      Specific to `test_sample*_axis_1` tests.
      A pytest fixture of valid `random_state` parameter pairs for pandas
      and cudf. Valid parameter combinations, and what to check for each pair
      are listed below:
  
      pandas:   None,   seed(int),  np.random.RandomState
      cudf:     None,   seed(int),  np.random.RandomState
      ------
      check:    shape,  shape,      exact result
  
      Each column above stands for one valid parameter combination and check.
