none of these things in forecast package. in stats:

> m <- stats::holtwinters(co2) > class(m) [1] "holtwinters" > p = predict(m) > pp = stats:::predict.holtwinters(m) > p           jan 1998 365.1079 > pp           jan 1998 365.1079

predict.holtwinters unexported function stats should called on objects holtwinters().

forecast.holtwinters unexported function forecast means need three colons access it. should never have to because should automatically found when run forecast on output holtwinters():

> m <- stats::holtwinters(co2) > forecast(m)          point forecast    lo 80    hi 80    lo 95    hi 95 jan 1998       365.1079 364.7139 365.5019 364.5053 365.7105 feb 1998       365.9664 365.5228 366.4100 365.2879 366.6449 [etc]

same as:

> forecast:::forecast.holtwinters(m)          point forecast    lo 80    hi 80    lo 95    hi 95 jan 1998       365.1079 364.7139 365.5019 364.5053 365.7105 feb 1998       365.9664 365.5228 366.4100 365.2879 366.6449 [etc]

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
