Summary

Have it so that Gallinago will default to the directory of the script calling the setup method.

Details

I think the logic should be if no outputDir is provided to the setup method, default to directory of the calling script.

Will need to add docs and tests.

[thescientist13]

Just noticed that if both params become optional, if you need to provide setupFiles but not a context directory, you would have to pass both params yourself, e.g.

await runner.setup(null, [ /* ... */ ]);

Maybe setup should take an object instead?

[thescientist13]

Seems like there are some options by tapping into the stackTrace.

If it can be done, I think allowing setup to take an object instead for configuration / params would be worthwhile.
