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. Note that the information provided in this article, or articles linked here, is subject to changes when needed as to reflect the actual activities held for the current version of the Yocto 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 Areas

Each internal project, under Yocto Project, is an area subject to a testing process. Areas are grouped by the nature of their functionality, as follows:

Build System

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, through 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.

Compliance Testing

Compliance test suites / frameworks used:

• LSB tests
• POSIX 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

• Objective

  • Track the run-time performance of targeted systems;

• Indicators

  • Boot time for systemd and sysvinit;
  • Image size from Buildhistory to track regression;
  • Piglit test suite results;

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.

Distribution Support

Criteria

The OS distribution version is still maintained at the time of the Yocto Project release (1.5 release date is: Oct. 18, 2013)
