Custom program name causes error when running native tests

[j4m3s]

Having followed the instructions here I now have a version number appended to my firmware binaries. However, I now also get

Building...
Testing...
[Errno 2] No such file or directory: '.pio/build/native/program'

when I try to run my native tests.

Commenting the extra_script out in platformio.ini allows the tests to run fine again in the native . The tests work ok in the embedded environment - the extra_script only causes the problem running native tests.

Yes, the problem is here https://github.com/platformio/platformio-core/blob/develop/platformio/test/runners/readers/program.py#L78

We will think about how to fix it.

That's really interesting - why would appending something to PROGNAME cause an issue there? The updated PROGNAME doesn't seem to be referenced in that function, and the error message doesn't contain anything pointing to the appended PROGNAME either.

(I should say... my python knowledge is minimal, so don't spend time replying if it's going to be obvious to others)

Thanks for the report. Please re-test with pio upgrade --dev.

Does it work now?

[j4m3s]

Yes! Brilliant, thank you :)

How do I get off the dev branch and back onto stable when the next version of platformio is released?
