makefile - Getting Quiet Make to echo command lines on error -

-

i have makefile building many c files long long command lines , we've cleaned output having rules such as:

.c${mt}.doj:          @echo "compiling $<";\          $(compiler) $(copts) -c -o $@ $<

now great @ suppresses compilation line being emitted. when error, error message, no command line. can think of "neat" way emit command line? can think of doing echoing file , have higher level make catch error , cat file. hacky know.

tested , worked (gnu make in linux):

.c${mt}.doj:      @echo "compiling $<";\           $(compiler) $(copts) -c -o $@ $<  \           || echo "error in command: $(compiler) $(copts) -c -o $@ $<" \           && false

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...
