Xcode中的XCTest和异步测试 [英] XCTest and asynchronous testing in Xcode 6

问题描述

因此Apple在Xcode 6的发行说明中说我们现在可以直接使用XCTest进行异步测试。

So Apple said in the release note of Xcode 6 that we can now do asynchronous testing directly with XCTest.

任何人都知道如何使用Xcode 6 Beta 3（使用Objective-C或Swift）？我不想要已知的信号量方法，而是新的Apple方式。

Anyone knows how to do it using Xcode 6 Beta 3 (Using objective-C or Swift)? I don't want the known semaphore method, but the new Apple way.

我搜索了发布的笔记以及更多，但我什么也没找到。 XCTest标头也不是非常明确。

I searched into the released note and more but I found nothing. The XCTest header is not very explicit either.

推荐答案

会话视频很完美，基本上你想做这样的事情

The sessions video is perfect, basically you want to do something like this

func testFetchNews() {
    let expectation = self.expectationWithDescription("fetch posts")

    Post.fetch(.Top, completion: {(posts: [Post]!, error: Fetcher.ResponseError!) in
        XCTAssert(true, "Pass")
        expectation.fulfill()
    })

    self.waitForExpectationsWithTimeout(5.0, handler: nil)
}
