[SOCIS] Testing Framework

Tue Sep 24 23:05:32 UTC 2013

Looking at the macros, it looks like some/all of the current test support macros could be wrappers for Unity calls.

Beyond that we need to look at some specific tests to see what other things can be done based on patterns

Also our tests can do printf, printk, or buffer a screen or so of output and then print that at a more steady state time.

Hi Marcin,

This looks interesting! How do I try out these changes?

Could you tell us who the upstream maintainer is for Unity?
We may be able to get some feedback from him (and thus increase the likelihood the changes will be upstreamed... :)

Thanks!
Cindy

Subject: Re: [SOCIS] Testing Framework

Hello all,

Another update on my SOCIS project. Last week I have been fixing bugs on the modifications I have done to Unity to be used with the future RTEMS testing framework.

For those interested the changes I have made so far are here: https://github.com/marcinbujar/Unity/compare/ThrowTheSwitch:master...master

These additions to the unit testing tool will hopefully allow me work towards higher automation of testing.

This week I have been using the new waf build system to compile RTEMS so that I can start using unity for testing. So far I am still working my way through build errors but I am making steady progress.

Marcin

Hi again,

I would just like to update everybody that the work on my SOCIS project on
RTEMS testing framework is going well. This week I worked on adding new
features to the Unity unit testing tool, primarily adding JSON output support
as mentioned in my previous update, but also looking how to compile the program
on 16bit architecture so that it is executable on such RTEMS supported platforms.

it would be nice to know the work flow if I write tests for this new frame work.  Do I simply write C files according to the frame work requirements and then run a script that generates the appropriate glue code?

How are the RTEMS configurations provided for a particular test program?

The plan is to have as much automation as possible, but we dont have all the details yet. There will most likely be pre-generated skeleton test files or templates to use to write new tests. This is the next step in my project. I will post more information about this to ask for feedback once I know more.

Next week I will be fixing any remaining issues with the output and also
implementing 16bit support for unity. Once complete this tool will hopefully be
ready to use with RTEMS testing.

Why does it matter for the test framework which word size an architecture has?

As far as I know Unity does not fully support some test functions specific to 16bit, so my job is to make sure that it does. I will be investigating this and other compatibility issues this week.

And to answer the previous questions, I have forked Unity on github so any features that I develop specifically for RTEMS can be pulled to the upstream repository once they are ready and if the maintainers find it useful. And finally I do not have a developer blog but I may actually create one in the future!

Thanks for the questions!

Marcin
