不知道为什么要举报FBSnapshotTestCase image not found while running Xcode test。
我尝试FBSnapshotTestCase在 Target中链接ChartTests，但仍然看到相同的错误。
我不熟悉这个，有人可以帮忙吗？预先感谢。
重现：
从https://github.com/danielgindi/Charts下载项目
导航到项目根目录，
（可选）运行
carthage bootstrap以安装依赖项。该项目有一个依赖检查，所以如果你不运行它，它会在启动测试时运行它。进入
xcodebuild -project 'Charts.xcodeproj' -scheme 'ChartsTests' -configuration 'Debug' -sdk iphonesimulator -destination id='E40B5365-EF82-430D-A767-2A37995CCEE1' 清洁构建测试
目标 id 可以是机器上模拟器的任何 uuid。
然后它报告：
