--tests-dir for multiple directories

[hirowatari]

I would like for --test-dirs to be used multiple times similar to how on phpunit you may have multiple test directories. Alternatively, it might be wise for steward to warn when that param it's used multiple times, that only the final time will be used.

Thanks a lot for this great tool.

Hi, we use Symofony Console, which handles the parameter parsing, so there is nothing we should do about warning user if parameters are improperly used, as this is not done in steward.

However Symfony Console support array parameters. So this is definitely possible to implement, however no plans for this right now. But I would accept PR regarding this (however this must be handled no only in CLI params, but also in steward.yaml config file).

I would like this functionality, I am up for creating pull request for it if I can find the time.
