XCode 5 Testing symbol “rT” means what?

Question

I have 2 test classes in a XCode 5 project:

ABCDataModelTests.{h,m}

- (void)testAlwaysPassing { ... }

ABCDataModelListColorsTests.m

Answer 1

Deleting derived data didn't help me to get rid of running these tests. So I've created a small category on XCTestCase and it worked:

#import "XCTestCase+TestCaseSwizzling.h"
@import ObjectiveC.runtime;

static NSMutableSet* alreadyRunTests = nil;

@implementation XCTestCase (TestCaseSwizzling)

+ (void)load
{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{

    alreadyRunTests = [NSMutableSet set];

    Class class = [self class];

    SEL originalSelector = @selector(invokeTest);
    SEL swizzledSelector = @selector(swizzledInvokeTest);

    Method originalMethod = class_getInstanceMethod(class, originalSelector);
    Method swizzledMethod = class_getInstanceMethod(class, swizzledSelector);

    method_exchangeImplementations(originalMethod, swizzledMethod);
});
}

- (void)swizzledInvokeTest
{
     NSString* selectorString = NSStringFromSelector(self.invocation.selector);

     if (![alreadyRunTests containsObject:selectorString])
     {
         [alreadyRunTests addObject:selectorString];
         [self swizzledInvokeTest];
     }
 }
