Xcode.添加到测试目标的图像资源不会复制到测试包中 [英] Xcode. Image resources added to a test target are not copied into the tests bundle

问题描述

我为 UIImage 类编写了一些扩展，并希望通过单元测试覆盖它.我添加了一些图像来测试目标并检查它是否出现在 Copy Bundle Resources 列表中.

I wrote some extension to UIImage class and want to cover it by Unit Tests. I added some image to test target and checked that it presents in the Copy Bundle Resources list.

在测试代码中，我使用了一个模型对象，它为我提供了测试数据.

In the test code I use a model object which pvovides me test data.

class TestConstants {
    private static var bundle: Bundle {
        return Bundle(for: UIImageExtensionsTests.self)
    }
    private static var birdImageURL: URL {
        let path = self.bundle.url(forResource: "birds", withExtension: "png")
        return path!
    }
    static var birdImageData: Data {
        return try! Data(contentsOf: self.birdImageURL)
    }
}

不幸的是 birds.png 图像不在测试包中，但存在另一个资源 drm.txt.我有点困惑，这是 Xcode 中的错误吗?顺便说一下，我下载了 Xcode 9.4 beta 并且有相同的行为 - 图像不会复制到测试包中.

Unfortunately birds.png image is not located in test bundle, but another resource drm.txt presents. I'm a bit confused is it the bug in Xcode? By the way I downloaded Xcode 9.4 beta and there are the same behavior - images do not copy into the test bundle.

#UPDATE:

UIImageExtensionsTests 是与 drm.txt 和 birds.png 文件在同一目标中的测试类

UIImageExtensionsTests is a test class presents in the same target with drm.txt and birds.png file

推荐答案

我的错是我没有仔细阅读日志.这个问题发生在互联网上的错误"形象.Xcode 无法处理图像，因此它没有将其复制到测试包中.

My bad that I didn't read log carefully. The issue was happen with "wrong" image founded in internet. Xcode couldn't proceed image, so it didn't copy it to test bundle.

阅读时/Users/igork/developer/gitlab/ios.gym-master/GymMasterTests/Resources/birds.pngpngcrush 捕获 libpng 错误:不是 PNG 文件..

While reading /Users/igork/developer/gitlab/ios.gym-master/GymMasterTests/Resources/birds.png pngcrush caught libpng error: Not a PNG file..

并且此错误不会导致构建和运行目标失败.所以在我的情况下，测试开始了:(

And this error doesn't fail building and running the target. So in my case the tests were starting :(
