Question

我创建了一个junit测试，以检查是否通过单击按钮启动了正确的活动。

@RunWith(RobolectricTestRunner.class)

@Config(constants = BuildConfig.class,    
manifest="src/main/AndroidManifest.xml", sdk = 21)
public class MainActivityTest {

MainActivity activity;
@Before
public void setUp(){
    activity = Robolectric.setupActivity(MainActivity.class);
    activity.findViewById(R.id.login).performClick();
}
@Test
public void clickingLogin_shouldStartLoginActivity() {


    Intent expectedIntent = new Intent(activity, LoginActivity.class);
    assertThat(shadowOf(activity).getNextStartedActivity()).isEqualTo(expectedIntent);

   }
}

基本上，我将当前活动与下一个活动的意图进行比较。但是，我得到了一个非常奇怪的例外。

我的MainActivity代码是

public class MainActivity extends AppCompatActivity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final View button = findViewById(R.id.login);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            startActivity(new Intent(MainActivity.this, LoginActivity.class));
        }
    });
}
}

如何解决此问题？

感谢。

Answer 1

其实我不得不添加这个

@RunWith（RobolectricGradleTestRunner.class）

而不是

@RunWith（RobolectricTestRunner.class）。

使用Roboelectric的RuntimeException
