iPhone UnitTesting UITextField value and otest error 133

Are UITextFields not meant to be part of the LogicTests and instead part of the ApplicationTest target?

I have a factory class that is responsible for creating and returning an (iPhone) UITextField and I'm trying to unit test it. It is part of my Logic Test target and when I try to build and run the tests, I get a build error about:

/Developer/Tools/RunPlatformUnitTests.include:451:0 Test rig '/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.2.sdk/ 'Developer/usr/bin/otest' exited abnormally with code 133 (it may have crashed).

In the build window, this points to the following line in: "RunPlatformUnitTests.include"

RPUTIFail ${LINENO} "Test rig '${TEST_RIG}' exited abnormally with code ${TEST_RIG_RESULT} (it may have crashed)."

My unit test looks like this:

#import <SenTestingKit/SenTestingKit.h>
#import <UIKit/UIKit.h>

// Test-subject headers.
#import "TextFieldFactory.h"

@interface TextFieldFactoryTests : SenTestCase {    

}
@end

@implementation TextFieldFactoryTests

#pragma mark Test Setup/teardown
- (void) setUp {
    NSLog(@"%@ setUp", self.name);      
}

- (void) tearDown {
    NSLog(@"%@ tearDown", self.name);
}

#pragma mark Tests
- (void) testUITextField_NotASecureField
{
    NSLog(@"%@ start", self.name);   
    UITextField *textField = [TextFieldFactory createTextField:YES];    
    NSLog(@"%@ end", self.name); 
}

The class I'm trying to test:

// Header file
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface TextFieldFactory : NSObject {

}

+(UITextField *)createTextField:(BOOL)isSecureField;

@end

// Implementation file
#import "TextFieldFactory.h"

@implementation TextFieldFactory

+(UITextField *)createTextField:(BOOL)isSecureField                   
{
    // x,y,z,w are constants declared else where   
    UITextField *textField = [[[UITextField alloc] 
            initWithFrame:CGRectMake(x, y, z, w)] 
            autorelease];

    // some initia开发者_开发技巧lization code

    return textField;   
}

@end

Why does instantiating a UIFont in an iphone unit test cause a crash?

Apparently, you are not supposed to include UITextField for your logic tests but move them into your application tests.

So I have the same problem too.....any solutions?

What i do to resolve it is create a DummyUITextField class and inject that into my classes that need a UITextField. (its like a mock, but mock would be wrong terminology).

@interface DummyUITextField : UIView {

NSString *text;

}

@property (nonatomic, retain) NSString *text;

@end

You can then add any other methods you need to this class.

However, if the code you're testing creates it's own UITextField's (instead of using Interface Builder), then you're going to have to find another solution.
