Abstract#
Provides an application abstraction layer and APIs for testing. Implements common code and several safety requirements.
Motivation#
Currently there is no abstraction layer to make component tests independent from application frameworks like ‘Fixed Execution Order Framework’. With the abstraction layer you can test against different execution frameworks and in different environments (linux & qnx).
Rationale#
The lifecycle states are designed like in usual execution frameworks to emulate the same behavior also in testing. Also error handling and health monitoring is part of the framework for emulation of all aspects. Different communication frameworks can be plugged in to use in testing. The idea is also to use the framework as a testing area for our future Autosar process.
Backwards Compatibility#
It can have impact in the Feo Framework because we need only one Lifecycle interface.
Open Issues#
[Any points that are still being decided/discussed.]
Note
While a CR is in draft, ideas can come up which warrant further discussion. Those ideas should be recorded so people know that they are being thought about but do not have a concrete resolution. This helps make sure all issues required for the CR to be ready for consideration are complete and reduces people duplicating prior discussion.
