测试块是否使用 OCMock 执行

Question

我正在使用 OCMock 和 XCTest 来测试将块作为参数的方法。我想测试块是否在成功和失败时执行。下面的代码是否足以测试该块是否已执行？

__block  BOOL didExecute = NO;

[testSubject performActionWithBlock:^(id result, NSError *error) {
    didExecute = YES;
}];

XCTAssertTrue(didExecute);

Answer 1

如果要检查一个块是否已经执行，Xcode6中最好的方法是使用XCTestExpectation:

// Create an expectation with whatever description you want
// The description will be displayed in the test report if the expectation causes the test to fail
XCTestExpectation *blockExpectation = [self expectationWithDescription:@"Block Expectation"];

[testSubject performActionWithBlock:^(id result, NSError *error) {
    // Inside the block, fulfill the expectation
    [blockExpectation fulfill];
}];

// The timeout should be the max amount of time you want the test to wait
[self waitForExpectationsWithTimeout:1.0 handler:nil];
