Unit testing?

Is Robolectric a requirement for loading a ZoneInfoProvider? Could there be a mechanism for loading such that doesn’t depend on Android APIs?

I’ve done this by using the standard JVM backport package for unit testing. testCompile 'org.threeten:threetenbp:1.3.1'

Still experimenting, but haven’t run into any issues so far.

To resume for people passing around.

app/build.graddle

dependencies {
    [...]
    compile 'com.jakewharton.threetenabp:threetenabp:1.0.4'
    testCompile ('org.threeten:threetenbp:1.3.2'){
        exclude group:'com.jakewharton.threetenabp', module:'threetenabp'
    }
    testCompile('org.robolectric:robolectric:3.1.2') {
        exclude group: 'commons-logging', module: 'commons-logging'
        exclude group: 'org.apache.httpcomponents', module: 'httpclient'
    }
    [...]
}

Test class

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class, sdk = 21, application = TestApp.class)
public class MessagingTimeFormatterTest {
    [...]
}

TestApp without AndroidThreeTen.init(this)

public class TestApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
    }
}

-> clean & build
