Define test directory by command-line flag

[h2non]

Configuration files are great, specially for branding benefits, but for most small libraries, creating a new file in the repository it's just an unnecessary boilerplate.

Could it would be possible to pass the test root directory via command flag? Or even inferring via file system the proper directory would be great!

I don't know why you have chosen using the __test__ directory by default, which is outside of the community conventions

would also like to know, I keep my tests next to the actual js files they are testing usually.

We won't be adding this as a command line flag, but we will be adding a config option in the future. This is tracked in separate issues. #10 and #637 for example.

@DmitriiAbramov the problem currently is that it only allows you to specify a directory. I'd like to deprecate this option and add a testPattern option where you can also make it a regex, for example to match "test.spec.js". Some people prefer having tests next to their files rather than a __tests__ folder. If you'd like to take this on, that would be great :)
