This article is the test plan for Toaster.

About Toaster

Toaster is a web interface to the Yocto Project’s OpenEmbedded build system that allows a user to run and build his own builds. The information is collected and stored in a database, so Toaster provides information and statistics about the build process. Toaster can be used to configure and start builds on multiple remote build servers.

Currently positive testing is being executed for existing features. Tasks:

  • Validating the current build (running regression test)
  • Bug & Feature verification
  • Exploratory on existing functionalities

Objectives

Verify all Toaster components to be fully functional.

Components to be verified:

  • UI interface

The testing objective involves only positive testing for existing features on Toaster. Perform exploratory testing focusing on newer features

  • this can sometimes generate new test cases.

Verifying the bugs and features.

Scope

Testing scope has been agreed upon as local installation only, using sqlite database on Fedora and Ubuntu operating systems on Firefox browser.

New features are to be tested as they are finished with test cases written for them once features are stabilized.

UI features being tested:

  • Create new project
  • Modify project settings and variables
  • Add/Remove layers to project
  • Building images
  • Build details
  • All builds report table
  • Build data
YP2.1 TODO - we need toaster-next on poky-contrib to be tested. Basically to add some of the poky-contrib branches to be tested routinely
YP2.1 TODO - add mysql testing as well

Test Strategy

There are several test approaches for Toaster Testing, such as:

  • Perform test cases agreed upon the development during periodic full passes according to the Schedule
  • Write new test cases based on developer request or new features requires it.
    • Maintain current test cases and update them accordingly
  • Perform exploratory testing on existing functionalities.
    • YP 2.1 Testopia template here.

Major feature groups and their testing approach

FrontEnd - UI Basic functionalities

Toaster UI features are tested such as links, buttons, tables, pages basic functionalities.

Testing needs :


Test automation

Toaster has 3 testing suites, targeted at verifying different parts of the system.

Django Unit Tests

Toaster is primarely a Django application. As such, it makes use of the Django test system that runs unit tests on mock data to ensure pieces of functionality work as expected, and prevent regressions.

To run the django unit tests, invoke them as with any Django test suite 

./bitbake/lib/toaster/manage.py test

To add unit tests, simply add needed tests to the _tests.py_ file in the module you're editing. 

YP2.1 TODO: QA start running tests


The selenium automated UI tests

The automated UI tests are targeted at validating and identifying regressions in the UI pages. These tests are based on the Selenium framework to drive interactions in the interface.

The selenium tests require a couple of components:

  • scrot (a screen capture utility) and pip - a utility for installing python modules. The following is how you install it for ubuntu:
sudo apt-get install scrot python-pip python-virtualenv
virtualenv t-selenium
source ./t-selenium/bin/activate
pip install selenium
  • Since this is a web application, the UI can also be tested from a mac. To install the requirements there do:
sudo easy_install pip
sudo pip install virtualenv
virtualenv t-selenium
source ./t-selenium/bin/activate

The selenium tests are located in: 

./ bitbake/lib/toaster/contrib/tts/toasteruitest

You run them with: 

./bitbake/lib/toaster/contrib/tts/toasteruitest/run_toastertests.py

The above command takes the list of the tests to run from the toaster_test.cfg file. The tests themselves are located in toaster_automation_test.py. The toaster_test.cfg file has a couple of important variables in it separated by which os you are running the tests on. These varables control where the toaster instance is located (defaults to http://127.0.0.1:8000) what browser to use (firefox is safest for selenium though there is a chrome driver available as well), what tests to run and what log level to save data at.

In order for these tests to run properly, the following steps need to be taken before running, on a clean toaster setup:

  • Create new project named "selenium-project" using local poky release
  • Create 1 core-image-minimal image
  • Break a recipe file (by modifying a link, for example)
  • Create a new image using broken recipe to check error detection is working
  • Fix the recipe broken in previous step
  • Create 1 core-image-sato image
YP2.1 TODO: Update this section, since the steps are a WIP for automation.

In order to run all current tests, you need to modify the configuration file "toaster_test.cfg" with the following line: 

test_cases = [901, 902, 903, 904, 906, 910, 911, 912, 913, 914, 915, 916, 923, 924, 940, 941, 942, 943, 944, 945, 946, 947, 948, 949, 950, 951, 955, 956]


The code for running Selenium UI tests is available here: http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=alimon/toaster_tests_squash

Test Approach

Regression Regression testing is being performed by the QA team for Backend and Frontend according to the Schedule matrix. Part of regression Backend and Frontend are covered.

Sanity testing

  • Not covered at this moment
  • TBD following DEV discussions

Performance and Stress

  • Testing two concurrent builds
  • TC…

Load testing

  • Not covered
  • TBD

System Integration Testing

  • Not covered (maybe covered by DEV w/ Jenkins)

Regression

  • All Full pass tests for
    • FrontEnd

Maintaining the test cases

Toaster test cases are officially stored in Testopia, the Yocto Project test case management system. Testopia is a test case management platform and an extension for Bugzilla developed by the Mozilla Foundation that helps organize test cases using a tight relation with elements in Bugzilla. More details on Testopia, can be found on the YP Wiki at https://wiki.yoctoproject.org/wiki/Testopia.

A quick start guide for Testopia is found on the Testopia wiki at https://wiki.yoctoproject.org/wiki/Testopia#What_do_I_need_to_start_using_Testopia.3F.

As currently Testopia is structured, all Toaster test cases are stored under Classifications/Build System & Metadata/ Toaster component within Testopia. All the test cases are organized in Test Run Templates as following:

Submitting Bugs

Being part of the Yocto Project, Toaster follows the same Yocto Project guidelines and principles. The guidelines can be found at https://wiki.yoctoproject.org/wiki/Community_Guidelines. Toaster bugs are no different and are tracked into Bugzilla, the official Yocto Project bug tracker. Learn more about our process for reporting bugs.

      • need info from DEV owners on what Sanity testing is done by them
      • detail the set of tests. e.g. django unit tests, Toaster oe-selftest

Weekly test

  • Weekly testing is performed on a weekly basis on the poky weekly build.
  • E2E consists of all automated tests that can be run on Toaster
