注意：这个问题是相关的，但那里给出的答案并没有解决我的问题：XC Testing Framework iOS(XCode 6.1) Test session exited(80) without check in
我有现有的 iOS 代码，我想开始使用我的 Xcode 6.3 编写 XCTest 案例。我通过单击测试导航器中的 + 来创建一个测试目标。为我创建了一个测试目标，包括一个包含单元测试的文件 Tests。
测试在测试导航器中开始显示为灰色（我无法单击 cmd+T）。
问题 1：如何启用测试？
编辑：此屏幕截图中描述了答案：https ://www.evernote.com/shard/s4/sh/6a5ca990-d723-46ee-bf77-2cf0ff4e70b2/1a62c472fbbeeffa595fcecd4a9fbbf7 ，我在这里找到：将单元测试添加到已经存在的项目？
在我的项目设置中，我的生产目标（旧版）
具有以下设置：以及我的测试目标（自动生成）的以下设置：
如果我通过单击 Test Navigator 中的 Play 按钮手动运行我的测试，我会收到以下大量错误消息。

问题 2：我还必须检查/更改哪些设置才能运行测试？
编辑将 arm64 添加到生产目标有效架构解决了这个特定错误。添加这样有危险吗？
