Cannot instantiate SecurePrefs in testing

[IgorGanapolsky]

Hi
I am trying to write unit tests, one of which requires an instance of SecurePreferences. So I am passing a context like this:
mContext = Mockito.mock(Context.class);
securePreferences = new SecurePreferences(mContext);

However, the context isn't mocked, and as a result I cannot use SecurePrefs in testing. Do you have any ideas about this?

I've not used Mockito, can you test the standard Shared Preferences ok? if so could you paste a code sample or link to example. thx

The error actually happens because I am running my unit tests on the JVM, and hence don't access to a Context (which SecurePreferences requires).

Ok, understood. But my question still stands if you can show me a test with config working using the standard Shared Preferences then I can see about getting securePreferences working. However if you cannot test standard Shared Preferences then this is not something this library is going to be able to solve.

@IgorGanapolsky How did you solved this situation ?

I am facing the same problem.
Its really weird!

val sp = SecurePreferences(context, context.packageName, PREFS)

I can test SharedPreferences normally but, when I try to get an instance of SecurePreferences with a mocked context throws an NullPointerException in line 85 because its a mocked context and the getDeviceSerialNumber cannot get an instance of ContextResolver in this method:

private static String getDeviceSerialNumber(Context context) {
        try {
            String deviceSerial = (String)Build.class.getField("SERIAL").get((Object)null);
            return TextUtils.isEmpty(deviceSerial) ? Secure.getString(context.getContentResolver(), "android_id") : deviceSerial;
        } catch (Exception var2) {
            return Secure.getString(context.getContentResolver(), "android_id");
        }
    }

I don't know if I am doing something wrong, but, my tests are not passing because of this problem and I am close to delete this library of my project because of that.
