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 [https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=4043 here].


== Major feature groups and their testing approach ==
The strategy will be divided in two groups one executed once in GDC autobuilders when the Distro is released and another tested continuously on public autobuilders
=== FrontEnd - UI Basic functionalities ===


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


Testing needs :
== GDC Autobuilder  ==
*Built only in python 2.7
*Latest version of Selenium as python module
*Latest version of Firefox
*In order to test Selenium automated based tests (https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=4027 ), the following steps need to be taken before running, on a clean Toaster setup
**ckeck the steps and requirements for “The Selenium automated UI tests” from https://wiki.yoctoproject.org/wiki/Testing_Toaster
*For UI manual testing follow the steps from https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=4029 TCs
**currently working on their automation using Selenium


The first time that Distro is released it will be installed on GDC autobuilder and a serie of build steps going to be applied to that Distro,
once very builset is PASS that distro will be added to the list of supported sitros by QA team 


=== BackEnd functionalities ===
=== LEGACY === Starting with 2.1 M3 the dev team will be taking responsibility for these tests. They will become a part of their internal CI testing.
Covers data integrity, data transfer between Bitbake and Toaster, Start/Stop, building images, configuration, etc


Testing needs:
== Public Autobuilder ==
*Built in python 2.7
*Direct sql requests to local sqlite instance
YP2.1 TODO: Direct SQL tests are going to be hard to maintain and could be done more effectively by either using unit tests in django or by accessing the django ORM. This would also make the test database database backend agnostic.
<!--
Brian's Comments
1) I would like to remove the manual element from all the Toaster tests.
2) unless we are using something from within bitbake that I didn't see these tests do seem to be more amenable to django unit tests since they are already using the orm.models.*
3)we should avoid presuming that we are running from inside poky. referencing ../bitbake/lib/Toaster is a bad idea.
-->
 
*Requires sqlite3 client installed (for manual debugging/investigation)
*BackEnd automated tests are verifying the correctness of the data gathered by the build process as presented in the Backend template: https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=4028
**In order for these tests to run properly, check the the steps for “The oe-selftest Toaster tests” from https://wiki.yoctoproject.org/wiki/Testing_Toaster
*For BackEnd managed mode  manual testing follow the steps from the following template https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=4030
*please validate and add info from Testing Toaster wiki in this section(Test Strategy): https://wiki.yoctoproject.org/wiki/Testing_Toaster
 
== 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
 
<!--
 
=== Toaster Test System (TTS) ===
 
The TTS is a suite aimed at running integration and acceptance tests. Currently, it verifying the correct syntax and form of the Python code, tries to start Toaster in both modes, and runs HTML5 validation on HTML-returning pages.
The tests are designed to be triggered through a continuous integration system.
 
To start manually it, run the tts test runner:
./bitbake/lib/Toaster/contrib/tts/runner.py
 
-->
 
=== The oe-selftest Toaster tests ===
=== LEGACY === These are no longer valid as of 2.1 M3
 
These tests are verifying the correctness of the data gathered by the build process - it tests the bitbake/lib/bb/ui/Toasterui.py and bitbake/lib/bb/ui/buildinfohelper.py files and the interface to the bitbake server process.
 
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 using local poky release
*Create 1 core-image-minimal image
*Create 1 core-image-sato image to check building from cache
*Break a recipe file (by modifying a link, for example)
*Create a new image using broken recipe to check error detection is working
 
 
To run these tests you need to source an environment by issuing:
  source oe-init-build-env
 
then modify the bblayers.conf file to add the meta-selftest layer, create a symbolic link to the Toaster.sqlite file:
  ln -s ../Toaster.sqlite Toaster.sqlite
 
and then run the command:
  oe-selftest --run-tests _Toaster
 
=== 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
*also install the latest filefox extension from selenium located at: http://release.seleniumhq.org/selenium-ide/ and install all the extensions.
 
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
**BackEnd
**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:
*Toaster Backend - Weekly: https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=4028
*Toaster Backend - Managed Mode: https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=4030
*Toaster UI: https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=4027
*Toaster UI - Managed Mode: https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=4029
*Toaster Exploratory - https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=4043
 
== 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 [https://wiki.yoctoproject.org/wiki/Bugzilla_Configuration_and_Bug_Tracking our process for reporting bugs].

This article is the test plan for Distro testing

About Distro Testing

Distro Testing is intended to catch bugs that are distribution specific using the yocto-autobuilder.

Objectives

  • Verify that Distro executes oe-selftest
  • Verify that Dsitro is able to execute componenets (Eclipse, Toaster, WIC)
  • Veirfy that Distro is able to build per package type (IPK, DEB, RPM)
  • Verify that Distro is able to build different image types (LSB, non LSB)
  • Verify that Distro is able to build per architecture (arm, x86)
  • Verify that Distro is able to build per bootloader (systed, init)

    • what’s the easiest way to run the automated tests for a person.
    • holy grail - make a single framework solution.
  • Safari browser
  • TBD - to check with DEV what it’s not covered yet.

Schedule

  • Toaster is tested only at Full Pass by QA Team
    • the plan is to run it according to the Test execution Cycle, after automation is in place.
  • Toaster is tested on Toaster-next branch before every merge into Master by Dev team


Test execution Cycle

Build Sanity Test/E2E Weekly Test Full Pass
Daily Master Y Y NO
Weekly Build Y Y NO
Milestone Build Y Y Y


Sanity Test is described here.
  • run on Toaster-next or poky-contrib.
    • TBD
      • 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
    • oe-selftest Toaster tests
  • selenium UI tests
  • TBD
    • add E2E integration information
    • add more information

Full Pass

  • On full pass all available tests will be run:
    • Automated tests:
      • Django Unit Tests
      • oe-selftest Toaster tests
      • Selenium automated UI tests
    • Manual tests
      • The non-automated tests from the Toaster test runs.
  • Full pass is scheduled to be run on every YP release candidate. The YP is divided in four release milestone structure as described in the YP Schedule.

Dependencies

  • YP Dependencies
    • Bitbake works
  • Some changes in the Toaster UI might affect running the UI automated tests using Selenium
    • e.g. Changing the element ID’s in the Toaster pages reflected in failing all UI related automated TC’s
