# (c) cavaliba.com - test / FieldDatetime - input without seconds

"""
The edit form uses the native <input type="datetime-local"> picker. Even with
step="1" the browser may hide the seconds box (platform dependent), and a user
can always type "10:20" by hand - in both cases the POSTed value is
'YYYY-MM-DDThh:mm'.

Before "%Y-%m-%dT%H:%M" joined ACCEPTED_FORMATS, _normalize_datetime() returned
None for that and merge_request() silently wiped the field. These tests pin the
no-seconds variant: accepted, seconds defaulting to 00, and still rejecting the
genuinely malformed input around it.
