How to cause Xcode 5 unit tests to fail early?

Question

I'm running SenTestKit unit tests in Xcode 5 (actually, they're integration tests with KIF 2, but it amounts to the same thing). These tests take a long time to run. Is there a way to have the entire test suite fail with the first test failure?

Answer 1

You can abort testing on the first SetTestKit test failure by calling [self raiseAfterFailure] at the start of each test case. However, this does not work for KIF 2.

I ended up subclassing SenTestObserver like so:

@interface TestObserver : SenTestObserver
@end

@implementation TestObserver

+ (void)load {
    [[NSUserDefaults standardUserDefaults] setValue:@"SenTestLog,TestObserver"
                                             forKey:SenTestObserverClassKey];
}

+ (void)testCaseDidFail:(NSNotification *)notification {
    // Fail fast
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        exit(1);
    });
}

@end

Edited to add dispatch_after so that there's time to capture test output before terminating the test suite.
