如何将UnitTest和EspressoTest与翻新配合使用？

Question

在我的应用程序中，我使用 Retrofit 从服务器获取数据，并使用 Room 将其保存到数据库中。
我想在RecyclerView adapter上单击按钮时，将此项目保存到数据库中。

我可以，当单击按钮时，我可以将其保存到 Room 数据库中。

但是我要为此编写测试，但是我不知道从服务器加载数据后如何运行测试！

我编写了将静态数据保存到数据库的测试：

@LargeTest
@RunWith(AndroidJUnit4.class)
public class AddPersonTest {

    @Rule
    public ActivityTestRule<ListActivity> mActivityTestRule = new ActivityTestRule<>(ListActivity.class);

    @Test
    public void addPersonTest() {
        ViewInteraction floatingActionButton = onView(allOf(withId(R.id.fab), isDisplayed()));
        floatingActionButton.perform(click());

        ViewInteraction appCompatEditText = onView(
                withId(R.id.nameEditText));
        appCompatEditText.perform(scrollTo(), replaceText("Daniel Alvarez"), closeSoftKeyboard());

        ViewInteraction appCompatEditText2 = onView(
                withId(R.id.addressEditText));
        appCompatEditText2.perform(scrollTo(), replaceText("La Paz, Bolivia"), closeSoftKeyboard());

        ViewInteraction appCompatEditText3 = onView(
                withId(R.id.phoneEditText));
        appCompatEditText3.perform(scrollTo(), replaceText("591 77242424"), closeSoftKeyboard());

        ViewInteraction appCompatEditText4 = onView(
                withId(R.id.emailEditText));
        appCompatEditText4.perform(scrollTo(), replaceText("daniel@alvarez.tech"), closeSoftKeyboard());

        ViewInteraction appCompatEditText5 = onView(
                withId(R.id.birthdayEditText));
        appCompatEditText5.perform(scrollTo(), click());

        ViewInteraction appCompatImageButton = onView(
                allOf(withClassName(is("android.support.v7.widget.AppCompatImageButton")), withContentDescription("Previous month"),
                        withParent(allOf(withClassName(is("android.widget.DayPickerView")),
                                withParent(withClassName(is("com.android.internal.widget.DialogViewAnimator"))))),
                        isDisplayed()));
        appCompatImageButton.perform(click());

        ViewInteraction appCompatImageButton2 = onView(
                allOf(withClassName(is("android.support.v7.widget.AppCompatImageButton")), withContentDescription("Previous month"),
                        withParent(allOf(withClassName(is("android.widget.DayPickerView")),
                                withParent(withClassName(is("com.android.internal.widget.DialogViewAnimator"))))),
                        isDisplayed()));
        appCompatImageButton2.perform(click());

        ViewInteraction appCompatImageButton3 = onView(
                allOf(withClassName(is("android.support.v7.widget.AppCompatImageButton")), withContentDescription("Previous month"),
                        withParent(allOf(withClassName(is("android.widget.DayPickerView")),
                                withParent(withClassName(is("com.android.internal.widget.DialogViewAnimator"))))),
                        isDisplayed()));
        appCompatImageButton3.perform(click());

        ViewInteraction appCompatImageButton4 = onView(
                allOf(withClassName(is("android.support.v7.widget.AppCompatImageButton")), withContentDescription("Previous month"),
                        withParent(allOf(withClassName(is("android.widget.DayPickerView")),
                                withParent(withClassName(is("com.android.internal.widget.DialogViewAnimator"))))),
                        isDisplayed()));
        appCompatImageButton4.perform(click());

        ViewInteraction appCompatButton = onView(
                allOf(withId(android.R.id.button1), withText("OK")));
        appCompatButton.perform(scrollTo(), click());

        ViewInteraction floatingActionButton2 = onView(allOf(withId(R.id.fab), isDisplayed()));
        floatingActionButton2.perform(click());

        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        onView(withId(R.id.list)).perform(RecyclerViewActions.actionOnItemAtPosition(0, click()));

        onView(withId(R.id.nameEditText)).check(matches(withText("Daniel Alvarez")));
        onView(withId(R.id.addressEditText)).check(matches(withText("La Paz, Bolivia")));
        onView(withId(R.id.phoneEditText)).check(matches(withText("591 77242424")));
        onView(withId(R.id.emailEditText)).check(matches(withText("daniel@alvarez.tech")));
    }

    private static Matcher<View> childAtPosition(
            final Matcher<View> parentMatcher, final int position) {

        return new TypeSafeMatcher<View>() {
            @Override
            public void describeTo(Description description) {
                description.appendText("Child at position " + position + " in parent ");
                parentMatcher.describeTo(description);
            }

            @Override
            public boolean matchesSafely(View view) {
                ViewParent parent = view.getParent();
                return parent instanceof ViewGroup && parentMatcher.matches(parent)
                        && view.equals(((ViewGroup) parent).getChildAt(position));
            }
        };
    }
}

运行此测试时，将数据添加到数据库中，但是我想从服务器加载数据后，单击适配器的按钮，并在保存到数据库时从适配器的模型中获取数据！

如何编写此测试？
