Objective-C integration testing на примере части RSS читалки

 typedef void (^RSTestCaseAsync)(XCTestExpectation *expectation); ... ... ... - (void)asyncTest:(RSTestCaseAsync)async {     [self asyncTest:async timeout:5.0]; }  - (void)asyncTest:(RSTestCaseAsync)async timeout:(NSTimeInterval)timeout {     XCTestExpectation *expectation = [self expectationWithDescription:@"block not call"];     XCTAssertNotNil(async, @"don't send async block!");     async(expectation);     [self waitForExpectationsWithTimeout:timeout handler:nil]; } 

Основной смысл данного класса — обеспечение информации о падении внутри метода setUp. Ведь этот метод вызывается перед выполнением любого теста и падение здесь означает провал последующего теста. Однако сам метод не является тестом и падение в нем не запишет ошибку в таблицу тестов. Поэтому в данном классе имеется тест testInitAfterSetUp. Данный тест выполнится успешно и будет вызван (в произвольном порядке) у каждого дочернего класса при успешном выполнении метода setUp. Провал этого теста сигнализирует о падении внутри метода setUp.

Если пишется для своего сервера, то можно написать 1 тест на получение RSS с сервера и исключенить из списка тестирования (но запускать руками — все ли отлично после очередной фитчи у вас или на сервере?). Для этого достаточно найти нужный тест в списке тестов и выключить.
