[Robolectric] Robolectric을 이용한 Parameterized testing

@RunWith(ParameterizedRobolectricTestRunner.class)
public class ContactServiceTest {

    @ParameterizedRobolectricTestRunner.Parameters(name = "ErrorCode = {0}")
    public static Collection data() {
        return Arrays.asList(new Object[][]{
                {105, 105_ERROR_MSG},
                {113, 113_ERROR_MSG},
                {114, 114_ERROR_MSG},
                {134, 134_ERROR_MSG},
                {137, 137_ERROR_MSG},
                {999, DEFAULT_ERROR_MSG} // Bogus error code
        });
    }

    private int errorCode;
    private String expectedErrorMsg;

    public ContactServiceTest(int errorCode, String errorMsg) {
        this.errorCode = errorCode;
        this.expectedErrorMsg = errorMsg;
    }

    @Test
    public void when_known_error_code_is_received_from_service_correct_error_msg_is_displayed_to_user() {
        // HTTP response from service contains defined error code
        Robolectric.addPendingHttpResponse(HttpStatus.SC_OK, buildFakeServiceResponse(errorCode)); 
        // Contact the service
        mService.contactService();
        // Use awaitility to wait until error message is displayed to user
        // then assert that the error message is correct
        await().until(getDisplayedErrorMsg(), is(expectedErrorMsg));
    }
