= OEQA (v2) Framework =

== Introduction ==

This is version 2 of the OEQA framework. Base clases are located in the
'oeqa/core' directory and subsequent components must extend from these.

The main design consideration was to implement the needed functionality on
top of the Python unittest framework. To achieve this goal, the following
modules are used:

    * oeqa/core/runner.py: Provides OETestResult and OETestRunner base
      classes extending the unittest class. These classes support exporting
      results to different formats; currently RAW and XML support exist.

    * oeqa/core/loader.py: Provides OETestLoader extending the unittest class.
      It also features a unified implementation of decorator support and
      filtering test cases.

    * oeqa/core/case.py: Provides OETestCase base class extending
      unittest.TestCase and provides access to the Test data (td), Test context
      and Logger functionality.

    * oeqa/core/decorator: Provides OETestDecorator, a new class to implement
      decorators for Test cases.

    * oeqa/core/context: Provides OETestContext, a high-level API for
      loadTests and runTests of certain Test component and
      OETestContextExecutor a base class to enable oe-test to discover/use
      the Test component.

Also, a new 'oe-test' runner is located under 'scripts', allowing scans for components
that supports OETestContextExecutor (see below).

== Terminology ==

    * Test component: The area of testing in the Project, for example: runtime, SDK, eSDK, selftest.

    * Test data: Data associated with the Test component. Currently we use bitbake datastore as
      a Test data input.

    * Test context: A context of what tests needs to be run and how to do it; this additionally
      provides access to the Test data and could have custom methods and/or attrs.

== oe-test ==

The new tool, oe-test, has the ability to scan the code base for test components and provide
a unified way to run test cases. Internally it scans folders inside oeqa module in order to find
specific classes that implement a test component.

== Usage ==

Executing the example test component

    $ source oe-init-build-env
    $ oe-test core

Getting help

    $ oe-test -h

== Creating new Test Component ==

Adding a new test component the developer needs to extend OETestContext/OETestContextExecutor
(from context.py) and OETestCase (from case.py)

== Selftesting the framework ==

Run all tests:

    $ PATH=$PATH:../../ python3 -m unittest discover -s tests

Run some test:

    $ cd tests/
    $ ./test_data.py
