reactabular-select - Add basic tests

Test plan:

byArrowKeys:

• Up arrow pressed, no selectedRowIndex provided -> nothing should happen.
• Down arrow pressed, no selectedRowIndex provided -> nothing should happen.
• Up arrow pressed, selectedRowIndex provided and it’s larger than zero -> onSelectRow should get called with selectedRowIndex - 1.
• Down arrow pressed, no selectedRowIndex provided and it’s smaller than rows length - 1 -> onSelectRow should get called with selectedRowIndex + 1.

selectRow:

• Assuming rows contains selected flags and isSelected does not match any, all selected flags should become false.
• If isSelected matches a row, the resulting rows should have matching ones with the selected flag set as true. selectRow should also return selectedRows within an array (currently it returns just the last selectedRow!).

Moved to selectabular. Closing.

I’ll probably remove selection bits from reactabular in the next major release and rewrite documentation accordingly.

Yup I was referring exactly at that basic config: jest + babel + eslint. I’m usually more on the side of ava/tape for tests, must confess I’m quite liking Jest 😃
