无助级别中的断言

Question

我有一个测试用例和一个帮助类.在helper类中,我想在这里使用assert:

MainTests.h

#import <SenTestingKit/SenTestingKit.h>

@interface MainTests : SenTestCase

@end

MainTests.m

#import "MainTests.h"
#import "HelperClass.h"

@implementation MainTests

- (void)testExample {
    HelperClass *helperClass = [[HelperClass alloc] init];
    [helperClass fail];
}

@end

HelperClass.h

#import <SenTestingKit/SenTestingKit.h>

@interface HelperClass : SenTestCase

- (void)fail;

@end

HelperClass.m

#import "HelperClass.h"

@implementation HelperClass

- (void)fail {
    STFail(@"This should fail");
}

@end

旁注:我必须使辅助类成为子类,SenTestCase才能访问断言宏.

来自辅助类的断言被忽略.有什么想法吗？如何在辅助类中使用断言？

我今天遇到了同样的问题,并提出了一个适用于我的目的的黑客攻击.进入SenTestCase宏,我注意到他们在帮助器上调用[self ...]但没有触发断言.因此,将源类连接到帮助程序让它为我工作.您的问题类的更改如下所示:

MainTests.h

#import <SenTestingKit/SenTestingKit.h>

@interface MainTests : SenTestCase

@end

MainTests.m

#import "MainTests.h"
#import "HelperClass.h"

@implementation MainTests

- (void)testExample {
    // Changed init call to pass self to helper
    HelperClass *helperClass = [[HelperClass alloc] initFrom:self];
    [helperClass fail];
}

@end

HelperClass.h

#import <SenTestingKit/SenTestingKit.h>

@interface HelperClass : SenTestCase

- (id)initFrom:(SenTestCase *)elsewhere;
- (void)fail;

@property (nonatomic, strong) SenTestCase* from;

@end

HelperClass.m

#import "HelperClass.h"

@implementation HelperClass

@synthesize from;

- (id)initFrom:(SenTestCase *)elsewhere
{
    self = [super init];
    if (self) {
        self.from = elsewhere;
    }
    return self;
}

- (void)fail {
    STFail(@"This should fail");
}

// Override failWithException: to use the source test and not self
- (void) failWithException:(NSException *) anException {
    [self.from failWithException:anException];
}

@end

完全有可能需要额外的覆盖才能获得更高级的功能,但这对我来说非常有用.
