Instance Method Details

#assert_all_mailer_actions_have_previews(except: []) ⇒ Object

Opt-in companion to ‘generate_preview_tests`. That method only snapshot-tests the previews that EXIST; this asserts every mailer ACTION has a matching preview, so a new mailer/action can’t silently ship with no preview.

‘except:` allowlists “Mailer#action” strings that intentionally have no preview — document the reason at the call site.
