为 Robolectric 的 SharedPreferences 提供测试数据 [英] Providing test data for SharedPreferences for Robolectric
问题描述
刚开始使用 Robolectric，它似乎正是我所需要的.但是，我在使用 SharedPreferences 方面遇到了一些障碍.
Just started to use Robolectric and it seems to be pretty much what I need. However, I've hit a bit of a roadblock with regards to the use of SharedPreferences.
我有两个测试用例
Activity 需要一个新的/空的 sharedPreferences
Activity expects a new/empty sharedPreferences
Activity 需要已经包含一些数据的 sharedPreferences
Activity expects sharedPreferences with some data in it already
对于测试用例 1，测试按预期通过，所以一切都很好:)
For Test Case 1, the tests are passing as expected, so all good :)
然而，对于测试用例 2，我似乎无法找到一种向 Robolectric 提供一些虚假数据的好方法，因此 Activity 能够访问这些虚假数据.
However, for Test Case 2 I can't seem to figure out a nice way to provide Robolectric with some fake data, so the Activity is able to access this fake data.
感觉这是一个很常见的用例，但我似乎不知道该怎么做！
It feels like a very common use case, but I can't seem to figure out how to do it!
推荐答案
找出方法 - 现在看起来很明显！
Found out how - seems so obvious now!
对于那些感兴趣的人，您只需获取 sharedPreferences，并用所需的数据填充它.
For those who are interested, you just get the sharedPreferences, and populate it with the required data.
SharedPreferences sharedPreferences = ShadowPreferenceManager.getDefaultSharedPreferences(Robolectric.application.getApplicationContext());
sharedPreferences.edit().putString("testId", "12345").commit();
如果你有一个自定义的 SharedPreferences，你应该能够做到这一点(还没有真正正确测试，但也应该可以工作)
If you have a custom SharedPreferences, you should be able to do this (haven't really tested properly, but should also work)
SharedPreferences sharedPreferences = Robolectric.application.getSharedPreferences("you_custom_pref_name", Context.MODE_PRIVATE);
sharedPreferences.edit().putString("testId", "12345").commit();
希望这对某人有所帮助:)
Hope this has helped someone :)
