stabilize_df() respects .allow_null (#142)

Code
  (expect_pkg_error_classes(stabilize_df(NULL, .allow_null = FALSE), "stbl",
  "bad_null"))
Output
  <error/stbl-error-bad_null>
  Error:
  ! `NULL` must not be <NULL>.

Code
  (expect_pkg_error_classes(wrapped_stabilize_df(NULL, .allow_null = FALSE),
  "stbl", "bad_null"))
Output
  <error/stbl-error-bad_null>
  Error in `wrapped_stabilize_df()`:
  ! `val` must not be <NULL>.

stabilize_df() errors for non-coercible input (#142)

Code
  (expect_pkg_error_classes(stabilize_df("not a data frame"), "stbl", "coerce",
  "data.frame"))
Output
  <error/stbl-error-coerce-data.frame>
  Error:
  ! Can't coerce `"not a data frame"` <character> to <data.frame>.

Code
  (expect_pkg_error_classes(wrapped_stabilize_df("not a data frame"), "stbl",
  "coerce", "data.frame"))
Output
  <error/stbl-error-coerce-data.frame>
  Error in `wrapped_stabilize_df()`:
  ! Can't coerce `val` <character> to <data.frame>.

stabilize_df() errors when required column is missing (#142)

Code
  (expect_pkg_error_classes(stabilize_df(data.frame(foo = "a"), name = specify_chr_scalar()),
  "stbl", "missing_element"))
Output
  <error/stbl-error-missing_element>
  Error:
  ! `data.frame(foo = "a")` must contain element "name".

stabilize_df() errors informatively when column fails validation (#142)

Code
  (expect_pkg_error_classes(stabilize_df(data.frame(count = "not-an-int"), count = specify_int_scalar()),
  "stbl", "incompatible_type"))
Output
  <error/stbl-error-incompatible_type>
  Error:
  ! `data.frame(count = "not-an-int")[["count"]]` <character> must be coercible to <integer>
  x Can't convert some values due to incompatible values.
  * Locations: 1

stabilize_df() errors on extra columns by default (#142)

Code
  (expect_pkg_error_classes(stabilize_df(data.frame(a = 1L, b = 2L), a = specify_int_scalar()),
  "stbl", "bad_named"))
Output
  <error/stbl-error-bad_named>
  Error:
  ! `data.frame(a = 1L, b = 2L)` must not contain extra named elements.
  x Extra element: "b"

stabilize_df() validates extra columns with .extra_cols (#142)

Code
  (expect_pkg_error_classes(stabilize_df(data.frame(a = 1L, b = "not-int"), a = specify_int_scalar(),
  .extra_cols = specify_int_scalar()), "stbl", "incompatible_type"))
Output
  <error/stbl-error-incompatible_type>
  Error:
  ! `data.frame(a = 1L, b = "not-int")[["b"]]` <character> must be coercible to <integer>
  x Can't convert some values due to incompatible values.
  * Locations: 1

stabilize_df() enforces .min_rows (snapshot) (#142)

Code
  (expect_pkg_error_classes(stabilize_df(mtcars[0, ], .min_rows = 1, .extra_cols = stabilize_present),
  "stbl", "too_few_rows"))
Output
  <error/stbl-error-too_few_rows>
  Error:
  ! `mtcars[0, ]` must have at least 1 row.
  x 0 is too few.

stabilize_df() enforces .max_rows (snapshot) (#142)

Code
  (expect_pkg_error_classes(stabilize_df(mtcars, .max_rows = 5, .extra_cols = stabilize_present),
  "stbl", "too_many_rows"))
Output
  <error/stbl-error-too_many_rows>
  Error:
  ! `mtcars` must have at most 5 rows.
  x 32 is too many.

stabilize_df() enforces .col_names (snapshot) (#142)

Code
  (expect_pkg_error_classes(stabilize_df(data.frame(a = 1L), .col_names = c("a",
    "b"), .extra_cols = stabilize_present), "stbl", "missing_cols"))
Output
  <error/stbl-error-missing_cols>
  Error:
  ! `data.frame(a = 1L)` must contain column "b".

stabilize_df() with unnamed specs errors informatively (#142)

Code
  (expect_pkg_error_classes(stabilize_df(data.frame(a = 1L), specify_int_scalar()),
  "stbl", "unnamed_spec"))
Output
  <error/stbl-error-unnamed_spec>
  Error:
  ! All elements passed via `...` must be named.
  i Each name corresponds to a required element in the list.
