android - "java.lang.SecurityException:Injecting to another application requires INJECT_EVENTS permission"多个 Activity 工作流测试 android 时出错

Question

在我的代码中有 HomeActivity.java。在此 Activity 中，我有 3 个图像按钮，当我单击任何按钮时，它会打开一个带有 intent.putExtra 的新 Activity (ItemListActivity)。

例如:

Intent intent = new Intent(HomeActivity.this, ItemListActivity.class);
                intent.putExtra("for", "files");
                finish();
                startActivity(intent);)**

完整代码如下:

public class HomeActivityTest extends ActivityInstrumentationTestCase2<HomeActivity> {

    private HomeActivity homeActivity;
    ImageView ivFiles;
    ImageView ivForms;
    ImageView ivModels;
    private static final int TIMEOUT_IN_MS = 5000;
    private Intent mLaunchIntent;

    public HomeActivityTest() {
        super(HomeActivity.class);
    }

    @Override
    protected void setUp() throws Exception {
        super.setUp();

        try {
            /**
             * Using ActivityInstrumentationTestCase2
             */

            setActivityInitialTouchMode(true);
            CommonUtilities.createSharedPreferenceEditor(getInstrumentation().getContext());
            homeActivity = getActivity();
            ivFiles = (ImageView) homeActivity.findViewById(R.id.ivFilesBtn);
            ivForms = (ImageView) homeActivity.findViewById(R.id.ivFormsBtn);
            ivModels = (ImageView) homeActivity.findViewById(R.id.ivModelBtn);

            assertNotNull("HomeActivity is null", homeActivity);
            assertNotNull("File Image is null",ivFiles);
            assertNotNull("File Image is null",ivForms);
            assertNotNull("File Image is null",ivModels);
        } catch (Exception e){
            e.printStackTrace();
        }
    }

    @MediumTest
    public void testOpenItemListActivity(){

        Instrumentation.ActivityMonitor receiverActivityMonitor1 = getInstrumentation()
                .addMonitor(ItemListActivity.class.getName(), null, false);

        /*
            When I click on this ivFiles in HomeActivity, it Opens new ItemListActivity.

                Intent intent = new Intent(HomeActivity.this, ItemListActivity.class);
                intent.putExtra("for", "files");
                finish();
                startActivity(intent);
         */
        TouchUtils.clickView(this, ivFiles);

        ItemListActivity itemListActivity1 = (ItemListActivity) receiverActivityMonitor1
                .waitForActivityWithTimeout(TIMEOUT_IN_MS);

        assertNotNull("ItemListActivity is null", itemListActivity1);
        assertEquals("Monitor for ReceiverActivity has not been called", 1,
                receiverActivityMonitor1.getHits());
        assertEquals("Activity is of wrong type", ItemListActivity.class,
                itemListActivity1.getClass());

        assertEquals("Wrong data pass on ivFiles Click", itemListActivity1.dataToOpen, "files");

        getInstrumentation().removeMonitor(receiverActivityMonitor1);

        receiverActivityMonitor1 = getInstrumentation()
                .addMonitor(ItemListActivity.class.getName(), null, false);
        /*
            When I click on this ivFiles in HomeActivity, it Opens new ItemListActivity.

                Intent intent = new Intent(HomeActivity.this, ItemListActivity.class);
                intent.putExtra("for", "files");
                finish();
                startActivity(intent);
         */

        TouchUtils.clickView(this, ivModels);

        ItemListActivity itemListActivity2 = (ItemListActivity) receiverActivityMonitor1
                .waitForActivityWithTimeout(TIMEOUT_IN_MS);

        assertNotNull("ItemListActivity is null", itemListActivity2);
        assertEquals("Monitor for ReceiverActivity has not been called", 1,
                receiverActivityMonitor1.getHits());
        assertEquals("Activity is of wrong type", ItemListActivity.class,
                itemListActivity1.getClass());

        assertEquals("Wrong data pass on ivModels Click", itemListActivity2.dataToOpen, "models");

        getInstrumentation().removeMonitor(receiverActivityMonitor1);

    }
    }

我已经为这个 HomeActivity 写了一个测试用例，它是 HomeActivityTest.java。但是我收到了这个错误:

java.lang.SecurityException: Injecting to another application requires INJECT_EVENTS permission

那么我应该如何测试这种场景呢？
