We have several options for parallel processing in oeqa, parallel execution of modules, threading and mulitple processes for the runners. After much experimentation is appears the most scalable and least invasive approach is multiple processes using concurrenttestsuite from testtools. This means we can drop the current threading code which is only used by the sdk test execution. oeqa/decorator/depends: Remove threading code Revert "oeqa/sdk: Enable usage of OEQA thread mode" This reverts commit adc434c0636b7dea2ef70c8d2c8e61cdb5c703b1.

= 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
