Features from newer python versions cause syntax errors

[asfaltboy]

For example using f-strings in tests (a python 3.6 feature), causes a SyntaxError when passing the test module so urce to ast.parse() using the builtin python3.3/ast.py. Full traceback below:

Traceback (most recent call last):

same here, it's because f-string
parser work on python3.3 -> need to be upgrade to 3.6 minimal

Ooops, my bad! I forgot that I added support for pluggable python version a while back, and didn't update the docs.

Check out the PR here and let me know if it's sufficiently clarifying.

tl;dr sublime ships with 3.3. specify a path to python with desired version in your build system via:

"python_executable": "/usr/local/opt/python/bin/python3.7",

it's not help

        }
    ]
}

i still have error f-string

[asfaltboy]

What version is /Users/user/path/automation-services/.venv/bin/python3 run python3 -V ?

If running this "Pytest Runner" build fails it should throw an exception in the console, can you show me the full traceback?

[asfaltboy]

@dc-avasilev have you had any chance to look into the logs?
You could also try to enable SublimeTestPlier's verbose logging by adding "debug": true to your SublimeTestPlier.sublime-settings file. This will output your kwargs, as well as many of the calls in the test resolution flow.
