iphone - Testing NSWidowController using OCMock -

-

i've been trying come a way unit test applicationdidfinishlaunching delegate using ocmock. nswindowcontroller instantiated here , i'd test it. here's test code:

id mockwindowcontroller = [ocmockobject nicemockforclass:[urltimerwindowcontroller class]]; [[mockwindowcontroller expect] showwindow:self]; nsuinteger preretaincount = [mockwindowcontroller retaincount];  [appdelegate applicationdidfinishlaunching:nil];  [mockwindowcontroller verify];

when run test, error:

"ocmockobject[urltimerwindowcontroller]: expected method not invoked: showwindow:-[urltimerappdelegatetests testapplicationdidfinishlaunching]"

the log gives more detail:

"test case '-[urltimerappdelegatetests testapplicationdidfinishlaunching]' started. 2011-04-11 08:36:57.558 otest-x86_64[3868:903] -[urltimerwindowcontroller loadwindow]: failed load window nib file 'timerwindow'. unknown.m:0: error: -[urltimerappdelegatetests testapplicationdidfinishlaunching] : ocmockobject[urltimerwindowcontroller]: expected method not invoked: showwindow:-[urltimerappdelegatetests testapplicationdidfinishlaunching] test case '-[urltimerappdelegatetests testapplicationdidfinishlaunching]' failed (0.005 seconds). "

so see nib fails load. ok, how make load while unit testing or somehow mock load? i've looked @ ocmock docs, chris hanson's tips on unit testing , few other resources, including whereismymac source code behave in similar fashion. application instantiating window controller this:

self.urltimerwindowcontroller = [[urltimerwindowcontroller alloc] init]; [self.urltimerwindowcontroller showwindow:self];

any tips appreciated.

the problem test mockwindowcontroller , urltimerwindowcontroller not same object. , self in test not same self in class under test. doesn't matter nib doesn't load in case.

you can't mock object when it's instantiated inside method want test. 1 alternative instantiate object in 1 method, pass method finishes setup. can test setup method. example:

-(void)applicationdidfinishlaunching:(nsnotification *)anotification {     self.urltimerwindowcontroller = [[urltimerwindowcontroller alloc] init];     [self setuptimerwindow:urltimerwindowcontroller]; }  -(void)setuptimerwindow:(urltimerwindowcontroller *)controller {     [controller showwindow:self]; }

then, test setuptimerwindow::

-(void)testsetuptimerwindowshouldshowwindow {     urltimerappdelegate *appdelegate = [[urltimerappdelegate alloc] init];      id mockwindowcontroller = [ocmockobject nicemockforclass:[urltimerwindowcontroller class]];     [[mockwindowcontroller expect] showwindow:appdelegate]; // seems weird. showwindow take app delegate parameter?      [appdelegate setuptimerwindow:mockwindowcontroller];      [mockwindowcontroller verify];     [appdelegate release]; }

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
