debugging - How to inspect the return value of a function in GDB? -

-

is possible inspect return value of function in gdb assuming return value not assigned variable?

i imagine there better ways it, finish command executes until current stack frame popped off , prints return value -- given program

int fun() {     return 42; }  int main( int argc, char *v[] ) {     fun();     return 0; }

you can debug such --

(gdb) r starting program: /usr/home/hark/a.out   breakpoint 1, fun () @ test.c:2 2               return 42; (gdb) finish run till exit #0  fun () @ test.c:2 main () @ test.c:7 7               return 0; value returned $1 = 42 (gdb)

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...
