在我们的应用程序中使用Firebase时,我有一个相当奇特的场景.在不向项目添加Crashlytics和Fabric的情况下,当我为项目运行单元测试时,会触及以下代码:
@try {
[FIRApp configure];
} @catch (NSException *exception) {
DLog(@"**** Unable to configure Firebase due to exception %@", exception.description);
}

在调试单元测试时,不会引发异常,因此我假设已配置firebase并且所有内容都正常工作.测试通过,没有问题.
然后我非常简单地将Crashlytics with Fabric添加到项目中.我将此作为运行脚本添加到"${PODS_ROOT}/Fabric/run"项目的构建阶段,然后再次运行单元测试.单元测试失败,我得到:
Terminating app due to uncaught exception 'FABException', reason: '[Fabric] Value of Info.plist key "Fabric" must be a NSDictionary.'

作为一个错误,当我运行项目,但一切都很好.只有在运行测试时才会出现此问题.我尝试过以下方法:
"${PODS_ROOT}/Fabric/run"到运行脚本但在单元测试目标上仍然得到相同的错误.我认为Firebase没有正确初始化,这反过来导致Fabric无法正确初始化,从而导致失败.但我不确定如何解决这个问题.任何指导和建议将不胜感激.
