FirebaseApp.configure()崩溃了单元测试目标

Question

我遇到了一个奇怪的问题,FirebaseApp.configure()调用导致我的应用程序立即崩溃我的单元测试目标.它对我的标准版本运行良好.

任何想法为什么会这样？

bc ++ abi.dylib:以NSException类型的未捕获异常终止

在崩溃之前,我还看到了大量的日志条目,如:

objc[14289]: Class RCNKeyValue is implemented in both /Users/sammcneilly/Library/Developer/CoreSimulator/Devices/E62EC87E-0B07-4A83-A165-819E693AEB87/data/Containers/Bundle/Application/6C3F993F-4CEB-462F-9257-0F3C8E088BC0/Avalanche.app/Avalanche (0x10f7bdd50) and /Users/sammcneilly/Library/Developer/Xcode/DerivedData/Avalanche-ewiqmxxekhpknrhhfuyljlekgzat/Build/Products/Development-iphonesimulator/Avalanche.app/PlugIns/Avalanche Tests.xctest/Avalanche Tests (0x129e075d8). One of the two will be used. Which one is undefined.

我已经通过CocoaPods安装了Firebase和Firebase/Crashlytics.我不确定这是否与Xcode 9.3有关 - 这是在两个单独的项目中发生的,我相当确定它以前没有发生在旧项目中.

我打印出了包内容,GoogleService-Info.plist文件似乎就在那里.

任何帮助将非常感激!

Answer 1

好的，这可能是由于Pod文件配置错误引起的。我的主要目标和单元测试目标已配置为使用以下Pod：

pod 'Crashlytics', '~> 3.10.1'
pod 'Fabric', '~> 1.7.6'
pod 'Firebase/Core', '~> 4.8'
pod 'FirebaseRemoteConfig', '~> 2.1'

仅移除测试目标的其他Firebase吊舱（除外Firebase/Core），然后pod install再次运行是有帮助的。

我不太确定为什么这样做，所以如果有人可以向我解释这一点，将不胜感激。

生成"${PODS_ROOT}/Fabric/run"阶段脚本已在我的主要目标上配置，如Google文档中所述：https : //firebase.google.com/docs/crashlytics/get-started，并将其添加到测试目标也无济于事...

感谢大家的投入，但是将Fabric详细信息手动添加到Info.plist文件中只会导致生成错误。我相信Firebase会自动处理此步骤。

运行 XCTest 时我们也遇到了同样的崩溃。我们使用以下方法来解决它。

        if NSClassFromString("XCTest") != nil {
            return true
        } else {
            FirebaseApp.configure()
        }
