role is validated

Code
  update_role_requirements(rec, 1)
Condition
  Error in `update_role_requirements()`:
  ! Can't convert `role` <double> to <character>.

Code
  update_role_requirements(rec, c("x", "y"))
Condition
  Error in `update_role_requirements()`:
  ! `role` must have size 1, not size 2.

can't update a role that doesn't exist

Code
  update_role_requirements(rec, "id", bake = FALSE)
Condition
  Error in `update_role_requirements()`:
  x `role` must be a preexisting role in the recipe.
  i "id" is not a preexisting role.

can't update the predictor role

Code
  update_role_requirements(rec, "predictor", bake = FALSE)
Condition
  Error in `update_role_requirements()`:
  x Can't update the `bake` requirement of the "predictor" role.
  i The "predictor" role is always required at `bake()` time.

can't update the outcome role

Code
  update_role_requirements(rec, "outcome", bake = FALSE)
Condition
  Error in `update_role_requirements()`:
  x Can't update the `bake` requirement of the "outcome" role.
  i The "outcome" role is never required at `bake()` time.

will still error if a step actually used a role that set bake = FALSE

Code
  rec <- prep(rec, df)
Condition
  Warning:
  Column `x` returned NaN, because variance cannot be calculated and scaling cannot be used. Consider avoiding `Inf` or `-Inf` values and/or setting `na_rm = TRUE` before normalizing.

Code
  bake(rec, df)
Condition
  Error in `step_scale()`:
  ! The following required column is missing from `new_data`: x.

can update bake requirements after prepping

Code
  bake(rec, df)
Condition
  Error in `bake()`:
  x The following required columns are missing from `new_data`: `x`.
  i These columns have one of the following roles, which are required at `bake()` time: `id`.
  i If these roles are not required at `bake()` time, use `update_role_requirements(role = "your_role", bake = FALSE)`.

errors on missing 'predictor's

Code
  bake(rec, df)
Condition
  Error in `bake()`:
  x The following required columns are missing from `new_data`: `x`, `z`, and `w`.
  i These columns have one of the following roles, which are required at `bake()` time: `predictor`.

can request that case weights be required

Code
  bake(rec, df)
Condition
  Error in `bake()`:
  x The following required columns are missing from `new_data`: `w`.
  i These columns have one of the following roles, which are required at `bake()` time: `case_weights`.
  i If these roles are not required at `bake()` time, use `update_role_requirements(role = "your_role", bake = FALSE)`.

nonstandard roles are required by default

Code
  bake(rec, df)
Condition
  Error in `bake()`:
  x The following required columns are missing from `new_data`: `x` and `z`.
  i These columns have one of the following roles, which are required at `bake()` time: `id`.
  i If these roles are not required at `bake()` time, use `update_role_requirements(role = "your_role", bake = FALSE)`.

unspecified roles are required by default

Code
  bake(rec, df)
Condition
  Error in `bake()`:
  x The following required columns are missing from `new_data`: `x` and `z`.
  i These columns have one of the following roles, which are required at `bake()` time: `NA`.
  i If these roles are not required at `bake()` time, use `update_role_requirements(role = "your_role", bake = FALSE)`.

can bake on an old recipe that doesn't have requirements

Code
  bake(rec, df)
Condition
  Error in `bake()`:
  x The following required columns are missing from `new_data`: `x`.
  i These columns have one of the following roles, which are required at `bake()` time: `predictor`.

can bake on an old recipe that doesn't have requirements$bake

Code
  bake(rec, df)
Condition
  Error in `bake()`:
  x The following required columns are missing from `new_data`: `x`.
  i These columns have one of the following roles, which are required at `bake()` time: `predictor`.

can update the role requirements of an old recipe

Code
  bake(rec, df)
Condition
  Error in `bake()`:
  x The following required columns are missing from `new_data`: `x`.
  i These columns have one of the following roles, which are required at `bake()` time: `id`.
  i If these roles are not required at `bake()` time, use `update_role_requirements(role = "your_role", bake = FALSE)`.

bake is validated

Code
  update_role_requirements(rec, "id", bake = 1)
Condition
  Error in `update_role_requirements()`:
  ! `bake` must be `TRUE` or `FALSE`, not the number 1.

Code
  update_role_requirements(rec, "id", bake = c(TRUE, FALSE))
Condition
  Error in `update_role_requirements()`:
  ! `bake` must be `TRUE` or `FALSE`, not a logical vector.

Code
  update_role_requirements(rec, "id", bake = NA)
Condition
  Error in `update_role_requirements()`:
  ! `bake` must be `TRUE` or `FALSE`, not `NA`.
