ES preSSO startActivity取决于意图 [英] Espresso startActivity that depends on Intent

问题描述

我有以下的情况。

我的活动都有所依赖的序列化对象的片段。这是我的onCreate：

My activity has a fragment that depends of a Serializable Object. Here is my onCreate:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    MyObject myObj = (MyObj) getIntent().getSerializableExtra("myobj");

    if(myObj != null) {
        FragmentManager manager = getSupportFragmentManager();
        FragmentTransaction transaction = manager.beginTransaction();
        transaction.add(R.id.container, MyFragment.newInstance(myObj));
        transaction.commit();
    }
}

但在我的长者preSSO测试，我根本无法意图的创建之前将它传递给活动。我setActivityIntent试过多种方法，但无法弄清楚如何使它发挥作用。

But in my Espresso test I simply can't pass the intent to the activity before it's created. I tried with setActivityIntent in several ways but cant figure out how to make it work.

这是我最后一次尝试：

import android.content.Intent;
import android.support.test.InstrumentationRegistry;
import android.support.test.espresso.Espresso;
import android.test.ActivityInstrumentationTestCase2;
import org.junit.Before;

import static android.support.test.espresso.assertion.ViewAssertions.matches;
import static android.support.test.espresso.matcher.ViewMatchers.withId;
import static android.support.test.espresso.matcher.ViewMatchers.withText;

public class MyActivityTest extends

     ActivityInstrumentationTestCase2<MyActivity> {

        private MyActivity activity;
        private MyObject myObj;

        public MyActivityTest() {
            super(MyActivity.class);
        }

        @Before
        protected void setUp() throws Exception {
            super.setUp();
            injectInstrumentation(InstrumentationRegistry.getInstrumentation());
            myObj = MyObject.mockObject();
            Intent i = new Intent();
            i.putExtra("myobj", myObj);
            setActivityIntent(i);

        }

        public void testName(){
            Espresso.onView(withId(R.id.name)).check(matches(withText(myObj.getObjName())));
        }

    }

我已经搜查了很多，但没有任何工程。 为MyObject 总是在测试空。我想这应该很简单。我是什么我失踪？

I've searched a lot but nothing works. MyObject is always null in the test. I think this should be simple. What am I'm missing?

推荐答案

您可以定义意图以这种方式使用

You can define the Intent to be used in this way

@RunWith(AndroidJUnit4.class)
public class MyActivityTestTest {

    private MyObject myObj;

    @Rule
    // third parameter is set to false which means the activity is not started automatically
    public ActivityTestRule<MyActivity> mActivityRule =
        new ActivityTestRule<>(MyActivity.class, false, false);


    @Test
    public void testName() {

          myObj = MyObject.mockObject();
          Intent i = new Intent();
          i.putExtra("myobj", myObj);
          mActivityRule.launchActivity(intent);

         //...
    }

}
