Yocto 1.2 Overall Test Plan
This overall test plan defines test scope, test strategy, test configurations as well as test execution cycle for Yocto v1.2 program.
Features to Be Tested
- Core OS: The core OS feature included Yocto kernel, distro components(like connman & zypper), file system, device drivers (e.g. Intel Graphics Driver).
- Core build system: It includes basic core build test and other build feature test. Performance and different distribuitions support will be tested also.
- Hob2: It includes functional tests for both frontend and backend of hob2.
- Yocto ADT: ADT testing only covers toolchain test.
- Power/Performance: QA will check the CPU power behavior by software level tool, such as powertop. Real Power consumption with idle is collected.
What will not Be Tested in Yocto v1.2
Following feature categories won't be tested by QA team in Yocto v1.2:
- Eclipse plugin: QA will not cover ADT plugin and ADT tools testing. -- (ADT team will cover them)
- Documentation: QA will not validate the correctness of each documentation.
- License file: license files and legal process is owned by Distro team.

Test Strategy and Approach
QA will cover following tests for each target in each round fullpass testing.

| routerstation | yes | yes* | |||||
| Pandaboard | yes | yes | yes | ||||
Note:
- 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 picked up for stress test, because it is powerful with 12 CPUs and 2GB memory. Moreover, it is a server, which needs more stress tests. The other test boards, like blacksand and eMenlow do not have powerful CPUs, that's why we do not use them for stress test.
| Core build feature | Functionality | Performance | Distribution Support |
| Yocto build | yes | yes | yes |
| Hob2 | yes | n/a | n/a |
| Build Appliance | yes | yes | n/a |
| Other build features | yes | n/a | n/a |
Note:
- For other core build features not listed, QA will cover functionality test if there is no specific requirement for performance and distribution.
Test Levels
The Yocto 1.2 will be tested from the following different test execution levels.
Sanity Test
Sanity Test is a very brief and quick test. It is integrated with each build process (including incremental build) in autobuilder system. It checks image basic functionality, such as booting, network, zypper etc. Its results will be published in build web page and referred by the other testing. It is fully automation test and its execution time should be less than 10 minutes.
Test Frequency: Sanity test will be run on autobuilder system against daily build image.
Weekly Test
Weekly test is a test cycle against the weekly image released through distribution team. It will do new feature exploring, bug verification and regression testing. It includes more testing in component and system usage rather than Sanity Test. Weekly test will also manually check key components behavior, such like X window, connman, multimedia.
Test Frequency: Weekly Test is against weekly image and occurred each Thursday if image is ready on autobuilder system. It will cost 3 days for one round weekly test.
Fullpass Test
In milestone test, test team will perform a full validation testing for candidate build, following test will be involved. It includes more tests than Sanity and Weekly Test.
- Functional Test – which will test the items in Feature List(defined in https://wiki.yoctoproject.org/wiki/Yocto_1.2_Schedule), cover Core OS & System usage, hob2, build appliance, and other build features, etc.
- Stress Test – system should be alive and functional in 24 hours workload test.
- Power and Performance Test – which follow the power and performance test plan
- Compliance Test - system level test suites will be chosen, LTP, POSIX and LSB.
Test Frequency: Fullpass test will be performed against each RC build for milestone. It will cost a whole week for one round fullpass test.
Regression Test
Regression test is a set of tests to verify the new feature development does not introduce new issues to previous workable functionality. It covers the most important features check for both BSP/QEMU and yocto build features. The testcase list is updated after one milestone is finished and won't be updated until the next milestone is finished.
Test Frequency: Regression test will be run on PRC autobuilder system against daily build image.

Test Automation
To reduce testing time, test automation will be adopted in the testing. Following test will be implemented as automation:
- Sanity Test
- Part of Weekly Test
- Stress Test
- Core build Performance Test
Test Infrastructure
If QA has resource, test infrastructure will be investigated in Yocto v1.2. Automation test cases development should be test infrastructure independent.
Test Design
This is a overall test design for test components which will be covered QA testing. Detailed test cases design will be covered in Test Execution Plan.
System & Core OS(Covered in Weekly Test)
- 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 for software update 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
- 3G
- ... etc
(Basic functionality for tested features will be exercised as well as new functionality added in each release.)
Core Build System(Covered in Fullpass Test)
- Functionality Test: Test Core build feature on standard host configuration. For example:
- kernel interactive targets
- non-GPLv3 build
- sstate
- core build in virtual machine
- ... etc
- Distribution support Test: Test Core buld on latest Ubuntu, Fedora and Opensuse Hosts
- Hob Test: Main UI and component functionality are validated (Some cases defined in weekly and some in fulpass)
- Performance Test: Check Core build performance on standard host(Defined in perfromance test webpage)
ADT Test(Covered in Weekly Test)
- Toolchain test, including compiler, libraries, etc.
Stress Test(Covered in Fullpass Test)
Stress testing refers to tests that determine the robustness of software by testing beyond the limits of normal operation. Stress tests commonly put a greater emphasis on robustness, availability, and error handling under a heavy load, than on what would be considered as correct behavior under normal circumstances.
- Test Method: 24 hours workload (Helltest + Crashme) test should pass.
Power/Performance Test(Covered in Fullpass Test)
Power/Performance Test is to collect the power/performance data and status of Yocto image on defined BSP.
- Test Method: Power test will check if Yocto is power saving friendly, that CPU should support and enter different power saving stage. For performance test, memory footprint under specific workload will be collected.
Compliance Test(Covered in Fullpass Test)
Compliance Test is targeted to validate system level health with different system test suite.
- LTP test suite
- POSIX test
- LSB test
