Unit testing of master data - anonymously displayed by code 134

Question

I am setting up unit testing for my main data application. I got confused by a strange problem in a fairly simple test. The error I am getting is:

/Developer/Tools/RunPlatformUnitTests.include:451:0 Test rig '/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.0.sdk/Developer/usr/bin/otest' exited abnormally with code 134 (it may have crashed).

Title for my unit tests:

#import <SenTestingKit/SenTestingKit.h>
#import <UIKit/UIKit.h>
#import <CoreData/CoreData.h>
#import "Unit.h"

@interface UnitLogicTests : SenTestCase {
    NSManagedObjectContext *managedObjectContext;
    NSPersistentStoreCoordinator *persistentStoreCoordinator;
    NSManagedObjectModel *managedObjectModel;
    NSPersistentStore *persistentStore;
}
@end

Implementation:

#import "UnitLogicTests.h"

@implementation UnitLogicTests

#pragma mark Setup and Teardown
- (void)setUp {
    managedObjectModel = [[NSManagedObjectModel mergedModelFromBundles: nil] retain];
    NSLog(@"model: %@", managedObjectModel);
    persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:managedObjectModel];
    persistentStore = [persistentStoreCoordinator addPersistentStoreWithType:NSInMemoryStoreType
                                                               configuration:nil
                                                                         URL:nil
                                                                     options:nil 
                                                                       error:NULL];
    managedObjectContext = [[NSManagedObjectContext alloc] init];
    [managedObjectContext setPersistentStoreCoordinator:persistentStoreCoordinator];
}

- (void)tearDown
{
    [managedObjectContext release];
    managedObjectContext = nil;
    NSError *error = nil;
    STAssertTrue([persistentStoreCoordinator removePersistentStore:persistentStore error:&error], 
                 @"couldn't remove persistent store: %@", error);
    persistentStore = nil;
    [persistentStoreCoordinator release];
    persistentStoreCoordinator = nil;
    [managedObjectModel release];
    managedObjectModel = nil;
}

#pragma mark -
#pragma mark Test Cases
- (void)testThatEnvironmentWorks
{
    STAssertNotNil(persistentStore, @"no persistent store");
}


- (void)testNewUnitDefaults {
    Unit *newUnit = [NSEntityDescription insertNewObjectForEntityForName:@"Unit" 
                                                  inManagedObjectContext:managedObjectContext];
    STAssertEquals(newUnit.floorNumber, 1, @"Default value for new Unit floor number should be 1");

}

@end

If I omit the test - (void)testNewUnitDefaults, then the assembly completes without errors, so something in this last test throws it for a loop. I am new to this, so any help would be greatly appreciated!

Thank.

Answer 1

put the @try .... catch block around your test file.

I think loading the model with

[NSManagedObjectModel mergedModelFromBundles: nil]

It does not work properly

,

+entityForName: could not locate an entity named 'Unit' in this model.

:

    // set according to the identifier in your modeltest Info.plist

    NSString* path = [[NSBundle bundleWithIdentifier:@"com.yourcompany.ModelTest"] 
                                     pathForResource:@"CoreDataUnitTest_DataModel" 
                                              ofType:@"mom"];
    NSURL* modelURL = [NSURL URLWithString:path];
    managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL];

[NSBundle bundleForClass:[self class]]

, unit test

NSBundle * bundle = [NSBundle bundleForClass:[self class]];
managedObjectModel_ = [NSManagedObjectModel mergedModelFromBundles:[NSArray arrayWithObject:bundle]];

   //You can uses this line to figure you what your bundle is actually named

   //xcdatamodel file without an extension
   //Some tutorials will have you use AppName.xcdatamodel others will simply name it
   //DataModel.xcdatamodel.
   //In any event if bothe path and path1 return null then check the
