objective c - Logic Test vs Application Test - Conflicting Results -


i have 2 test targets in project, logic test (modellogictests) , application test (myapptests). have 1 class use in both test models built json objects.

the test case follows:

// modellogictests.m @interface mymodellogictests : xctestcase  @property nsmanagedobjectcontext *context; @property nsmanagedobjectmodel *model; @property nspersistentstorecoordinator *store; @property nsbundle *bundle;  @end  @implementation mymodellogictests  - (void)setup {     [super setup];     nsbundle *bundle = [nsbundle bundleforclass:[self class]];     nsarray *bundles = @[ bundle ];     self.bundle = bundle;      self.model = [nsmanagedobjectmodel mergedmodelfrombundles:bundles];     xctassertnotnil( self.model, @"managed object model \'nil.\'" );      self.store = [[nspersistentstorecoordinator alloc] initwithmanagedobjectmodel:self.model];     xctasserttrue( self.store, @"persistent store coordinator did not initialize properly." );      nserror *storeerror = 0;     nspersistentstore *tempstore = [self.store addpersistentstorewithtype:nsinmemorystoretype configuration:nil url:nil options:nil error:&storeerror];     xctassertnil( storeerror, @"error: %@", storeerror.debugdescription );     xctassertnotnil( tempstore, @"\'tempstore\' should not \'nil.'" );       self.context = [[nsmanagedobjectcontext alloc] init];     self.context.persistentstorecoordinator = self.store;     xctassert( self.context, @"nsmanagedobjectcontext did not initlaize." );     xctassert(               self.context.persistentstorecoordinator,               @"context's persistent store did not stored." ); }  - (void)testbuildsimplemodel {     nsurl *path = [self.bundle urlforresource:@"simplemodel" withextension:@"json"];     xctasserttrue(                   [path iskindofclass:[nsurl class]],                   @"\'path\' instance of \'%@.\'", [path class] );      nsdata *jsondata = [[nsdata alloc] initwithcontentsofurl:path];     xctasserttrue( [jsondata iskindofclass:[nsdata class]], @"" );      nserror *jsonerror = 0;     nsdictionary *json_dict = [nsjsonserialization jsonobjectwithdata:jsondata options:0 error:&jsonerror];     xctassertnil( jsonerror, @"json error: %@", jsonerror.description );     xctasserttrue( [json_dict iskindofclass:[nsdictionary class]], @"" );     xctassertequalwithaccuracy(json_dict.count, (nsuinteger)4, 0, @"" );      myspot *spot = [myspot buildmyspotfromjson:json_dict context:self.context];     xctassertnotnil( spot, @"" );      // problem test here when running application test     xctasserttrue(                   [spot iskindofclass:[myspot class]],                   @"is instance of \'%@.\'",                   nsstringfromclass([spot class]) );      nserror *saveerror = 0;     xctasserttrue( [self.context save:&saveerror], @"save error: %@", saveerror.debugdescription );      xctassertequalobjects( spot.name, @"montreal", @"" );     xctassertequalwithaccuracy(spot.latitude.floatvalue, (cgfloat)45.5, 0.0, @"" );     xctassertequalwithaccuracy(spot.longitude.floatvalue, (cgfloat)-73.566667, 0, @"" );     xctassertequalwithaccuracy(                                spot.status.integervalue,                                (myspotstatus)myspotstatusopen,                                0,                                @"should \'open.\'" ); }

the issue this, running logic, tests pass expected. under application test, following test fails:

xctasserttrue(     [spot iskindofclass:[myspot class]],     @"is instance of \'%@.\'",     nsstringfromclass([spot class]) );

and output is:

-[mymodellogictests testbuildsimplemodel] : (([spot iskindofclass:[myspot class]]) true) failed - instance of 'myspot.'

i have double checked resource files, model, , source files, have been added necessary targets.

why failed test (as above), when spot instance of myspot?

update:

as suggested, added:

nslog( @"instance class: %p, class: %p", [spot class] , [myspot class] )  // logic test output instance class: 0x5a178ac, class: 0x5a178ac  // app test output instance class: 0x6fa24, class: 0x9ead2cc

so updated question is, why difference between application tests , logic test?
