And in this (last) case I am unable to confirm an error:
> byTest <- Test %>% group_by(Tests1, Tests2)
>  nest(byTest)
# A tibble: 3 x 3
  Tests1 Tests2             data
   <chr>  <chr>           <list>
1      C      C <tibble [5 x 3]>
2      A      A <tibble [5 x 3]>
3      B      B <tibble [5 x 3]>

After spotting obvious errors in spelling x4 and not being able to reproduce the
fifth example I hope I can be forgiven for not making hte effort to see if any
of your (or my) versions are not up-to-date. I'm going to let you do that:
