python - What does this stand for? -

-

what '\r' mean? do? have never seen before , giving me headaches. doesnt seem have purpose, since 'a\ra' prints 'aa', not same string 'aa'. im using python 2.6

it's old control character typewriters. means "carriage return". in time, when pressed "enter", going next line, carriage went beginning of line (hence carriage return). computers, different oses made different choices represent new lines. on windows, have "\r\n" (carriage return + new line). on unices, have "\n" (no need carriage return, sort of implied new line). on old mac os, had "\r" only.

nowadays, it's not used except newlines (or don't know other usages).

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
