Let's add Japanese numbers!
Create a folder values-ja
and a strings file under this directory.
Copy the characters from here into your strings.xml folder for keys 0-9: http://en.wikipedia.org/wiki/Japanese_numerals
Robolectric allows you configure the qualifiers for a specific test:
@Test
@Config (qualifiers = "ja")
public void shouldHaveJa0Key()
{
verifyKey( R.id.key0, R.string.key0, "零");
}
I have a helper function to reduce the duplicated code for each key. You could refactor this even further into an array that you loop through to verify each button.
Button key = (Button) buttonFragment.getView()
.findViewById( id );
assertViewIsVisible( key );
String resourceString = getString( stringId );
assertThat( key.getText().toString(),
equalTo( resourceString ) );
assertThat( expectedString,
equalTo( resourceString ) );
Build and change your device's language to Japanese to visually verify the internationalization worked.
