pytest watch seems to fail when pyproject.toml is used as a config file

[max-sixty]

When pytest config is stored in pyproject.toml:

Traceback (most recent call last):
  File "/Users/maximilian/Library/Caches/pypoetry/virtualenvs/n-cyukv0jK-py3.8/bin/ptw", line 8, in <module>
    sys.exit(main())

    if not merge_config(args, pytest_args, verbose=args['--verbose']):

    raise e
configparser.ParsingError: Source contains parsing errors: '/Users/maximilian/workspace/n/pyproject.toml'
	[line 59]: ']\n'

This works when the pytest config in pyproject.toml is removed

any updates?

Same problem here.

[Jufik]

Faced the same issue and investigated my pyproject.toml

anytime you have

variable=[
    ....
]

I change to (note the 4 spaces)

variable=[
    ....
    ]

PTW works like a charm

folks how can one simple mortal format a file in a way where this does not happen but you keep your pytest config on your pyproject.toml?

[abdul-hamid-achik]

btw moving pytest configuration form pyproject.toml to pytest.ini did the trick but I would prefer to not have extra config files

[ketozhang]

As we can see in the trace, this tool only implements parsing using the configparser — it assumes pytest config are only ini files. What I see the next steps are for pytest-watch to stop bootstrapping off of pytest.config and start handling their own parsing of pytest.ini, pyproject.toml, and any legacy config files.

@joeyespo Any interest of accepting contributions to this?
