Jasperforest | Crownbay | FRI2 | Beagleboard | RouterstationPro | MPC8315e-rdb | P1022ds-rdb |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Weekly | Yes | Yes | Yes | Yes | Yes | ||||||
| Full Pass | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes |
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.

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.)
Compliance Testing
Compliance test suites / frameworks used:
- LSB tests
- POSIX tests
- LTP tests
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
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
