check_type works

Code
  check_type(x_var, is.character)
Condition
  Error:
  ! `x_var` must be 'character', not 'integer'.

Code
  check_type(x_var, is.character, "symbolic")
Condition
  Error:
  ! `x_var` must be 'symbolic', not 'integer'.

Code
  check_type(x_df, is.logical)
Condition
  Error:
  ! `x_df` must be 'logical', not 'data.frame'.

check_type allows custom name for x

Code
  check_type(input, is.numeric, x_name = "aaa")
Condition
  Error:
  ! `aaa` must be 'numeric', not 'character'.

check_type allows extra arguments for predicate

Code
  check_type(1, is_geq, min_val = 2)
Condition
  Error:
  ! `1` must be 'geq', not 'double'.

check_type allows formula predicate

Code
  check_type("a", ~ is.numeric(.))
Condition
  Error:
  ! `"a"` must be '~is.numeric(.)', not 'character'.

hypothesize errors out when x isn't a dataframe

Code
  hypothesize(c(1, 2, 3), null = "point")
Condition
  Error in `hypothesize()`:
  ! x must be a data.frame or tibble
