objective c - LCOV doesn't show some classes -

i have abstact uiviewcontroller has methods test.

@interface abviewcontroller : uiviewcontroller @property (nonatomic, strong) nsmutablearray *testresults; - (void)test; - (void)testfailedwithmessag:(nsstring *)message; @end  @implementation abviewcontroller - (void)testfailedwithmessag:(nsstring *)message {     if(self.testresults == nil)     {         self.testresults = [nsmutablearray array];     }      [self.testresults addobject:message]; } @end 

the basic idea of class test private methods not listed on .h.

the test routines implmented in subclass's "test" method. shown below.

rootviewcontroller subclass of abviewcontroller.

@interface rootviewcontroller () {     uibutton *testbutton; } @end  @implementation rootviewcontroller - (void)viewdidload {     [super viewdidload];      testbutton = [[uibutton alloc] init]; }  - (void)test {     if(testbutton==nil)         [self testfailedwithmessag:@"testbutton nil"]; } @end 

xctest below.

- (void)testrootviewcontroller {     // allocation class instance     rootviewcontroller *testclassinstance = [[rootviewcontroller alloc] init];      // when     [testclassinstance view];      // implement test     [testclassinstance test];      // verify result     xctasserttrue(([[testclassinstance testresults] count] == 0), @"%@", [[testclassinstance testresults] description]); } 

i made several subclasses of abviewcontroller , ran unit test. lcov shows test coverage shows abviewcontroller.

i want see viewcontrollers in project. there way? number of functions not matching functions of viewcontrollers. why?
