c# - Change application settings from codedUI test -

is there anyway change application/user settings in application under test in codedui test? if how?

particularly user settings useful able control environment of test regardless of changes have made locally settings.

no cannot access variables in application under test directly. if controls accessed under coded ui test accessbility option. 1 way modify settings have them set in config/xml file , have coded ui test case method modify xml file. assumes application uses user settings in xml file dynamically. if not should not hard change so, if can extract settings xml file.
