我有两个 fragment 附加到一个 Activity 。
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LoginFragment loginFragment = new LoginFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction =
fragmentManager.beginTransaction();
fragmentTransaction.add(android.R.id.content,loginFragment);
fragmentTransaction.commit();
}
public void userReg(View view){
RegisterFragment regFragment = new RegisterFragment();
FragmentManager fragmentManager1 = getSupportFragmentManager();
FragmentTransaction fragmentTransaction1 =
fragmentManager1.beginTransaction();
fragmentTransaction1.addToBackStack("added");
fragmentTransaction1.replace(android.R.id.content,regFragment);
fragmentTransaction1.commit();
}
}
通过按钮附加的注册 fragment 。现在我想在 robolectric 3.0 中测试它们。
@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class,sdk = 21)
public class MainActivityTest {
MainActivity activity;
@Before
public void setUp(){
activity= Robolectric.setupActivity(MainActivity.class);
}
@Test
public void shouldNotBeNull(){
assertNotNull(activity);
LoginFragment loginFragment = new LoginFragment();
startFragment(loginFragment);
assertNotNull(loginFragment);
}
@Test
public void loginFragmentShouldNotBeNull(){
RegisterFragment registerFragment = new RegisterFragment();
startFragment(registerFragment);
assertNotNull(registerFragment);
}
@Test
public void registerFragmentShouldNotBeNull(){
RegisterFragment registerFragment = new RegisterFragment();
startFragment(registerFragment);
assertNotNull(registerFragment);
}
}
这些线路提示
startFragment(loginFragment);
startFragment(registerFragment);
说startFragment(android.app.Fragment)不能分别应用于LoginFragment和Register fragment。
对于我导入的两个 fragment
import android.support.v4.app.Fragment;
所以这是导致问题的原因。我本可以通过使用固定 fragment 来解决这个问题，但是使用动态 fragment 怎么样？
有什么想法吗？
谢谢。

上述错误已修复。我刚刚添加了
import static org.robolectric.shadows.support.v4.SupportFragmentTestUtil.startFragment;
但是，当我运行测试时，出现了另一个异常。

最佳答案
您的 fragment 继承自“支持 fragment ”(来自 android 支持库的 fragment )，但您的 startFragment() 函数需要常规 fragment 。您可以使用 SupportFragmentTestUtil.startFragment(fragment, activityClass)
支持库允许在尚不支持 fragment 的 API 级别上使用 fragment 。如果您的应用程序需要在 API 11 及更高版本 (Android 3) 上运行 - 您可以直接从 android.app.Fragment 派生您的 fragment
关于android - 使用 Robolectric 3.0 测试 fragment ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38219861/
