XCTest 的小技巧

試了一下在一個測試裡，以不同的狀態把其它測試方法跑一遍。

    // alternate what setup done    // full tests in alternated state    NSArray * tests = [FileLibraryTests testInvocations];    for (NSInvocation * inv in tests ) {        NSString * sel = NSStringFromSelector(inv.selector);        if (![sel containsString:@"WithInit"] && ![sel containsString:@"Monitoring"]) {            [inv invokeWithTarget:self];        }    }    //back to normal state

另外，Xcode 6 已經加上了 XCTestExpetation，以後用不著：

    #import <XCTest/XCTestCase+AsynchronousTesting.h>    dispatch_semaphore_t sema = dispatch_semaphore_create(0);    dispatch_after(dispatch_time(0, (int64_t)(0.2 * NSEC_PER_SEC)),         dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0),         ^{            ... dispatch_semaphore_signal(sema); ...        }    );    dispatch_semaphore_wait(sema, dispatch_time(DISPATCH_TIME_NOW, 30*NSEC_PER_SEC));

直接寫

    XCTestExpectation *expectation = [self expectationWithDescription:@"xxx"];    // invoke it in code async executing    ... ^(){        [expectation fulfill];    } ...    [self waitForExpectationsWithTimeout:1 handler:^(NSError *error) {        // cleanup.    }];
