问题描述

我们已经开始使用Firebase远程配置进行AB测试.已经过去了24个小时，当应该为每个变体分配成千上万的DAU时，它会显示"Total Users:0".

We've started an AB test using Firebase remote config. It's been over 24 hours, and it's showing "Total Users: 0" when there should have been tens of thousands of DAUs assigned to each variant.

数据输入需要多长时间?
有什么方法可以判断它是否正在运行?
如果它保持为零，潜在的根本原因是什么?为什么没有将人员分配给测试变体?

推荐答案

找到了解决方案.有一些愚蠢的错误，但很容易错过，因为远程配置无需修复就可以正常工作.

Found the solution. A few dumb mistakes, but they are easy to miss because the remote config works fine without fixing them.

确保将Firebase SDK/pod升级到4.5或更高版本.早期版本具有相同的API，但不会提供AB测试值(仅远程配置值)
确保在调用 FIRApp配置
在运送至应用商店之前，请先验证AB测试草案是否有效.这样做的一些技巧:
- 传递0使其在 fetchWithExpirationDuration 中失效，因此每次被强制获取新值(默认情况下将缓存).
- 以调试模式设置远程配置(以下代码)
- Google关于如何验证的说明: https://firebase.google.com/docs/remote-config/abtest-config#validate_your_experiment_on_a_test_device
- Ensure you upgrade Firebase SDK/pod to 4.5 or later. Earlier versions have an identical API but won't serve AB tests values (only remote config values)
- Ensure you call fetchWithExpirationDuration AFTER you call FIRApp configure
- Verify a draft AB test is working before shipping to app store. Some tips for doing this:
  - Pass 0 for expiration in fetchWithExpirationDuration when in debug mode so it's forced to fetch new values every time (it will cache by default).
  - Setup remote config in debug mode (code below)
  - Instructions from Google on how to verify: https://firebase.google.com/docs/remote-config/abtest-config#validate_your_experiment_on_a_test_device
```
#ifdef DEBUG
    FIRRemoteConfigSettings* remoteConfigSettings = [[FIRRemoteConfigSettings alloc] initWithDeveloperModeEnabled:YES];
    [FIRRemoteConfig remoteConfig].configSettings = remoteConfigSettings;
#endif
```
