MainActivityTest - configuring MockWebServer

MainActivityTest.java

@RunWith(AndroidJUnit4.class)
public class MainActivityTest {

  private MockWebServer server;
  
  @Rule
  public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule<>(MainActivity.class, false, false);
  
  @Before
  public void setUp() throws Exception {
      server = new MockWebServer();
      server.start();
  }
  
  @After
  public void tearDown() throws IOException {
      server.shutdown();
  }
}

its pretty cool
